An excellent guard dog, similar in appearance to the Dogue de Bordeaux, but resulting from a cross between the Mastiff and the English bulldog.

The Bullmastiff was created in England in the late 1800s by gamekeepers who wanted to protect their estates from poachers.

The gamekeepers' dogs had to be very couragious and tenacious to be able to catch and hold the poachers who used every means and devices to escape, since punishment for poaching was hanging.

These dogs were known as Gamekeeper's Night Dogs and are the ancestors of today's Bullmastiffs.

The breed takes its name from its two parent breeds, the Bulldog and the Mastiff. Bullmastiff breeders in the US, favored a slightly higher percentage of Mastiff blood (60% Mastiff, 40% Bulldog), while the British fanciers kept close to a half-Mastiff, half-bulldog combination.

It was created to be faster and more aggressive than a Mastiff, while less savage than a bulldog (of those days). The outcome had to be as loyal of the Old English Mastiff, which was reputed to have roamed only his master's property, never trespasing its bounderies.

The breed received official recognition by the Kennel Club in 1924 and by the AKC in 1933. From then on a distinction is made between cross-bred bullmastiffs and pure-bred bullmastifs (those with at least three generations of Bullmastiffs).
The breed was further standardized by S.E. Moseley who is considered the father of the modern Bullmastiff. One of his Bullmastiff bitches, Farcroft Silvo, became the first champion of the breed.
The Bullmastiff looks like a Mastiff with a Bulldog's head and is interdmediate in size bewteen the two breeds. It has a strong, muscular body structure, without being too heavy.

The skull reminds the bulldog ancestry. It is very broad and square and its circumference can equal the dog's height at the withers. The stop is very marked and the muzzle is shorter than that of a Mastiff.
Originally dark brindles were favored as dark colors were preferred for night work as a guard dog. These dark colors progressively gave way to fawns. Today any shade of brindle, fawn or red is accepted, with or without a slight white marking, but only on the chest. The muzzle is black.

Despite his ferocious outlook, today's bullmastiff is surprisingly quiet and docile/ However, it has lost none of its power and determination when it has to defend his family or home. Otherwise, the Bullmastiff is very playful and always eager to learn something new.

Bullmastiffs are usually very dependable with children, but should nevertheless always be kept under supervision by an experienced dog person due to their powerful structure.

An excellent dog for those who want a molosser breed but do not have the space to keep a giant breed. Bullmastiffs bark less and will not need as much exercise as some other, more excitable, guard dog breeds.
