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 owner's job is to give it somewhere to go.
Temperament and training
Stated temperament: Playful, mischievous and courageous; a robust, clownish bully with strong 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.
Conditions this breed is predisposed to
Chronic kidney disease (CKD)
Congenital deafness
Patellar luxation
Health screening — what to test, and when
| Screen for | Test | When |
|---|---|---|
| Chronic kidney disease (CKD) | Blood (creatinine, SDMA) with urine concentration | Annually from 7 years; sooner in predisposed breeds |
| Congenital deafness | BAER hearing test | As a puppy, in white, merle, or blue-eyed lines |
| Patellar luxation | Patellar palpation by a vet | At each annual examination from 12 months |
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
- Chronic kidney disease (CKD) — Blood (creatinine, SDMA) with urine concentration
- Congenital deafness — BAER hearing test
- Patellar luxation — Patellar palpation by a vet
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 - 45-60 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: Good for warm climates - the short flat coat tolerates heat, but white dogs need sun protection.
Ageing and senior care
Life expectancy: 11-14 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. Senior care →
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.
