Part II-E — Terrier breeds (38)

Airedale Terrier

Origin and purpose

Terrier (AKC). Origin: England (Aire valley).

The largest of the terrier breeds.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Confident, courageous, alert; the 'king of terriers'.

Reward-based training from the day the puppy arrives, with the socialisation window (roughly three to sixteen weeks) treated as the priority it is — what happens in those weeks shapes the adult dog more than anything you do later. Short, frequent, positive sessions. See Parts IV and IX.

Health — what this breed is predisposed to

Drawn from this breed's documented health issues and cross-referenced to Part III. A predisposition is not a prophecy — most dogs of any breed never develop these — but it is what you and your vet should be watching for.

• Gastric dilatation and volvulus (GDV, 'bloat') (EMERGENCY) — stomach twists on itself.
• Atopic dermatitis (canine atopy) (Routine) — allergic skin disease.
• Hip dysplasia (Routine) — abnormal hip joint development.
• Hypothyroidism (Routine) — underactive thyroid.

Health screening — what to test, and when

Derived from the predispositions above. Take this list to your vet; it is a starting point for a conversation, not a prescription, and your vet may reasonably add to it or leave items out for your dog.

Every dog, every breed: an annual health examination (twice yearly from seven years), body-condition scoring at each visit, dental assessment, year-round parasite control, and the core vaccinations.

Vaccination is NOT breed-specific, and any source that claims a breed-specific vaccination schedule should be treated with suspicion. The core schedule — the puppy series and its boosters, and rabies above all — is the same for this dog as for every other, and is set out in Parts VI and IX. What IS specific to the dog is its exposure: a dog that swims, roams, or lives where monsoon flooding occurs has a different leptospirosis risk from an apartment dog, and a dog that boards or meets many other dogs has a different kennel-cough risk. Discuss the dog's actual life with your vet, not its breed.

For breeders — test before you mate

The heritable subset of the screening above. These are the tests a responsible breeder of this breed completes BEFORE a mating, and the results a buyer is entitled to ask to see. A breeder who cannot produce them is telling you something. See Part XII.

• Atopic dermatitis (canine atopy) — No screening test; allergy testing once disease is established
• Gastric dilatation and volvulus (GDV, 'bloat') — No screening test. Discuss preventive gastropexy with your vet in deep-chested breeds
• Hip dysplasia — Radiographic hip evaluation (hip scoring)
• Hypothyroidism — Thyroid blood panel

Feeding

Growth is the thing that matters. Large-breed puppies must be fed a diet formulated for large-breed growth and must NOT be overfed or supplemented with calcium — growing too fast is a direct route to the joint disease this size of dog is already prone to. A lean puppy is a healthy puppy. As an adult, two measured meals a day, and keep the dog lean for life: excess weight is the single biggest accelerator of hip and elbow disease and arthritis.

This breed is deep-chested and at risk of gastric dilatation and volvulus (bloat), which kills quickly. Feed two or more smaller meals rather than one large one, avoid vigorous exercise for an hour either side of eating, and slow down a gulping eater. Learn the signs — a restless dog with a swelling belly, retching without bringing anything up — and treat them as an immediate emergency. Ask your vet whether a preventive gastropexy is appropriate at neutering.

Exercise and enrichment

Stated requirement: High.

A high-energy dog needing substantial, committed daily exercise plus mental work. Do not take this breed on unless the daily commitment is realistic on your worst week, not your best one.

Coat and grooming

Harsh, wiry coat. Brush weekly; hand-strip or clip every 8–12 weeks.

Climate and living conditions

Stated suitability: Moderate heat tolerance; grooming (hand-stripping) is intensive..

Ageing and senior care

Life expectancy: 11–14 years. This dog is a senior from around 7 years, at which point wellness examinations should move to twice a year and senior blood and urine screening begins. Large dogs age faster than small ones. Arthritis and cancer are the dominant concerns; do not dismiss a limp in an older large dog as 'just age' — bone cancer presents exactly that way. See Part X.

Before you take one home

• Ask the breeder for the health-test results listed above — for BOTH parents, on paper, before you pay a deposit. A breeder who has done the tests will be proud to show you; one who deflects, or who tells you the tests are unnecessary in this line, is telling you what you need to know.
• Consider adoption. Shelters and rescues have dogs of every kind, including purebreds, and the local native or landrace dog is often healthier, better adapted to its climate, and more in need of a home than almost anything you can buy. See Part XII.

DRAFT — VET REVIEW PENDING. The predispositions, screening schedule, and breeder tests above are derived from this breed's recorded health issues; the feeding, exercise, climate, training, and ageing guidance is derived from its size, skull shape, coat, and temperament. Both are drafts until a veterinarian signs them off (Appendix A.3).

American Hairless Terrier

Origin and purpose

Terrier (AKC); not FCI-recognised. Origin: United States (Louisiana); companion terrier bred from Rat Terrier.

The only hairless breed developed in the USA; both hairless and coated varieties exist.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Lively, inquisitive and affectionate; an energetic, people-oriented terrier.

Reward-based training from the day the puppy arrives, with the socialisation window (roughly three to sixteen weeks) treated as the priority it is — what happens in those weeks shapes the adult dog more than anything you do later. Short, frequent, positive sessions. See Parts IV and IX.

Health — what this breed is predisposed to

Drawn from this breed's documented health issues and cross-referenced to Part III. A predisposition is not a prophecy — most dogs of any breed never develop these — but it is what you and your vet should be watching for.

• Atopic dermatitis (canine atopy) (Routine) — allergic skin disease.
• Legg-Calvé-Perthes disease (Routine) — femoral head necrosis in small breeds (Toy, terriers).
• Patellar luxation (Routine) — kneecap slips out of groove.

Health screening — what to test, and when

Derived from the predispositions above. Take this list to your vet; it is a starting point for a conversation, not a prescription, and your vet may reasonably add to it or leave items out for your dog.

The heritable subset of the screening above. These are the tests a responsible breeder of this breed completes BEFORE a mating, and the results a buyer is entitled to ask to see. A breeder who cannot produce them is telling you something. See Part XII.

• Atopic dermatitis (canine atopy) — No screening test; allergy testing once disease is established
• Legg-Calvé-Perthes disease — Hip radiographs
• Patellar luxation — Patellar palpation by a vet

Feeding

Small stomachs, fast metabolisms. Feed a diet formulated for small breeds, split across three or four meals a day as a puppy and two as an adult; toy puppies can become dangerously hypoglycaemic if a meal is missed. Portions are tiny, which means treats and table scraps overwhelm the daily allowance startlingly fast — a single biscuit can be a meaningful share of a 4 kg dog's intake. Dental disease is near-universal in small breeds, so ask your vet about diet texture and dental care from the start.

Exercise and enrichment

Stated requirement: Moderate - 30-45 min/day.

Moderate daily exercise plus mental stimulation. Adaptable to apartment life provided the daily walk actually happens every day.

Climate and living conditions

Stated suitability: Moderate - the hairless skin burns easily and needs sun protection in strong sun; it is low-dander for allergy sufferers..

Ageing and senior care

Life expectancy: 14-16 years. This dog is a senior from around 9–10 years, at which point wellness examinations should move to twice a year and senior blood and urine screening begins. Small dogs age slowly and often live into their mid-teens. Dental disease and heart-valve disease are the two things that most often shorten a small dog's life, and both are catchable early. See Part X.

American Pit Bull Terrier / American Bully

Origin and purpose

Terrier (not AKC-recognised as Pit Bull; American Bully recognised by UKC). Origin: United States.

Not recommended for a first-time owner. Legality varies by jurisdiction.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Confident, strong-willed, loyal; historically strong bite pressure; requires expert handling.

Reward-based training from the day the puppy arrives, with the socialisation window (roughly three to sixteen weeks) treated as the priority it is — what happens in those weeks shapes the adult dog more than anything you do later. Short, frequent, positive sessions. See Parts IV and IX.

A high-energy dog needing substantial, committed daily exercise plus mental work. Do not take this breed on unless the daily commitment is realistic on your worst week, not your best one.

Climate and living conditions

Stated suitability: Adaptable but controversial; subject to breed-specific restrictions in several jurisdictions..

Ageing and senior care

Life expectancy: 10–14 years. This dog is a senior from around 7 years, at which point wellness examinations should move to twice a year and senior blood and urine screening begins.

American Staffordshire Terrier

Origin and purpose

Terrier (AKC). Origin: United States.

A strong, muscular terrier; breed-specific legislation restricts ownership in some jurisdictions, so check local regulations.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Loyal, confident, playful; requires firm handling.

Reward-based training from the day the puppy arrives, with the socialisation window (roughly three to sixteen weeks) treated as the priority it is — what happens in those weeks shapes the adult dog more than anything you do later. Short, frequent, positive sessions. See Parts IV and IX.

Australian Terrier

Origin and purpose

Terrier (AKC); FCI Group 3. Origin: Australia; vermin, snake-killing and watchdog terrier.

One of the first native breeds developed and shown in Australia.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Spirited, confident and affectionate; a small, hardy and adaptable companion.

Reward-based training from the day the puppy arrives, with the socialisation window (roughly three to sixteen weeks) treated as the priority it is — what happens in those weeks shapes the adult dog more than anything you do later. Short, frequent, positive sessions. See Parts IV and IX.

Health — what this breed is predisposed to

Drawn from this breed's documented health issues and cross-referenced to Part III. A predisposition is not a prophecy — most dogs of any breed never develop these — but it is what you and your vet should be watching for.

• Diabetes mellitus (URGENT) — insulin-dependent.
• Legg-Calvé-Perthes disease (Routine) — femoral head necrosis in small breeds (Toy, terriers).
• Patellar luxation (Routine) — kneecap slips out of groove.

Health screening — what to test, and when

Derived from the predispositions above. Take this list to your vet; it is a starting point for a conversation, not a prescription, and your vet may reasonably add to it or leave items out for your dog.

Every dog, every breed: an annual health examination (twice yearly from seven years), body-condition scoring at each visit, dental assessment, year-round parasite control, and the core vaccinations.

Vaccination is NOT breed-specific, and any source that claims a breed-specific vaccination schedule should be treated with suspicion.

For breeders — test before you mate

The heritable subset of the screening above. These are the tests a responsible breeder of this breed completes BEFORE a mating, and the results a buyer is entitled to ask to see. A breeder who cannot produce them is telling you something. See Part XII.

• Diabetes mellitus — Blood and urine glucose
• Legg-Calvé-Perthes disease — Hip radiographs
• Patellar luxation — Patellar palpation by a vet

Feeding

Small stomachs, fast metabolisms. Feed a diet formulated for small breeds, split across three or four meals a day as a puppy and two as an adult; toy puppies can become dangerously hypoglycaemic if a meal is missed. Portions are tiny, which means treats and table scraps overwhelm the daily allowance startlingly fast — a single biscuit can be a meaningful share of a 4 kg dog's intake. Dental disease is near-universal in small breeds, so ask your vet about diet texture and dental care from the start.

Exercise and enrichment

Stated requirement: Moderate - 30-45 min/day.

Moderate daily exercise plus mental stimulation. Adaptable to apartment life provided the daily walk actually happens every day.

Climate and living conditions

Stated suitability: Good for warm climates - the harsh weather-resistant coat needs little clipping and tolerates heat with shade..

Ageing and senior care

Life expectancy: 12-15 years. This dog is a senior from around 9–10 years, at which point wellness examinations should move to twice a year and senior blood and urine screening begins. Small dogs age slowly and often live into their mid-teens. Dental disease and heart-valve disease are the two things that most often shorten a small dog's life, and both are catchable early. See Part X.

Bedlington Terrier

Origin and purpose

Terrier (AKC); FCI Group 3. Origin: England (Northumberland); vermin killer and pit racing terrier.

Hereditary copper-storage disease makes pre-breeding DNA testing important.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Mild and affectionate indoors, tenacious when roused; lamb-like look, genuine terrier grit.

Reward-based training from the day the puppy arrives, with the socialisation window (roughly three to sixteen weeks) treated as the priority it is — what happens in those weeks shapes the adult dog more than anything you do later. Short, frequent, positive sessions. See Parts IV and IX.

Exercise and enrichment

Stated requirement: Moderate - 45-60 min/day.

Moderate daily exercise plus mental stimulation. Adaptable to apartment life provided the daily walk actually happens every day.

Climate and living conditions

Stated suitability: Adaptable across climates - the curly, low-shedding coat produces little dander but needs regular clipping and grooming; provide shade in heat..

Ageing and senior care

Life expectancy: 12-14 years. This dog is a senior from around 9–10 years, at which point wellness examinations should move to twice a year and senior blood and urine screening begins.

Border Terrier

Origin and purpose

Terrier (AKC). Origin: England/Scotland border.

One of the most family-friendly terriers.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Alert, plucky, biddable — one of the more trainable terriers.

This is a biddable breed that wants to work with you, which makes it forgiving of a novice's mistakes — but biddability is not the same as needing no training. Reward-based training, started early and kept short and frequent, is what these dogs thrive on. Punishment-based methods damage exactly the willingness that makes the breed easy.

Health — what this breed is predisposed to

Drawn from this breed's documented health issues and cross-referenced to Part III. A predisposition is not a prophecy — most dogs of any breed never develop these — but it is what you and your vet should be watching for.

• Hip dysplasia (Routine) — abnormal hip joint development.
• Progressive retinal atrophy (Routine) — genetic retinal degeneration.

Health screening — what to test, and when

Derived from the predispositions above. Take this list to your vet; it is a starting point for a conversation, not a prescription, and your vet may reasonably add to it or leave items out for your dog.

Every dog, every breed: an annual health examination (twice yearly from seven years), body-condition scoring at each visit, dental assessment, year-round parasite control, and the core vaccinations.

Vaccination is NOT breed-specific, and any source that claims a breed-specific vaccination schedule should be treated with suspicion. The core schedule — the puppy series and its boosters, and rabies above all — is the same for this dog as for every other, and is set out in Parts VI and IX. What IS specific to the dog is its exposure: a dog that swims, roams, or lives where monsoon flooding occurs has a different leptospirosis risk from an apartment dog, and a dog that boards or meets many other dogs has a different kennel-cough risk. Discuss the dog's actual life with your vet, not its breed.

For breeders — test before you mate

The heritable subset of the screening above. These are the tests a responsible breeder of this breed completes BEFORE a mating, and the results a buyer is entitled to ask to see. A breeder who cannot produce them is telling you something. See Part XII.

• Hip dysplasia — Radiographic hip evaluation (hip scoring)
• Progressive retinal atrophy — Ophthalmologist eye examination, plus DNA test where one exists for the breed

Feeding

Small stomachs, fast metabolisms. Feed a diet formulated for small breeds, split across three or four meals a day as a puppy and two as an adult; toy puppies can become dangerously hypoglycaemic if a meal is missed. Portions are tiny, which means treats and table scraps overwhelm the daily allowance startlingly fast — a single biscuit can be a meaningful share of a 4 kg dog's intake. Dental disease is near-universal in small breeds, so ask your vet about diet texture and dental care from the start.

Exercise and enrichment

Stated requirement: Moderate to high.

A high-energy dog needing substantial, committed daily exercise plus mental work. Do not take this breed on unless the daily commitment is realistic on your worst week, not your best one.

Coat and grooming

Harsh, wiry double coat. Brush weekly; hand-strip twice a year.

Climate and living conditions

Stated suitability: Good heat tolerance; well suited to apartment living..

This breed carries a heavy double coat evolved for cold. It can be kept in a hot climate, but only with genuine commitment: shade and water at all times, exercise confined to the cool hours, and often air-conditioning through summer. Do NOT shave the double coat — counter-intuitively it insulates against heat as well as cold, and shaving it can ruin the coat and expose the skin to sunburn. Watch closely for heat stress, and think hard about whether the climate you live in is fair to this dog before acquiring one.

Ageing and senior care

Life expectancy: 12–15 years. This dog is a senior from around 9–10 years, at which point wellness examinations should move to twice a year and senior blood and urine screening begins. Small dogs age slowly and often live into their mid-teens. Dental disease and heart-valve disease are the two things that most often shorten a small dog's life, and both are catchable early.

Before you take one home

• Ask the breeder for the health-test results listed above — for BOTH parents, on paper, before you pay a deposit. A breeder who has done the tests will be proud to show you; one who deflects, or who tells you the tests are unnecessary in this line, is telling you what you need to know.
• Consider adoption. Shelters and rescues have dogs of every kind, including purebreds, and the local native or landrace dog is often healthier, better adapted to its climate, and more in need of a home than almost anything you can buy. See Part XII.

The predispositions, screening schedule, and breeder tests above are derived from this breed's recorded health issues; the feeding, exercise, climate, training, and ageing guidance is derived from its size, skull shape, coat, and temperament. Both are drafts until a veterinarian signs them off (Appendix A.3).

Bull Terrier

Origin and purpose

Terrier (AKC). Origin: England, 19th century.

Compulsive-behaviour tendencies (tail-chasing) in some lines. BAER hearing test recommended for puppies.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Playful, mischievous, strong-willed; requires firm training.

Reward-based training from the day the puppy arrives, with the socialisation window (roughly three to sixteen weeks) treated as the priority it is — what happens in those weeks shapes the adult dog more than anything you do later. Short, frequent, positive sessions. See Parts IV and IX.

Health — what this breed is predisposed to

Drawn from this breed's documented health issues and cross-referenced to Part III. A predisposition is not a prophecy — most dogs of any breed never develop these — but it is what you and your vet should be watching for.

• Chronic kidney disease (CKD) (URGENT) — the leading senior chronic condition.
• Congenital deafness (Routine) — Present from birth and permanent.
• Mitral valve disease (Routine) — degenerative valve disease; most common in senior small breeds (Cavalier King Charles, Dachshund, Chihuahua).

Health screening — what to test, and when

Derived from the predispositions above. Take this list to your vet; it is a starting point for a conversation, not a prescription, and your vet may reasonably add to it or leave items out for your dog.

Every dog, every breed: an annual health examination (twice yearly from seven years), body-condition scoring at each visit, dental assessment, year-round parasite control, and the core vaccinations.

Vaccination is NOT breed-specific, and any source that claims a breed-specific vaccination schedule should be treated with suspicion. The core schedule — the puppy series and its boosters, and rabies above all — is the same for this dog as for every other, and is set out in Parts VI and IX. What IS specific to the dog is its exposure: a dog that swims, roams, or lives where monsoon flooding occurs has a different leptospirosis risk from an apartment dog, and a dog that boards or meets many other dogs has a different kennel-cough risk. Discuss the dog's actual life with your vet, not its breed.

For breeders — test before you mate

The heritable subset of the screening above. These are the tests a responsible breeder of this breed completes BEFORE a mating, and the results a buyer is entitled to ask to see. A breeder who cannot produce them is telling you something. See Part XII.

• Chronic kidney disease (CKD) — Blood (creatinine, SDMA) with urine concentration
• Congenital deafness — BAER hearing test
• Mitral valve disease — Cardiac auscultation; echocardiography once a murmur is heard

Feeding

Growth is the thing that matters. Large-breed puppies must be fed a diet formulated for large-breed growth and must NOT be overfed or supplemented with calcium — growing too fast is a direct route to the joint disease this size of dog is already prone to. A lean puppy is a healthy puppy. As an adult, two measured meals a day, and keep the dog lean for life: excess weight is the single biggest accelerator of hip and elbow disease and arthritis.

Exercise and enrichment

Stated requirement: High — 60 min/day.

A high-energy dog needing substantial, committed daily exercise plus mental work. Do not take this breed on unless the daily commitment is realistic on your worst week, not your best one.

Coat and grooming

Very short, flat coat. Weekly rub-down. Pink-skinned dogs sunburn.

Climate and living conditions

Stated suitability: Moderate; a committed handler is required..

HEAT IS THE DEFINING WELFARE ISSUE FOR THIS BREED IN ANY HOT CLIMATE. A short skull means a compromised airway, and dogs cool themselves by panting — so this dog cannot cool itself efficiently, and heat and humidity are therefore genuinely dangerous to it rather than merely uncomfortable. Walk only at dawn and dusk, never on hot ground, never in the midday sun, and never leave it in a vehicle even briefly. Keep it lean: excess weight makes the airway worse. Air-conditioning is not a luxury for this breed in a hot climate. Learn the signs of heatstroke (see Part III) and treat any laboured breathing in heat as an emergency. Airlines frequently refuse to carry these breeds, and they are right to.

Ageing and senior care

Life expectancy: 11–14 years. This dog is a senior from around 7 years, at which point wellness examinations should move to twice a year and senior blood and urine screening begins. Large dogs age faster than small ones. Arthritis and cancer are the dominant concerns; do not dismiss a limp in an older large dog as 'just age' — bone cancer presents exactly that way. See Part X.

Before you take one home

• Ask the breeder for the health-test results listed above — for BOTH parents, on paper, before you pay a deposit. A breeder who has done the tests will be proud to show you; one who deflects, or who tells you the tests are unnecessary in this line, is telling you what you need to know.
• This is a short-skulled breed. Choose the puppy with the most open nostrils and the longest muzzle you can find, and reject any that snores, snorts, or struggles for breath at rest — those are not endearing breed traits, they are signs of a dog that cannot breathe properly. Ask whether the parents have been BOAS-graded. In a hot climate this decision has consequences you will live with daily.
• Consider adoption. Shelters and rescues have dogs of every kind, including purebreds, and the local native or landrace dog is often healthier, better adapted to its climate, and more in need of a home than almost anything you can buy. See Part XII.

Cairn Terrier

Origin and purpose

Terrier (AKC). Origin: Scotland.

One of the most robust of the small terriers, originating in the Scottish Highlands.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Cheerful, bold, active; the original 'Toto' from Wizard of Oz.

Reward-based training from the day the puppy arrives, with the socialisation window (roughly three to sixteen weeks) treated as the priority it is — what happens in those weeks shapes the adult dog more than anything you do later. Short, frequent, positive sessions. See Parts IV and IX.

Health — what this breed is predisposed to

Drawn from this breed's documented health issues and cross-referenced to Part III. A predisposition is not a prophecy — most dogs of any breed never develop these — but it is what you and your vet should be watching for.

• Portosystemic shunt (URGENT) — abnormal blood vessel bypassing liver.
• Hip dysplasia (Routine) — abnormal hip joint development.
• Patellar luxation (Routine) — kneecap slips out of groove.

Health screening — what to test, and when

Derived from the predispositions above. Take this list to your vet; it is a starting point for a conversation, not a prescription, and your vet may reasonably add to it or leave items out for your dog.

Every dog, every breed: an annual health examination (twice yearly from seven years), body-condition scoring at each visit, dental assessment, year-round parasite control, and the core vaccinations.

For breeders — test before you mate

The heritable subset of the screening above. These are the tests a responsible breeder of this breed completes BEFORE a mating, and the results a buyer is entitled to ask to see. A breeder who cannot produce them is telling you something. See Part XII.

• Hip dysplasia — Radiographic hip evaluation (hip scoring)
• Patellar luxation — Patellar palpation by a vet
• Portosystemic shunt — Bile-acid blood test; imaging

Feeding

Small stomachs, fast metabolisms. Feed a diet formulated for small breeds, split across three or four meals a day as a puppy and two as an adult; toy puppies can become dangerously hypoglycaemic if a meal is missed. Portions are tiny, which means treats and table scraps overwhelm the daily allowance startlingly fast — a single biscuit can be a meaningful share of a 4 kg dog's intake. Dental disease is near-universal in small breeds, so ask your vet about diet texture and dental care from the start.

Exercise and enrichment

Stated requirement: Moderate to high.

A high-energy dog needing substantial, committed daily exercise plus mental work. Do not take this breed on unless the daily commitment is realistic on your worst week, not your best one.

Coat and grooming

Harsh, weather-resistant coat. Brush weekly; hand-strip twice a year.

Climate and living conditions

Stated suitability: Good heat tolerance; well suited to apartment living..

Ageing and senior care

Life expectancy: 12–15 years. This dog is a senior from around 9–10 years, at which point wellness examinations should move to twice a year and senior blood and urine screening begins. Small dogs age slowly and often live into their mid-teens. Dental disease and heart-valve disease are the two things that most often shorten a small dog's life, and both are catchable early. See Part X.

Cesky Terrier

Origin and purpose

Terrier (AKC); FCI Group 3. Origin: Czech Republic; hunting terrier (Sealyham x Scottish Terrier).

Created in the 1940s by Frantisek Horak; the national terrier of the Czech Republic.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Calmer and more trainable than most terriers; reserved with strangers, devoted at home.

This is a biddable breed that wants to work with you, which makes it forgiving of a novice's mistakes — but biddability is not the same as needing no training. Reward-based training, started early and kept short and frequent, is what these dogs thrive on. Punishment-based methods damage exactly the willingness that makes the breed easy.

Health — what this breed is predisposed to

No breed-linked conditions are recorded for this breed. For landraces and village dogs this is often a genuine finding rather than a gap — a broad genetic base leaves them with markedly fewer inherited disorders than the closed-studbook breeds, and it is one of the strongest arguments for them. The routine risks that apply to every dog — parasites, tick-borne disease, heat — still apply here.

Every dog, every breed: an annual health examination (twice yearly from seven years), body-condition scoring at each visit, dental assessment, year-round parasite control, and the core vaccinations.

Vaccination is NOT breed-specific, and any source that claims a breed-specific vaccination schedule should be treated with suspicion. The core schedule — the puppy series and its boosters, and rabies above all — is the same for this dog as for every other, and is set out in Parts VI and IX.

Dental disease is near-universal in small breeds, so ask your vet about diet texture and dental care from the start.

Exercise and enrichment

Stated requirement: Moderate - 45 min/day.

Moderate daily exercise plus mental stimulation. Adaptable to apartment life provided the daily walk actually happens every day.

Climate and living conditions

Stated suitability: Moderate and adaptable - the silky coat is clipped rather than stripped and needs regular grooming; provide shade in heat..

Ageing and senior care

Life expectancy: 12-15 years. This dog is a senior from around 9–10 years, at which point wellness examinations should move to twice a year and senior blood and urine screening begins.

Dandie Dinmont Terrier

Origin and purpose

Terrier (AKC); FCI Group 3. Origin: Scottish/English Borders; badger and otter terrier.

Named after a character in Sir Walter Scott's novel Guy Mannering; a vulnerable breed.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Dignified, affectionate and independent; the topknot-crowned gentleman of terriers.

This is an independent-minded breed that was developed to make its own decisions, and it will not work for you simply because you asked. That is not stubbornness or stupidity — it is the trait the breed was selected for. Training must be genuinely rewarding to the dog, and expectations of instant, military obedience are misplaced. Recall, in particular, is often unreliable in these breeds; be honest about that before letting one off-lead near traffic.

Health — what this breed is predisposed to

Drawn from this breed's documented health issues and cross-referenced to Part III. A predisposition is not a prophecy — most dogs of any breed never develop these — but it is what you and your vet should be watching for.

• Intervertebral disc disease (IVDD) (EMERGENCY) — disc herniation.
• Glaucoma (URGENT) — elevated intraocular pressure.
• Hypothyroidism (Routine) — underactive thyroid.

Health screening — what to test, and when

Derived from the predispositions above. Take this list to your vet; it is a starting point for a conversation, not a prescription, and your vet may reasonably add to it or leave items out for your dog.

• Glaucoma — Eye-pressure measurement (tonometry); gonioscopy in predisposed breeds
• Hypothyroidism — Thyroid blood panel
• Intervertebral disc disease (IVDD) — DNA test for the chondrodystrophy variant; imaging if signs appear

Feeding

Small stomachs, fast metabolisms. Feed a diet formulated for small breeds, split across three or four meals a day as a puppy and two as an adult; toy puppies can become dangerously hypoglycaemic if a meal is missed.

Stated requirement: Moderate - 30-45 min/day; discourage jumping.

Moderate daily exercise plus mental stimulation. Adaptable to apartment life provided the daily walk actually happens every day.

Climate and living conditions

Stated suitability: Moderate - the pily double coat needs regular grooming; avoid heat stress and provide shade in warm weather..

Fox Terrier (Wire)

Origin and purpose

Terrier (AKC). Origin: England.

The coat requires professional hand-stripping.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Bold, energetic, playful; classic terrier temperament.

Reward-based training from the day the puppy arrives, with the socialisation window (roughly three to sixteen weeks) treated as the priority it is — what happens in those weeks shapes the adult dog more than anything you do later. Short, frequent, positive sessions. See Parts IV and IX.

Glen of Imaal Terrier

Origin and purpose

Terrier (AKC); FCI Group 3. Origin: Ireland (County Wicklow); badger, fox and vermin terrier.

Bow-fronted, low-slung Irish terrier; historically a 'turnspit' dog.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Gentle and less excitable than most terriers indoors; game and determined at work.

Reward-based training from the day the puppy arrives, with the socialisation window (roughly three to sixteen weeks) treated as the priority it is — what happens in those weeks shapes the adult dog more than anything you do later. Short, frequent, positive sessions. See Parts IV and IX.

• Progressive retinal atrophy — Ophthalmologist eye examination, plus DNA test where one exists for the breed

Feeding

The most forgiving size to feed. A good-quality complete diet appropriate to the life stage, measured with a cup or scales rather than judged by eye, split into two meals a day. Weigh the food; guessing is how dogs get fat. Treats counted within the daily allowance, not added on top.

Exercise and enrichment

Stated requirement: Moderate - 45 min/day.

Moderate daily exercise plus mental stimulation. Adaptable to apartment life provided the daily walk actually happens every day.

Climate and living conditions

• Consider adoption. Shelters and rescues have dogs of every kind, including purebreds, and the local native or landrace dog is often healthier, better adapted to its climate, and more in need of a home than almost anything you can buy. See Part XII.

Jack Russell Terrier

Origin and purpose

Terrier (AKC recognises the Parson Russell subgroup). Origin: England, 19th century.

Not recommended alongside cats or small pets. Under-exercised dogs tend toward excessive barking.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Fearless, energetic, high prey drive, strong personality; not a cuddle dog.

Reward-based training from the day the puppy arrives, with the socialisation window (roughly three to sixteen weeks) treated as the priority it is — what happens in those weeks shapes the adult dog more than anything you do later. Short, frequent, positive sessions. See Parts IV and IX.

Strong prey drive: this dog may chase cats, poultry, and small animals, and may pursue free-roaming dogs or livestock. That is instinct, not disobedience, and it is largely not trainable out. Manage it with a secure garden, a lead near roads and livestock, and a realistic view of what recall can achieve against a moving target.

Health — what this breed is predisposed to

Drawn from this breed's documented health issues and cross-referenced to Part III. A predisposition is not a prophecy — most dogs of any breed never develop these — but it is what you and your vet should be watching for.

• Congenital deafness (Routine) — Present from birth and permanent.
• Legg-Calvé-Perthes disease (Routine) — femoral head necrosis in small breeds (Toy, terriers).
• Patellar luxation (Routine) — kneecap slips out of groove.

Health screening — what to test, and when

Derived from the predispositions above. Take this list to your vet; it is a starting point for a conversation, not a prescription, and your vet may reasonably add to it or leave items out for your dog.

Every dog, every breed: an annual health examination (twice yearly from seven years), body-condition scoring at each visit, dental assessment, year-round parasite control, and the core vaccinations.

Vaccination is NOT breed-specific, and any source that claims a breed-specific vaccination schedule should be treated with suspicion. The core schedule — the puppy series and its boosters, and rabies above all — is the same for this dog as for every other, and is set out in Parts VI and IX. What IS specific to the dog is its exposure: a dog that swims, roams, or lives where monsoon flooding occurs has a different leptospirosis risk from an apartment dog, and a dog that boards or meets many other dogs has a different kennel-cough risk. Discuss the dog's actual life with your vet, not its breed.

For breeders — test before you mate

The heritable subset of the screening above. These are the tests a responsible breeder of this breed completes BEFORE a mating, and the results a buyer is entitled to ask to see. A breeder who cannot produce them is telling you something. See Part XII.

• Congenital deafness — BAER hearing test
• Legg-Calvé-Perthes disease — Hip radiographs
• Patellar luxation — Patellar palpation by a vet

Feeding

Small stomachs, fast metabolisms. Feed a diet formulated for small breeds, split across three or four meals a day as a puppy and two as an adult; toy puppies can become dangerously hypoglycaemic if a meal is missed. Portions are tiny, which means treats and table scraps overwhelm the daily allowance startlingly fast — a single biscuit can be a meaningful share of a 4 kg dog's intake. Dental disease is near-universal in small breeds, so ask your vet about diet texture and dental care from the start.

Exercise and enrichment

Stated requirement: High — 60+ min/day.

A high-energy dog needing substantial, committed daily exercise plus mental work. Do not take this breed on unless the daily commitment is realistic on your worst week, not your best one.

Coat and grooming

Smooth, broken, or rough coat. Weekly brush; strip the rough coat occasionally.

Climate and living conditions

Stated suitability: Excellent size for apartment living; management-intensive..

This breed is well adapted to hot climates — which is one of the strongest practical arguments for it. It still needs shade, unlimited fresh water, and walks outside the hottest hours, but it is not fighting its own biology to live here.

Ageing and senior care

Life expectancy: 13–16 years. This dog is a senior from around 9–10 years, at which point wellness examinations should move to twice a year and senior blood and urine screening begins. Small dogs age slowly and often live into their mid-teens. Dental disease and heart-valve disease are the two things that most often shorten a small dog's life, and both are catchable early. See Part X.

Jagdterrier (German Hunting Terrier)

Origin and purpose

FCI Group 3 (Section 1); not AKC (UKC-recognised). Origin: Germany; versatile below- and above-ground hunting terrier.

Bred for gameness in the early 20th century; a specialist hunting terrier.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Extremely bold, driven and hard; a serious working hunter, not a casual pet.

Reward-based training from the day the puppy arrives, with the socialisation window (roughly three to sixteen weeks) treated as the priority it is — what happens in those weeks shapes the adult dog more than anything you do later. Short, frequent, positive sessions. See Parts IV and IX.

Health — what this breed is predisposed to

No breed-linked conditions are recorded for this breed. For landraces and village dogs this is often a genuine finding rather than a gap — a broad genetic base leaves them with markedly fewer inherited disorders than the closed-studbook breeds, and it is one of the strongest arguments for them. The routine risks that apply to every dog — parasites, tick-borne disease, heat — still apply here.

Every dog, every breed: an annual health examination (twice yearly from seven years), body-condition scoring at each visit, dental assessment, year-round parasite control, and the core vaccinations.

Vaccination is NOT breed-specific, and any source that claims a breed-specific vaccination schedule should be treated with suspicion. The core schedule — the puppy series and its boosters, and rabies above all — is the same for this dog as for every other, and is set out in Parts VI and IX.

Portions are tiny, which means treats and table scraps overwhelm the daily allowance startlingly fast — a single biscuit can be a meaningful share of a 4 kg dog's intake. Dental disease is near-universal in small breeds, so ask your vet about diet texture and dental care from the start.

Exercise and enrichment

Stated requirement: Very high - 60+ min/day plus real work.

This is a genuinely high-energy dog and the commonest reason such dogs are rehomed is that their owners underestimated this. It needs hard daily physical exercise AND a job to think about; a walk around the block is not exercise for this breed. An under-exercised dog of this type becomes destructive, noisy, and anxious — behaviour problems that are, correctly understood, an exercise deficit.

Climate and living conditions

Stated suitability: Good for warm climates - the dense harsh or smooth coat tolerates heat; it must have a working outlet and is not a flat companion..

Ageing and senior care

Life expectancy: 12-15 years. This dog is a senior from around 9–10 years, at which point wellness examinations should move to twice a year and senior blood and urine screening begins. Small dogs age slowly and often live into their mid-teens. Dental disease and heart-valve disease are the two things that most often shorten a small dog's life, and both are catchable early. See Part X.

Kerry Blue Terrier

Origin and purpose

Terrier (AKC); FCI Group 3. Origin: Ireland (County Kerry); all-round farm, vermin and herding terrier.

Born black, the coat matures to blue-grey by around 18 months.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Spirited, intelligent and alert; devoted to family but can be dog-aggressive.

Reward-based training from the day the puppy arrives, with the socialisation window (roughly three to sixteen weeks) treated as the priority it is — what happens in those weeks shapes the adult dog more than anything you do later. Short, frequent, positive sessions. See Parts IV and IX.

Health — what this breed is predisposed to

Drawn from this breed's documented health issues and cross-referenced to Part III. A predisposition is not a prophecy — most dogs of any breed never develop these — but it is what you and your vet should be watching for.

• Entropion (Routine) — eyelid rolls inward.
• Hip dysplasia (Routine) — abnormal hip joint development.
• Hypothyroidism (Routine) — underactive thyroid.

Health screening — what to test, and when

Derived from the predispositions above. Take this list to your vet; it is a starting point for a conversation, not a prescription, and your vet may reasonably add to it or leave items out for your dog.

Every dog, every breed: an annual health examination (twice yearly from seven years), body-condition scoring at each visit, dental assessment, year-round parasite control, and the core vaccinations.

• Entropion — Eye examination
• Hip dysplasia — Radiographic hip evaluation (hip scoring)
• Hypothyroidism — Thyroid blood panel

Feeding

The most forgiving size to feed. A good-quality complete diet appropriate to the life stage, measured with a cup or scales rather than judged by eye, split into two meals a day. Weigh the food; guessing is how dogs get fat. Treats counted within the daily allowance, not added on top.

Exercise and enrichment

Stated requirement: High - 60+ min/day.

A high-energy dog needing substantial, committed daily exercise plus mental work. Do not take this breed on unless the daily commitment is realistic on your worst week, not your best one.

Climate and living conditions

Stated suitability: Moderate - the soft non-shedding coat is low-dander but requires frequent clipping; keep the dog cool in hot weather..

Ageing and senior care

Life expectancy: 12-15 years. This dog is a senior from around 8–9 years, at which point wellness examinations should move to twice a year and senior blood and urine screening begins. Watch for the gradual onset of arthritis, dental disease, and the endocrine conditions of middle age. See Part X.

Lakeland Terrier

Origin and purpose

Terrier (AKC); FCI Group 3. Origin: England (Lake District); fox terrier for fell country.

One of the oldest working terrier breeds, bred to bolt foxes from rocky dens.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Manchester Terrier

Origin and purpose

Terrier (AKC); FCI Group 3. Origin: England (Manchester); ratting and rabbit-coursing terrier.

Black-and-tan; comes in Standard and Toy varieties, judged as one breed by the AKC.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Miniature Bull Terrier

Origin and purpose

Terrier (AKC); FCI Group 3. Origin: England; downsized companion of the Bull Terrier.

Same distinctive egg-shaped head as the standard Bull Terrier, in a smaller frame.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Miniature Schnauzer

Origin and purpose

Terrier (AKC). Origin: Germany.

A low-fat diet is often recommended by vets due to pancreatitis predisposition.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Alert, intelligent, spirited.

Reward-based training from the day the puppy arrives, with the socialisation window (roughly three to sixteen weeks) treated as the priority it is — what happens in those weeks shapes the adult dog more than anything you do later. Short, frequent, positive sessions. See Parts IV and IX.

Health — what this breed is predisposed to

Drawn from this breed's documented health issues and cross-referenced to Part III. A predisposition is not a prophecy — most dogs of any breed never develop these — but it is what you and your vet should be watching for.

• Pancreatitis (URGENT) — inflammation of the pancreas.
• Cataracts (Routine) — congenital or diabetic or senior.
• Hyperlipidaemia (Routine) — Miniature Schnauzer predisposed.
• Progressive retinal atrophy (Routine) — genetic retinal degeneration.

Health screening — what to test, and when

Derived from the predispositions above. Take this list to your vet; it is a starting point for a conversation, not a prescription, and your vet may reasonably add to it or leave items out for your dog.

Every dog, every breed: an annual health examination (twice yearly from seven years), body-condition scoring at each visit, dental assessment, year-round parasite control, and the core vaccinations.

Vaccination is NOT breed-specific, and any source that claims a breed-specific vaccination schedule should be treated with suspicion. The core schedule — the puppy series and its boosters, and rabies above all — is the same for this dog as for every other, and is set out in Parts VI and IX.

For breeders — test before you mate

The heritable subset of the screening above. These are the tests a responsible breeder of this breed completes BEFORE a mating, and the results a buyer is entitled to ask to see. A breeder who cannot produce them is telling you something. See Part XII.

• Cataracts — Ophthalmologist eye examination
• Progressive retinal atrophy — Ophthalmologist eye examination, plus DNA test where one exists for the breed

Feeding

Small stomachs, fast metabolisms. Feed a diet formulated for small breeds, split across three or four meals a day as a puppy and two as an adult; toy puppies can become dangerously hypoglycaemic if a meal is missed. Portions are tiny, which means treats and table scraps overwhelm the daily allowance startlingly fast — a single biscuit can be a meaningful share of a 4 kg dog's intake. Dental disease is near-universal in small breeds, so ask your vet about diet texture and dental care from the start.

Exercise and enrichment

Stated requirement: Moderate — 45 min/day.

Moderate daily exercise plus mental stimulation. Adaptable to apartment life provided the daily walk actually happens every day.

Coat and grooming

Harsh, wiry double coat. Brush 2–3× weekly; clip every 6–8 weeks; keep the beard clean and dry.

Climate and living conditions

Stated suitability: Good for apartments..

This breed carries a heavy double coat evolved for cold. It can be kept in a hot climate, but only with genuine commitment: shade and water at all times, exercise confined to the cool hours, and often air-conditioning through summer. Do NOT shave the double coat — counter-intuitively it insulates against heat as well as cold, and shaving it can ruin the coat and expose the skin to sunburn. Watch closely for heat stress, and think hard about whether the climate you live in is fair to this dog before acquiring one.

Ageing and senior care

Life expectancy: 12–15 years. This dog is a senior from around 9–10 years, at which point wellness examinations should move to twice a year and senior blood and urine screening begins. Small dogs age slowly and often live into their mid-teens. Dental disease and heart-valve disease are the two things that most often shorten a small dog's life, and both are catchable early. See Part X.

Norfolk Terrier

Origin and purpose

Terrier (AKC). Origin: England.

One of the smallest terriers, distinguished from the Norwich by its drop ears.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Fearless, alert, sociable; drop-ear cousin of the Norwich.

Reward-based training from the day the puppy arrives, with the socialisation window (roughly three to sixteen weeks) treated as the priority it is — what happens in those weeks shapes the adult dog more than anything you do later. Short, frequent, positive sessions. See Parts IV and IX.

Health — what this breed is predisposed to

Drawn from this breed's documented health issues and cross-referenced to Part III. A predisposition is not a prophecy — most dogs of any breed never develop these — but it is what you and your vet should be watching for.

• Hip dysplasia (Routine) — abnormal hip joint development.
• Mitral valve disease (Routine) — degenerative valve disease; most common in senior small breeds (Cavalier King Charles, Dachshund, Chihuahua).
• Patellar luxation (Routine) — kneecap slips out of groove.

Health screening — what to test, and when

Derived from the predispositions above. Take this list to your vet; it is a starting point for a conversation, not a prescription, and your vet may reasonably add to it or leave items out for your dog.

Every dog, every breed: an annual health examination (twice yearly from seven years), body-condition scoring at each visit, dental assessment, year-round parasite control, and the core vaccinations.

Vaccination is NOT breed-specific, and any source that claims a breed-specific vaccination schedule should be treated with suspicion. The core schedule — the puppy series and its boosters, and rabies above all — is the same for this dog as for every other, and is set out in Parts VI and IX. What IS specific to the dog is its exposure: a dog that swims, roams, or lives where monsoon flooding occurs has a different leptospirosis risk from an apartment dog, and a dog that boards or meets many other dogs has a different kennel-cough risk. Discuss the dog's actual life with your vet, not its breed.

For breeders — test before you mate

The heritable subset of the screening above. These are the tests a responsible breeder of this breed completes BEFORE a mating, and the results a buyer is entitled to ask to see. A breeder who cannot produce them is telling you something. See Part XII.

• Hip dysplasia — Radiographic hip evaluation (hip scoring)
• Mitral valve disease — Cardiac auscultation; echocardiography once a murmur is heard
• Patellar luxation — Patellar palpation by a vet

Feeding

Small stomachs, fast metabolisms. Feed a diet formulated for small breeds, split across three or four meals a day as a puppy and two as an adult; toy puppies can become dangerously hypoglycaemic if a meal is missed. Portions are tiny, which means treats and table scraps overwhelm the daily allowance startlingly fast — a single biscuit can be a meaningful share of a 4 kg dog's intake. Dental disease is near-universal in small breeds, so ask your vet about diet texture and dental care from the start.

Exercise and enrichment

Stated requirement: Moderate.

Moderate daily exercise plus mental stimulation. Adaptable to apartment life provided the daily walk actually happens every day.

Climate and living conditions

Stated suitability: Good heat tolerance; well suited to apartment living..

Ageing and senior care

Life expectancy: 12–16 years. This dog is a senior from around 9–10 years, at which point wellness examinations should move to twice a year and senior blood and urine screening begins. Small dogs age slowly and often live into their mid-teens. Dental disease and heart-valve disease are the two things that most often shorten a small dog's life, and both are catchable early. See Part X.

Before you take one home

• Ask the breeder for the health-test results listed above — for BOTH parents, on paper, before you pay a deposit. A breeder who has done the tests will be proud to show you; one who deflects, or who tells you the tests are unnecessary in this line, is telling you what you need to know.
• Consider adoption. Shelters and rescues have dogs of every kind, including purebreds, and the local native or landrace dog is often healthier, better adapted to its climate, and more in need of a home than almost anything you can buy. See Part XII.

Norwich Terrier

Origin and purpose

Terrier (AKC). Origin: England.

One of the smallest terriers; its ears are erect, unlike the Norfolk's drop ears.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Alert, energetic, affectionate; erect-ear cousin of the Norfolk.

Reward-based training from the day the puppy arrives, with the socialisation window (roughly three to sixteen weeks) treated as the priority it is — what happens in those weeks shapes the adult dog more than anything you do later. Short, frequent, positive sessions. See Parts IV and IX.

Parson Russell Terrier

Origin and purpose

Terrier (AKC); FCI Group 3. Origin: England; fox-bolting terrier bred by Rev. John Russell.

The longer-legged, squarer standardised cousin of the Jack Russell Terrier.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Bold, energetic and clever; a tireless working terrier that needs an outlet.

Reward-based training from the day the puppy arrives, with the socialisation window (roughly three to sixteen weeks) treated as the priority it is — what happens in those weeks shapes the adult dog more than anything you do later. Short, frequent, positive sessions. See Parts IV and IX.

Health — what this breed is predisposed to

Drawn from this breed's documented health issues and cross-referenced to Part III. A predisposition is not a prophecy — most dogs of any breed never develop these — but it is what you and your vet should be watching for.

• Congenital deafness (Routine) — Present from birth and permanent.

• Congenital deafness — BAER hearing test
• Patellar luxation — Patellar palpation by a vet

Feeding

Small stomachs, fast metabolisms.

Dental disease is near-universal in small breeds, so ask your vet about diet texture and dental care from the start.

Exercise and enrichment

Stated requirement: High - 60+ min/day.

A high-energy dog needing substantial, committed daily exercise plus mental work. Do not take this breed on unless the daily commitment is realistic on your worst week, not your best one.

Climate and living conditions

Stated suitability: Good for warm climates - the short smooth or broken coat tolerates heat; needs vigorous daily exercise..

Ageing and senior care

Life expectancy: 13-15 years. This dog is a senior from around 9–10 years, at which point wellness examinations should move to twice a year and senior blood and urine screening begins.

Plummer Terrier

Origin and purpose

Working terrier (not FCI/AKC-recognised); UK Plummer Terrier registries. Origin: England; ratting and rabbiting terrier developed by Brian Plummer.

A recent (20th-century) working strain; not yet a fully standardised kennel-club breed.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Keen, bold and driven; an intense, high-prey-drive working terrier.

Reward-based training from the day the puppy arrives, with the socialisation window (roughly three to sixteen weeks) treated as the priority it is — what happens in those weeks shapes the adult dog more than anything you do later. Short, frequent, positive sessions. See Parts IV and IX.

Rat Terrier

Origin and purpose

Terrier (AKC); not FCI-recognised. Origin: United States; farm ratting and all-purpose vermin terrier.

Reputedly a favourite of President Theodore Roosevelt; comes in two size varieties.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Alert, active and affectionate; a clever, biddable farm terrier that bonds closely.

This is a biddable breed that wants to work with you, which makes it forgiving of a novice's mistakes — but biddability is not the same as needing no training. Reward-based training, started early and kept short and frequent, is what these dogs thrive on. Punishment-based methods damage exactly the willingness that makes the breed easy.

Health — what this breed is predisposed to

Drawn from this breed's documented health issues and cross-referenced to Part III. A predisposition is not a prophecy — most dogs of any breed never develop these — but it is what you and your vet should be watching for.

Exercise and enrichment

Stated requirement: Moderate-High - 45-60 min/day.

A high-energy dog needing substantial, committed daily exercise plus mental work. Do not take this breed on unless the daily commitment is realistic on your worst week, not your best one.

Climate and living conditions

Stated suitability: Good for warm climates - the short smooth coat suits heat; provide shade and water..

Ageing and senior care

Scottish Terrier (Scottie)

Origin and purpose

Terrier (AKC). Origin: Scotland.

Prone to an elevated risk of bladder cancer (transitional cell carcinoma).

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Independent, alert, dignified — classic Scotty temperament.

This is an independent-minded breed that was developed to make its own decisions, and it will not work for you simply because you asked. That is not stubbornness or stupidity — it is the trait the breed was selected for. Training must be genuinely rewarding to the dog, and expectations of instant, military obedience are misplaced. Recall, in particular, is often unreliable in these breeds; be honest about that before letting one off-lead near traffic.

Health — what this breed is predisposed to

Drawn from this breed's documented health issues and cross-referenced to Part III. A predisposition is not a prophecy — most dogs of any breed never develop these — but it is what you and your vet should be watching for.

• Transitional cell carcinoma (URGENT) — bladder.
• von Willebrand disease (Routine) — The most common inherited bleeding disorder of dogs: a deficiency of von Willebrand factor, a protein needed for platelets to plug a damaged vessel.

Health screening — what to test, and when

Derived from the predispositions above. Take this list to your vet; it is a starting point for a conversation, not a prescription, and your vet may reasonably add to it or leave items out for your dog.

Every dog, every breed: an annual health examination (twice yearly from seven years), body-condition scoring at each visit, dental assessment, year-round parasite control, and the core vaccinations.

Vaccination is NOT breed-specific, and any source that claims a breed-specific vaccination schedule should be treated with suspicion. The core schedule — the puppy series and its boosters, and rabies above all — is the same for this dog as for every other, and is set out in Parts VI and IX. What IS specific to the dog is its exposure: a dog that swims, roams, or lives where monsoon flooding occurs has a different leptospirosis risk from an apartment dog, and a dog that boards or meets many other dogs has a different kennel-cough risk. Discuss the dog's actual life with your vet, not its breed.

For breeders — test before you mate

The heritable subset of the screening above. These are the tests a responsible breeder of this breed completes BEFORE a mating, and the results a buyer is entitled to ask to see. A breeder who cannot produce them is telling you something. See Part XII.

• von Willebrand disease — von Willebrand factor blood assay, or DNA test

Feeding

Small stomachs, fast metabolisms. Feed a diet formulated for small breeds, split across three or four meals a day as a puppy and two as an adult; toy puppies can become dangerously hypoglycaemic if a meal is missed. Portions are tiny, which means treats and table scraps overwhelm the daily allowance startlingly fast — a single biscuit can be a meaningful share of a 4 kg dog's intake. Dental disease is near-universal in small breeds, so ask your vet about diet texture and dental care from the start.

Exercise and enrichment

Stated requirement: Moderate.

Moderate daily exercise plus mental stimulation. Adaptable to apartment life provided the daily walk actually happens every day.

Climate and living conditions

Stated suitability: Good heat tolerance; well suited to apartment living..

Ageing and senior care

Life expectancy: 11–13 years. This dog is a senior from around 9–10 years, at which point wellness examinations should move to twice a year and senior blood and urine screening begins. Small dogs age slowly and often live into their mid-teens. Dental disease and heart-valve disease are the two things that most often shorten a small dog's life, and both are catchable early. See Part X.

Before you take one home

• Ask the breeder for the health-test results listed above — for BOTH parents, on paper, before you pay a deposit. A breeder who has done the tests will be proud to show you; one who deflects, or who tells you the tests are unnecessary in this line, is telling you what you need to know.
• Consider adoption. Shelters and rescues have dogs of every kind, including purebreds, and the local native or landrace dog is often healthier, better adapted to its climate, and more in need of a home than almost anything you can buy. See Part XII.

Sealyham Terrier

Origin and purpose

Terrier (AKC); FCI Group 3. Origin: Wales (Pembrokeshire); badger, otter and fox terrier.

One of the rarer terriers, listed as vulnerable by the UK Kennel Club.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Calm and good-humoured for a terrier, but bold and independent-minded.

This is an independent-minded breed that was developed to make its own decisions, and it will not work for you simply because you asked. That is not stubbornness or stupidity — it is the trait the breed was selected for. Training must be genuinely rewarding to the dog, and expectations of instant, military obedience are misplaced. Recall, in particular, is often unreliable in these breeds; be honest about that before letting one off-lead near traffic.

Health — what this breed is predisposed to

Drawn from this breed's documented health issues and cross-referenced to Part III. A predisposition is not a prophecy — most dogs of any breed never develop these — but it is what you and your vet should be watching for.

• Atopic dermatitis (canine atopy) (Routine) — allergic skin disease.

Health screening — what to test, and when

Derived from the predispositions above. Take this list to your vet; it is a starting point for a conversation, not a prescription, and your vet may reasonably add to it or leave items out for your dog.

Every dog, every breed: an annual health examination (twice yearly from seven years), body-condition scoring at each visit, dental assessment, year-round parasite control, and the core vaccinations.

Vaccination is NOT breed-specific, and any source that claims a breed-specific vaccination schedule should be treated with suspicion. The core schedule — the puppy series and its boosters, and rabies above all — is the same for this dog as for every other, and is set out in Parts VI and IX. What IS specific to the dog is its exposure: a dog that swims, roams, or lives where monsoon flooding occurs has a different leptospirosis risk from an apartment dog, and a dog that boards or meets many other dogs has a different kennel-cough risk. Discuss the dog's actual life with your vet, not its breed.

For breeders — test before you mate

The heritable subset of the screening above. These are the tests a responsible breeder of this breed completes BEFORE a mating, and the results a buyer is entitled to ask to see. A breeder who cannot produce them is telling you something. See Part XII.

• Atopic dermatitis (canine atopy) — No screening test; allergy testing once disease is established

Feeding

Small stomachs, fast metabolisms. Feed a diet formulated for small breeds, split across three or four meals a day as a puppy and two as an adult; toy puppies can become dangerously hypoglycaemic if a meal is missed. Portions are tiny, which means treats and table scraps overwhelm the daily allowance startlingly fast — a single biscuit can be a meaningful share of a 4 kg dog's intake. Dental disease is near-universal in small breeds, so ask your vet about diet texture and dental care from the start.

Exercise and enrichment

Stated requirement: Moderate - 30-45 min/day.

Moderate daily exercise plus mental stimulation. Adaptable to apartment life provided the daily walk actually happens every day.

Climate and living conditions

Stated suitability: Moderate - the dense weather-resistant coat needs hand-stripping or clipping and should be kept cool in hot weather..

Ageing and senior care

Life expectancy: 12-14 years. This dog is a senior from around 9–10 years, at which point wellness examinations should move to twice a year and senior blood and urine screening begins. Small dogs age slowly and often live into their mid-teens. Dental disease and heart-valve disease are the two things that most often shorten a small dog's life, and both are catchable early. See Part X.

Before you take one home

• Ask the breeder for the health-test results listed above — for BOTH parents, on paper, before you pay a deposit. A breeder who has done the tests will be proud to show you; one who deflects, or who tells you the tests are unnecessary in this line, is telling you what you need to know.
• Consider adoption. Shelters and rescues have dogs of every kind, including purebreds, and the local native or landrace dog is often healthier, better adapted to its climate, and more in need of a home than almost anything you can buy. See Part XII.

Skye Terrier

Origin and purpose

Terrier (AKC); FCI Group 3. Origin: Scotland (Isle of Skye); fox and badger terrier.

Long-bodied, low-set; a vulnerable native breed with very low registration numbers.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Loyal and reserved with strangers, deeply devoted to its person; dignified and sensitive.

Reward-based training from the day the puppy arrives, with the socialisation window (roughly three to sixteen weeks) treated as the priority it is — what happens in those weeks shapes the adult dog more than anything you do later. Short, frequent, positive sessions. See Parts IV and IX.

Health — what this breed is predisposed to

Drawn from this breed's documented health issues and cross-referenced to Part III. A predisposition is not a prophecy — most dogs of any breed never develop these — but it is what you and your vet should be watching for.

• Intervertebral disc disease (IVDD) (EMERGENCY) — disc herniation.

Health screening — what to test, and when

Derived from the predispositions above. Take this list to your vet; it is a starting point for a conversation, not a prescription, and your vet may reasonably add to it or leave items out for your dog.

Every dog, every breed: an annual health examination (twice yearly from seven years), body-condition scoring at each visit, dental assessment, year-round parasite control, and the core vaccinations.

• Intervertebral disc disease (IVDD) — DNA test for the chondrodystrophy variant; imaging if signs appear

Feeding

The most forgiving size to feed. A good-quality complete diet appropriate to the life stage, measured with a cup or scales rather than judged by eye, split into two meals a day. Weigh the food; guessing is how dogs get fat. Treats counted within the daily allowance, not added on top.

Exercise and enrichment

Stated requirement: Moderate - 30-45 min/day; protect the long back from jumping.

Moderate daily exercise plus mental stimulation. Adaptable to apartment life provided the daily walk actually happens every day.

Climate and living conditions

Stated suitability: Poor to moderate in heat - the long profuse double coat is heat-retentive and demands heavy grooming; better in cooler conditions..

Ageing and senior care

Life expectancy: 12-14 years. This dog is a senior from around 8–9 years, at which point wellness examinations should move to twice a year and senior blood and urine screening begins. Watch for the gradual onset of arthritis, dental disease, and the endocrine conditions of middle age. See Part X.

Smooth Fox Terrier

Origin and purpose

Terrier (AKC); FCI Group 3. Origin: England; fox-bolting and vermin terrier.

The smooth-coated counterpart to the Wire Fox Terrier, judged as a separate breed.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Bold, lively and outgoing; a confident, high-energy terrier full of character.

Reward-based training from the day the puppy arrives, with the socialisation window (roughly three to sixteen weeks) treated as the priority it is — what happens in those weeks shapes the adult dog more than anything you do later. Short, frequent, positive sessions. See Parts IV and IX.

Health — what this breed is predisposed to

Drawn from this breed's documented health issues and cross-referenced to Part III. A predisposition is not a prophecy — most dogs of any breed never develop these — but it is what you and your vet should be watching for.

• Congenital deafness (Routine) — Present from birth and permanent.
• Legg-Calvé-Perthes disease (Routine) — femoral head necrosis in small breeds (Toy, terriers).
• Patellar luxation (Routine) — kneecap slips out of groove.

Health screening — what to test, and when

Derived from the predispositions above. Take this list to your vet; it is a starting point for a conversation, not a prescription, and your vet may reasonably add to it or leave items out for your dog.

Every dog, every breed: an annual health examination (twice yearly from seven years), body-condition scoring at each visit, dental assessment, year-round parasite control, and the core vaccinations.

• Congenital deafness — BAER hearing test
• Legg-Calvé-Perthes disease — Hip radiographs
• Patellar luxation — Patellar palpation by a vet

Feeding

Small stomachs, fast metabolisms. Feed a diet formulated for small breeds, split across three or four meals a day as a puppy and two as an adult; toy puppies can become dangerously hypoglycaemic if a meal is missed. Portions are tiny, which means treats and table scraps overwhelm the daily allowance startlingly fast — a single biscuit can be a meaningful share of a 4 kg dog's intake. Dental disease is near-universal in small breeds, so ask your vet about diet texture and dental care from the start.

Exercise and enrichment

Stated requirement: High - 60 min/day.

A high-energy dog needing substantial, committed daily exercise plus mental work. Do not take this breed on unless the daily commitment is realistic on your worst week, not your best one.

Climate and living conditions

Stated suitability: Good for warm climates - the short flat coat is easy-care and heat-tolerant; needs vigorous daily exercise..

This breed is well adapted to hot climates — which is one of the strongest practical arguments for it. It still needs shade, unlimited fresh water, and walks outside the hottest hours, but it is not fighting its own biology to live here.

Ageing and senior care

Life expectancy: 12-15 years. This dog is a senior from around 9–10 years, at which point wellness examinations should move to twice a year and senior blood and urine screening begins. Small dogs age slowly and often live into their mid-teens. Dental disease and heart-valve disease are the two things that most often shorten a small dog's life, and both are catchable early.

Soft-Coated Wheaten Terrier

Origin and purpose

Terrier (AKC). Origin: Ireland.

The soft, silky coat requires committed care.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Happy, adaptable, playful; softer than typical terrier.

Reward-based training from the day the puppy arrives, with the socialisation window (roughly three to sixteen weeks) treated as the priority it is — what happens in those weeks shapes the adult dog more than anything you do later. Short, frequent, positive sessions. See Parts IV and IX.

Health — what this breed is predisposed to

Drawn from this breed's documented health issues and cross-referenced to Part III. A predisposition is not a prophecy — most dogs of any breed never develop these — but it is what you and your vet should be watching for.

A high-energy dog needing substantial, committed daily exercise plus mental work. Do not take this breed on unless the daily commitment is realistic on your worst week, not your best one.

Climate and living conditions

Stated suitability: Moderate heat tolerance; grooming is intensive..

Ageing and senior care

Sporting Lucas Terrier

Origin and purpose

Working/companion terrier (UK Kennel Club-recorded; not FCI/AKC). Origin: England; rabbiting and companion terrier.

Developed from the older Lucas Terrier; recorded on the UK Kennel Club's imported register.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Friendly, biddable and less scrappy than many terriers; a sociable working companion.

This is a biddable breed that wants to work with you, which makes it forgiving of a novice's mistakes — but biddability is not the same as needing no training. Reward-based training, started early and kept short and frequent, is what these dogs thrive on. Punishment-based methods damage exactly the willingness that makes the breed easy.

Health — what this breed is predisposed to

Drawn from this breed's documented health issues and cross-referenced to Part III. A predisposition is not a prophecy — most dogs of any breed never develop these — but it is what you and your vet should be watching for.

Small stomachs, fast metabolisms. Feed a diet formulated for small breeds, split across three or four meals a day as a puppy and two as an adult; toy puppies can become dangerously hypoglycaemic if a meal is missed. Portions are tiny, which means treats and table scraps overwhelm the daily allowance startlingly fast — a single biscuit can be a meaningful share of a 4 kg dog's intake.

Exercise and enrichment

Stated requirement: Moderate - 45 min/day.

Moderate daily exercise plus mental stimulation. Adaptable to apartment life provided the daily walk actually happens every day.

Climate and living conditions

Stated suitability: Moderate and adaptable - the harsh medium coat needs occasional stripping; an adaptable small companion in most climates..

Ageing and senior care

Life expectancy: 12-15 years. This dog is a senior from around 9–10 years, at which point wellness examinations should move to twice a year and senior blood and urine screening begins.

Staffordshire Bull Terrier

Origin and purpose

Terrier (AKC). Origin: England (Staffordshire).

Historically known as the 'nanny dog' in England; breed-specific legislation restricts ownership in some jurisdictions, so check local regulations.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Affectionate, courageous, family-loyal; misunderstood breed.

Reward-based training from the day the puppy arrives, with the socialisation window (roughly three to sixteen weeks) treated as the priority it is — what happens in those weeks shapes the adult dog more than anything you do later. Short, frequent, positive sessions. See Parts IV and IX.

Health — what this breed is predisposed to

Drawn from this breed's documented health issues and cross-referenced to Part III. A predisposition is not a prophecy — most dogs of any breed never develop these — but it is what you and your vet should be watching for.

• Cataracts (Routine) — congenital or diabetic or senior.
• Hip dysplasia (Routine) — abnormal hip joint development.

Health screening — what to test, and when

Derived from the predispositions above. Take this list to your vet; it is a starting point for a conversation, not a prescription, and your vet may reasonably add to it or leave items out for your dog.

Every dog, every breed: an annual health examination (twice yearly from seven years), body-condition scoring at each visit, dental assessment, year-round parasite control, and the core vaccinations.

Vaccination is NOT breed-specific, and any source that claims a breed-specific vaccination schedule should be treated with suspicion. The core schedule — the puppy series and its boosters, and rabies above all — is the same for this dog as for every other, and is set out in Parts VI and IX.

• Cataracts — Ophthalmologist eye examination
• Hip dysplasia — Radiographic hip evaluation (hip scoring)

Feeding

The most forgiving size to feed. A good-quality complete diet appropriate to the life stage, measured with a cup or scales rather than judged by eye, split into two meals a day. Weigh the food; guessing is how dogs get fat. Treats counted within the daily allowance, not added on top.

Exercise and enrichment

Stated requirement: High.

A high-energy dog needing substantial, committed daily exercise plus mental work. Do not take this breed on unless the daily commitment is realistic on your worst week, not your best one.

Coat and grooming

Very short, smooth coat. Weekly rub-down.

Climate and living conditions

Stated suitability: Moderate heat tolerance; a committed handler is required in any climate..

HEAT IS THE DEFINING WELFARE ISSUE FOR THIS BREED IN ANY HOT CLIMATE. A short skull means a compromised airway, and dogs cool themselves by panting — so this dog cannot cool itself efficiently, and heat and humidity are therefore genuinely dangerous to it rather than merely uncomfortable. Walk only at dawn and dusk, never on hot ground, never in the midday sun, and never leave it in a vehicle even briefly. Keep it lean: excess weight makes the airway worse. Air-conditioning is not a luxury for this breed in a hot climate. Learn the signs of heatstroke (see Part III) and treat any laboured breathing in heat as an emergency. Airlines frequently refuse to carry these breeds, and they are right to.

Ageing and senior care

Life expectancy: 12–14 years. This dog is a senior from around 8–9 years, at which point wellness examinations should move to twice a year and senior blood and urine screening begins. Watch for the gradual onset of arthritis, dental disease, and the endocrine conditions of middle age. See Part X.

Before you take one home

• This is a short-skulled breed. Choose the puppy with the most open nostrils and the longest muzzle you can find, and reject any that snores, snorts, or struggles for breath at rest — those are not endearing breed traits, they are signs of a dog that cannot breathe properly. Ask whether the parents have been BOAS-graded. In a hot climate this decision has consequences you will live with daily.
• Consider adoption. Shelters and rescues have dogs of every kind, including purebreds, and the local native or landrace dog is often healthier, better adapted to its climate, and more in need of a home than almost anything you can buy. See Part XII.

Teddy Roosevelt Terrier

Origin and purpose

Terrier (UKC-recognised); not AKC/FCI. Origin: United States; short-legged farm ratting terrier.

A short-legged type separated from the Rat Terrier; recognised by the UKC.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

• Patellar luxation — Patellar palpation by a vet

Feeding

Small stomachs, fast metabolisms. Feed a diet formulated for small breeds, split across three or four meals a day as a puppy and two as an adult; toy puppies can become dangerously hypoglycaemic if a meal is missed. Portions are tiny, which means treats and table scraps overwhelm the daily allowance startlingly fast — a single biscuit can be a meaningful share of a 4 kg dog's intake. Dental disease is near-universal in small breeds, so ask your vet about diet texture and dental care from the start.

Exercise and enrichment

Stated requirement: Moderate - 30-45 min/day.

Moderate daily exercise plus mental stimulation. Adaptable to apartment life provided the daily walk actually happens every day.

Climate and living conditions

Stated suitability: Good for warm climates - the short smooth coat suits heat with shade provided..

Ageing and senior care

Life expectancy: 14-16 years. This dog is a senior from around 9–10 years, at which point wellness examinations should move to twice a year and senior blood and urine screening begins. Small dogs age slowly and often live into their mid-teens. Dental disease and heart-valve disease are the two things that most often shorten a small dog's life, and both are catchable early.

Resembles a smaller Airedale; a vulnerable native breed in the UK.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Friendly, spirited and even-tempered; a robust, cheerful terrier that trains well.

Reward-based training from the day the puppy arrives, with the socialisation window (roughly three to sixteen weeks) treated as the priority it is — what happens in those weeks shapes the adult dog more than anything you do later. Short, frequent, positive sessions. See Parts IV and IX.

Health — what this breed is predisposed to

Drawn from this breed's documented health issues and cross-referenced to Part III. A predisposition is not a prophecy — most dogs of any breed never develop these — but it is what you and your vet should be watching for.

• Glaucoma (URGENT) — elevated intraocular pressure.

Health screening — what to test, and when

Derived from the predispositions above. Take this list to your vet; it is a starting point for a conversation, not a prescription, and your vet may reasonably add to it or leave items out for your dog.

Every dog, every breed: an annual health examination (twice yearly from seven years), body-condition scoring at each visit, dental assessment, year-round parasite control, and the core vaccinations.

Vaccination is NOT breed-specific, and any source that claims a breed-specific vaccination schedule should be treated with suspicion. The core schedule — the puppy series and its boosters, and rabies above all — is the same for this dog as for every other, and is set out in Parts VI and IX. What IS specific to the dog is its exposure: a dog that swims, roams, or lives where monsoon flooding occurs has a different leptospirosis risk from an apartment dog, and a dog that boards or meets many other dogs has a different kennel-cough risk. Discuss the dog's actual life with your vet, not its breed.

For breeders — test before you mate

The heritable subset of the screening above. These are the tests a responsible breeder of this breed completes BEFORE a mating, and the results a buyer is entitled to ask to see. A breeder who cannot produce them is telling you something. See Part XII.

• Glaucoma — Eye-pressure measurement (tonometry); gonioscopy in predisposed breeds

Feeding

Small stomachs, fast metabolisms. Feed a diet formulated for small breeds, split across three or four meals a day as a puppy and two as an adult; toy puppies can become dangerously hypoglycaemic if a meal is missed. Portions are tiny, which means treats and table scraps overwhelm the daily allowance startlingly fast — a single biscuit can be a meaningful share of a 4 kg dog's intake. Dental disease is near-universal in small breeds, so ask your vet about diet texture and dental care from the start.

Exercise and enrichment

Stated requirement: Moderate-High - 45-60 min/day.

A high-energy dog needing substantial, committed daily exercise plus mental work. Do not take this breed on unless the daily commitment is realistic on your worst week, not your best one.

Climate and living conditions

Stated suitability: Moderate - the harsh wiry coat needs stripping; hardy and adaptable to warm climates with care, shade and hydration..

Ageing and senior care

Life expectancy: 12-15 years. This dog is a senior from around 9–10 years, at which point wellness examinations should move to twice a year and senior blood and urine screening begins. Small dogs age slowly and often live into their mid-teens. Dental disease and heart-valve disease are the two things that most often shorten a small dog's life, and both are catchable early. See Part X.

Before you take one home

• Ask the breeder for the health-test results listed above — for BOTH parents, on paper, before you pay a deposit. A breeder who has done the tests will be proud to show you; one who deflects, or who tells you the tests are unnecessary in this line, is telling you what you need to know.
• Consider adoption. Shelters and rescues have dogs of every kind, including purebreds, and the local native or landrace dog is often healthier, better adapted to its climate, and more in need of a home than almost anything you can buy. See Part XII.

DRAFT — VET REVIEW PENDING. The predispositions, screening schedule, and breeder tests above are derived from this breed's recorded health issues; the feeding, exercise, climate, training, and ageing guidance is derived from its size, skull shape, coat, and temperament. Both are drafts until a veterinarian signs them off (Appendix A.3).

West Highland White Terrier (Westie)

Origin and purpose

Terrier (AKC). Origin: Scotland.

The distinctive white coat is prone to allergic skin disease.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Bold, cheerful, self-assured.

Reward-based training from the day the puppy arrives, with the socialisation window (roughly three to sixteen weeks) treated as the priority it is — what happens in those weeks shapes the adult dog more than anything you do later. Short, frequent, positive sessions. See Parts IV and IX.

Health — what this breed is predisposed to

Drawn from this breed's documented health issues and cross-referenced to Part III. A predisposition is not a prophecy — most dogs of any breed never develop these — but it is what you and your vet should be watching for.

• Atopic dermatitis (canine atopy) (Routine) — allergic skin disease.
• Legg-Calvé-Perthes disease (Routine) — femoral head necrosis in small breeds (Toy, terriers).

Health screening — what to test, and when

Derived from the predispositions above. Take this list to your vet; it is a starting point for a conversation, not a prescription, and your vet may reasonably add to it or leave items out for your dog.

• Atopic dermatitis (canine atopy) — No screening test; allergy testing once disease is established
• Legg-Calvé-Perthes disease — Hip radiographs

Feeding

Small stomachs, fast metabolisms. Feed a diet formulated for small breeds, split across three or four meals a day as a puppy and two as an adult; toy puppies can become dangerously hypoglycaemic if a meal is missed. Portions are tiny, which means treats and table scraps overwhelm the daily allowance startlingly fast — a single biscuit can be a meaningful share of a 4 kg dog's intake. Dental disease is near-universal in small breeds, so ask your vet about diet texture and dental care from the start.

Exercise and enrichment

Stated requirement: Moderate.

Moderate daily exercise plus mental stimulation. Adaptable to apartment life provided the daily walk actually happens every day.

Climate and living conditions

Stated suitability: Good heat tolerance; well suited to apartment living..

Ageing and senior care

Life expectancy: 13–15 years. This dog is a senior from around 9–10 years, at which point wellness examinations should move to twice a year and senior blood and urine screening begins.

Yorkshire Terrier

Origin and purpose

Toy (AKC). Origin: England (Yorkshire).

Dental care from puppyhood is essential. Hypoglycaemia risk in small puppies means the feeding schedule matters.

What a breed was built to do explains most of what it will do in your home. A dog selected for hundreds of years to run, guard, herd, or hunt does not stop wanting to because it now lives in an apartment — the drive is the breed, and the job of the owner is to give it somewhere to go.

Temperament and training

Stated temperament: Bold, affectionate, big-dog attitude in a small package.

Reward-based training from the day the puppy arrives, with the socialisation window (roughly three to sixteen weeks) treated as the priority it is — what happens in those weeks shapes the adult dog more than anything you do later. Short, frequent, positive sessions. See Parts IV and IX.

Health — what this breed is predisposed to

Drawn from this breed's documented health issues and cross-referenced to Part III. A predisposition is not a prophecy — most dogs of any breed never develop these — but it is what you and your vet should be watching for.

• Juvenile hypoglycaemia (EMERGENCY) — toy-breed puppies.
• Portosystemic shunt (URGENT) — abnormal blood vessel bypassing liver.
• Patellar luxation (Routine) — kneecap slips out of groove.
• Periodontal disease (Routine) — the most-diagnosed condition overall in adult dogs.
• Tracheal collapse (Routine) — floppy trachea in small breeds (Pomeranian, Chihuahua, Yorkshire Terrier).

• Patellar luxation — Patellar palpation by a vet
• Portosystemic shunt — Bile-acid blood test; imaging

Feeding

Small stomachs, fast metabolisms. Feed a diet formulated for small breeds, split across three or four meals a day as a puppy and two as an adult; toy puppies can become dangerously hypoglycaemic if a meal is missed. Portions are tiny, which means treats and table scraps overwhelm the daily allowance startlingly fast — a single biscuit can be a meaningful share of a 4 kg dog's intake. Dental disease is near-universal in small breeds, so ask your vet about diet texture and dental care from the start.

Exercise and enrichment

Stated requirement: Moderate — 30 min/day.

Moderate daily exercise plus mental stimulation. Adaptable to apartment life provided the daily walk actually happens every day.

Coat and grooming

Long, fine, silky, hair-like coat. Brush daily if kept long, or keep it in a short 'puppy clip' — which most owners sensibly do.

Climate and living conditions

Stated suitability: Excellent for apartments; grooming-intensive..

This breed is well adapted to hot climates — which is one of the strongest practical arguments for it. It still needs shade, unlimited fresh water, and walks outside the hottest hours, but it is not fighting its own biology to live here.

Ageing and senior care

Life expectancy: 13–16 years. This dog is a senior from around 9–10 years, at which point wellness examinations should move to twice a year and senior blood and urine screening begins. Small dogs age slowly and often live into their mid-teens. Dental disease and heart-valve disease are the two things that most often shorten a small dog's life, and both are catchable early.
