The Bullmastiff is a powerful dog, which was originally a cross between the English Mastiff and the Old English Bulldog. Originally bred to find and immobilize poachers, the breed has proven its value as a family pet.
Adult male bullmastiffs should be 25 to 27 inches tall (63.5 to 68.5 cm) at the withers and 110 to 130 pounds (50 to 59 kg). Females typically reach 24 to 26 inches (61 to 66 cm) at the withers, and 100 to 120 pounds (45 to 55 kg). Exceeding these dimensions is discouraged by breeders as they are too big to do their jobs.
Any shade of brindle, fawn, or red is allowed as long as the colour is pure and clear. In the United States, however, there is no mention in the standard of the colour being "pure and clear". The fawn is a light tan or blond colour, while the red is a richer, red-brown. This can range from a deep red to a light red merging with the fawn sometimes described as a red-fawn. A slight white marking on the chest is permissible, but other white markings are undesirable. A black muzzle is essential, toning off towards the eyes, with dark markings around eyes contributing to the expression.
The Bullmastiff is courageous, loyal, calm, and loving with those it knows. It has a very strong protective instinct and will defend its owners against anything it perceives as a threat. However, it does not normally attack to protect. Instead, it knocks the intruder over with its massive size and pins them to the ground, or, will simply stand in front of the stranger/intruder and refuse to let them pass. Bullmastiffs become intensely attached to their families and do best when they can live inside with them. Their protective instinct combined with their great size and natural wariness of strangers means that early socialization is a must. The Bullmastiff may or may not get along well with other dogs. Occasionally, females in heat will also not get along with other females. The Bullmastiff gets along well with children and is very loving towards them. Parental supervision must be maintained when they are with children; they may knock smaller children down accidentally because of their large size.
Bullmastiffs are prone to certain hereditary diseases. These include:
Bred by English gamekeepers
in the 1800s to tackle poachers, the Bullmastiff (also known as a Gamekeeper's Night Dog) was a cross of 40% English Bulldog
for its agility and tenacity (which was the Old English Bulldog
, not the short, fat Bulldog of today) and 60% English Mastiff
for its size, strength and loyalty. They bark much less often than other breeds, but when they bark they will make your head turn, as it is dark and hollow sounding.
The Bullmastiff was recognized as a pure-bred dog in 1924 by the English Kennel Club.
In October, 1933, The American Kennel Club recognized the Bullmastiff. The first standard for the breed was approved in 1935.
The standard has undergone several revisions since then. The most current version is available on the AKC web site.
