Origin and purpose
Working (AKC). Origin: Tibetan Plateau.
Frequently bought and then abandoned due to unmet climate needs.
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: Independent, protective, wary of strangers; not a modern trainable breed
A guarding breed: it is naturally suspicious of strangers, and that is what it was bred for. Early, broad, positive socialisation — many people, many places, many situations, before sixteen weeks — is not optional for this breed; it is the difference between a discriminating guardian and a dangerous liability. A guarding dog that has not been socialised is a problem you have created, not a temperament you have discovered.
Conditions this breed is predisposed to
Elbow dysplasia
Entropion
Hypothyroidism
Health screening — what to test, and when
| Screen for | Test | When |
|---|---|---|
| Elbow dysplasia | Radiographic elbow evaluation | Once at 12–24 months |
| Entropion | Eye examination | Annually |
| Hypothyroidism | Thyroid blood panel | On unexplained weight gain, coat loss, or lethargy; annually in predisposed breeds |
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
- Elbow dysplasia — Radiographic elbow evaluation
- Entropion — Eye examination
- Hypothyroidism — Thyroid blood panel
Feeding
Slow, controlled growth is essential — giant-breed puppies grow for eighteen months or more, and pushing that growth with over-feeding or calcium supplementation causes lasting orthopaedic damage. Use a diet formulated for large- or giant-breed growth and keep the puppy visibly lean. As an adult, two measured meals a day, never one large one. Feeding costs are substantial and should be budgeted before acquiring the dog.
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.
Coat and grooming
Enormous, thick double coat with a heavy mane. Brush 3–4× weekly; daily during the annual moult, which is dramatic. A high-altitude coat.
Climate and living conditions
Stated suitability: Very poor for hot lowlands; suited only to cold, high-altitude climates.
Ageing and senior care
Life expectancy: 10–14 years. This dog is a senior from around 5–6 years, at which point wellness examinations should move to twice a year and senior blood and urine screening begins. Giant breeds age fast and live short lives, and this is the hardest fact about owning one. Senior screening should start early, orthopaedic support matters from middle age, and cardiac and bone cancer risks are real. Go in with your eyes open. 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.
