For centuries, nomadic herders on the Tibetan Plateau and in the Himalayas relied on large, heavily coated dogs to guard their flocks, tents and villages, often tying them by day and letting them patrol at night. The Tibetan Mastiff descends from those guardians, and genetic research shows it carries a high-altitude adaptation inherited from an ancient wolf-like canid. The AKC added the breed to its Working Group in 2006.
These are massive, dignified dogs with a lion-like mane, a plumed tail curled over the back and a coat that thickens in cold climates. Many are calm and gentle with their family yet aloof and territorial with strangers. They think independently, mature slowly, bark at night and need an experienced, patient owner rather than a first-time one.
