Rugged, muscular and larger than most Tibetan dogs, the Amdo Mastiff belongs to a typical "bear" type of mountain dogs. In comparison to the western-bred Do-Khyi, the Amdo has a shorter snout and a wider head, as well as a more squarely built body frame. Its rich dense undercoat makes this longhaired Moloss perfectly suited for harsh climates of Tibet, but can be a problem during the summer months in warmer countries.
Most dogs are black, brown or grey, always with tan and white markings. The average height is around 30 inches.
