Originating with the nomadic cultures of Tibet, China, India, Mongolia, and Nepal, the Tibetan Mastiff is used by local tribes of Tibetans to protect sheep from wolves, leopards, bears, large mustelids, and tigers. Fully grown mastiffs can weigh up to 286 pounds. One of these pups once sold for $1.5 million!
