Breed overview

The Tibetan Mastiff is a large Tibetan dog breed. Its double coat is medium to long, subject to climate, and found in a wide variety of colors, including solid black, black and tan, various shades of red (from pale gold to deep red) and bluish-gray (dilute black), and sometimes with white markings around its neck, chest and legs. According to the American Kennel Club, male Tibetan Mastiffs have a weight of 40-70 kg (90-150 lbs) while females are 30-55 kg (70-120 lbs).

Breed facts

  • The term mastiff was assigned by the Europeans who first came to Tibet because that name was used to refer to nearly all large dog breeds in the West.
  • Early Western visitors to Tibet misnamed several of its breeds, such as the Tibetan terrier, which is not a terrier, and the Tibetan spaniel, which is not a spaniel.
  • A better name for the breed might be the Tibetan mountain dog or, to encompass the landrace breed throughout its range, the Himalayan mountain dog.
  • Originally these dogs were used to protect Buddhist monasteries and monks of Tibet from animals such as bears, wolves and snow leopards.
  • The Tibetan Mastiff is a phenotypically distinct dog breed that was bred as a flock guardian in the high altitudes of the Himalayas and the Tibetan Plateaus.

Size and appearance

It typically retains the hardiness which would be required for it to survive in Tibet, Ladakh and other high-altitude Himalayan regions. Instinctive behaviors, including canine pack behavior, contributed to the survival of the breed in harsh environments. It is one of the few primitive dog breeds that retains a single estrus per year instead of two, even at much lower altitudes and in much more temperate climates than its native climate. This characteristic is also found in wild canids such as the wolf and other wild animals. Since its estrus usually takes place during late autumn, most Tibetan Mastiff puppies are born between December and January.

Personality and behavior

As a flock guardian dog in Tibet, and in the West, it uses all the usual livestock guardian tactics (e.g., barking, scent-marking perimeters) to warn away predators and avoid direct confrontations. As a socialized, domestic dog, it is able to comfortably live in a spacious, fenced yard with a canine companion; however, it is not an appropriate dog for apartment living. The Western-bred dogs are generally more easy-going, although still somewhat aloof with strangers. Through hundreds of years of selective breeding, the breed is known for being a nocturnal sentry, keeping potential predators and intruders at bay and barking at unidentified sounds throughout the night. They often sleep during the day, making them more active, alert, and aware at night.
