Tibetan Mastiff

This still-primitive Tibetan Mastiff dog breed was developed centuries ago in Tibet. Originally used as guard dogs for livestock and property, Tibetan Mastiffs can still be found performing that role, but they also enjoy life as family companions and show dogs.

Despite their massive, intimidating size, these pups are big softies when it comes to their human families. They retain their guardian nature, though, so strangers must beware, and introductions from trusted humans go a long way.
