History & Overview
The Tibetan Mastiff, also known as Do Khyi, is one of the world’s most ancient breeds. It has been used by Tibetans a guard dog for centuries. Its primary role is to guard the home, but some are also used as village guardians and occasionally as protectors of livestock. They act as barking sentinels rather than attack dogs. Today, Tibetan Mastiffs are used as guard dogs and protection dogs. The Tibetan Mastiff was first brought to the United States in the late 1930s, but it was not until the late 1960’s that the dogs began to flourish here.
The Tibetan Mastiff’s personality is described as calm, patient, aloof, and independent, but with its human family, he is also affectionate, playful and gentle. With intruders, he is aggressive and fearless.
This is a powerful, heavy-boned Molossian type dog with a massive head, folded ears and an upcurled, spitz-tail. The thick, insulating coat is unusually dense. Its favored coat color is black-and-tan, but other colors from black to golden also appear. A white “heart-spot” on the chest is traditionally said to signify bravery. A male at maturity is 80 lbs. or more and the height at the shoulders is at least 27½ inches.
