There are two types of Tibetan Mastiff. The Tsang-khyi is tall with heavy bones and many wrinkles around the face. The Do-khyi is a leaner dog with less wrinkles. Both types of Tibetan Mastiff can be born into the same litter.
The Tibetan Mastiff is a gentle, courageous dog with a strong sense of family loyalty. It acts as a protector and is often kept for guarding homes or flocks against outside predators. The Tibetan Mastiff is a family-friendly pet, but it must be raised and trained carefully from the time it is a puppy. It is wonderful with children and has an even temperament; however, this breed can be wary of strangers and becomes defensive easily.
Because it is a large dog, this breed may not be appropriate for apartment living. It is easily domesticated and does well in homes with small yards. Tibetan Mastiffs need regular exercise in order to remain healthy.Learn more about Dogs
