A guard dog from the Himalayas, the Tibetan Mastiff is protective of family and property, and generally aloof around strangers. Highly intelligent, this breed also displays a strong will. These dogs are 24 to 29 inches tall at the shoulder and are solidly built and strong, weighing from 70 to 150 pounds. They have a double coat; the exterior coast is long and coarse, while the undercoat is soft. (The undercoat sheds considerably in warm weather and will require regular brushing during this time.)
The Tibetan Mastiff needs outdoor space for exercise and is known to roam if not properly contained. While generally quiet indoors, they tend to bark at night if disturbed by external noises. They are surprisingly agile and light-footed, and will appear quickly if they perceive a threat.
