The Tibetan Mastiff (Tibetan: འདོགས་ཁྱི, Wylie: Dogs khyi; Chinese: 藏獒, Pinyin: Zàng áo , Nepali: भोटे कुकुर) is a large Tibetan dog breed belonging to the mastiff family. Originating with the nomadic cultures of Tibet, China, Mongolia, India and Nepal, it is used by local tribes of Tibetans ,Nepalis and Indians to protect sheep from wolves, leopards, bears, large mustelids and tigers. A better name for the breed might be the Tibetan Mountain Dog or, to encompass the landrace breed throughout its range, the Himalayan mountain dog. Photoshop is often used to make dogs of normal color(s) appear white in advertisements. In 2014, a study added the Leonberger to the list of possible relatives.
