Temperament & character

The Tibetan Mastiff is independent, territorial, and very wary of strangers, while remaining loyal to its own family. It often makes decisions on its own and is not geared toward obeying commands.

Exercise & stimulation

Exercise needs are moderate; the breed is more a deliberate guardian than an endurance athlete. Nocturnal guarding and barking behavior is breed-typical and should be factored into how it's kept.

Grooming

The very dense, long double coat requires regular brushing, especially during its pronounced seasonal shed. Given its size and weight, slow, controlled growth should be ensured during puppyhood.

Suitable for beginners?

Not well suited to the inexperienced, since its pronounced guarding and territorial instincts require experienced, consistent leadership as well as sufficient space. Because of its independence, the breed cannot be trained for quick obedience.

Health & common problems

Hip and elbow dysplasia, autoimmune thyroid disease, and a hereditary form of hypomyelination in puppies have been described as breed-typical. Breeding stock should be X-rayed for hip/elbow dysplasia, and puppies should be monitored for neurological abnormalities.

Good with: Experienced owners with a large, fenced property
