Tibetan Mastiffs have been bred by Tibetan nomads and protecting Buddhist monasteries for thousands of years.
How Many Types of Tibetan Mastiffs Are There? There are two types of Tibetan Mastiff: Do-khyi (“nomad” type) and Tsang-khyi (“monastery” type). The latter is taller and heavier, with more face wrinkles. There is also a rare regional type of Tibetan Mastiff called the Bearded Tibetan Mastiff, which is about half the size of Tibetan Mastiffs and features a beard and wiry coat. It’s a type very rarely seen outside of Tibet, however.
