Size and Build
Tibetan Mastiffs are large, muscular dogs known for their strength and agility. Males usually stand 22 to 24 inches tall, weighing between 64 and 75 pounds, while females measure 20 to 22 inches tall and weigh 55 to 64 pounds. Their sturdy, heavy-boned bodies feature broad chests, deep rib cages, and strong, well-muscled limbs. Despite their bulk, they move with impressive speed and agility when necessary.
Coat and Colors
The breed's dense double coat consists of a heavy, woolly undercoat and a straighter, softer outer coat. A thick mane frames their neck and shoulders, enhancing their lion-like appearance. The tail is heavily feathered, curling over the back, typically to one side. Recognized colors by the Kennel Club include black, black and tan, gold, gray, gray and gold, and gray and tan, often featuring rich markings above the eyes, on muzzles, chests, legs, and under the tail. Some dogs have white chest stars or white on some feet.
Distinctive Features
Their broad, heavy heads boast a pronounced occiput and stop, with blunt wide muzzles and broad, black noses with open nostrils. Eyes are medium-sized, dark brown, oval-shaped, slanting slightly, and set wide apart with dark tight rims. Ears are triangular, pendant, heavily furred, and hang close to the head. Their gait is purposeful and free, supported by straight, muscular limbs and strong, compact feet with thick pads and feathered toes.
Gender Differences
Males generally have a larger size and a more prominent mane compared to females. Temperamentally, both share a calm, protective nature, though males may show more dominant behaviors if not adequately socialized and trained.
