0 Tibetan Mastiffs
The Tibetan Mastiff is an ancient breed and type of domestic dog (Canis lupus familiaris) originating with nomadic cultures of Central Asia. The Tibetan Mastiff also known as Go-khyi (variously translated as "home guard", "door guard", "dog which may be tied", "dog which may be kept"), reflects its use as a guardian of herds, flocks, tents, villages, monasteries, and palaces, much as the old English ban-dog (also meaning tied dog) was a dog tied outside the home as a guardian. However, in nomad camps and in villages, the Go-khyi is traditionally allowed to run loose at night. Males can reach heights up to 31 inches (80 cm) at the withers, although the standard for the breed is typically in the 25- to 28-inch (61- to 72-cm) range. The heaviest dog on record may be one weighing over 130 kg (286.6 lb), but dogs bred in the West are more typically between 140 lb (64 kg) and 180 lb (82 kg)—especially if they are in good condition and not overweight.
