The territorial, independent, and strong-willed Tibetan Mastiff has been traditionally used as a protector and a solitary sentry. Although patient and gentle with familiar people, it may become aggressive and attempt to guard the home from strangers. To make it less suspicious and anxious, socialize the dog early on.

The Tibetan Mastiff is a relatively healthy breed, and responsible breeders will screen their stock for health conditions such as elbow and hip dysplasia, hypothyroidism, and eye anomalies including entropion and ectropion.
