At a glance
The Tibetan Mastiff is the ancient guardian dog of the Himalayas — a massive, densely coated giant that is mellow and calm at home, devoted to its family, and aloof, watchful and territorial with strangers. It thinks for itself, will follow instinct over training, cannot be trusted off lead and is known as a night-time barker, so both the AKC and CKC say it is not a dog for everyone and needs securely fenced space rather than a flat.

Health
This page is general information compiled from published sources. It is not veterinary, legal or purchase advice. Dogs vary within a breed — talk to a vet or a reputable breeder about the dog in front of you.
Health notes are not veterinary advice. Conditions listed are those reported for the breed, not a diagnosis of any dog. Always consult a veterinarian.
Hip dysplasia
Commonly reported in the breed; breeders screen hips by X-ray. Ask your vet about hip screening and about keeping your dog lean and fit.
Elbow dysplasia
Commonly reported in the breed; breeders screen elbows by X-ray. Ask your vet if you notice front-leg lameness, especially in a growing dog.
Hypothyroidism
Hypothyroidism is reported in the breed. Ask your vet about thyroid testing if you notice weight gain, lethargy or coat changes.
Epilepsy
Idiopathic epilepsy is reported in the breed. Ask your vet promptly if your dog has a seizure.
Cherry eye / eyelid problems
Eyelid and tear-film problems (cherry eye, entropion, dry eye) are reported in the breed. Ask your vet if the eyes look red, sore or weepy.
Behaviour
Guardian first — not for everyone
The CKC warns this is not the dog for everyone and can challenge even experienced owners: patient, gentle and loyal, but independent, powerful, suspicious of strangers and ready to defend fiercely; it can turn destructive when bored and is inclined to bark at night, so fenced property is an absolute must. The AKC likewise describes a mellow house dog that is aloof and territorial with strangers.
Follows instinct over training; never off lead
The AKC says the breed does not respond well to conventional obedience: it learns fast, sees no point in repeating what it knows, is not food-driven, may perform in class and ignore commands at home, and has no reliable recall — it should never be trusted off leash. It prefers patrolling its territory to structured play and is more active in cool weather.
Energy and exercise
Energy level is rated 3/5 (moderate) on the AKC breed-trait chart. The Royal Kennel Club puts its exercise need at "up to 1 hour per day".
Training and barking
AKC trait chart: trainability 3/5, barking level 3/5. Individual dogs vary; early socialisation and reward-based training are recommended for every breed.
