History & Origins

The history of Bullmastiff dogs goes back to the 19th century. They were bred by gamekeepers in Britain to fend off poachers. They were bred because of their strength, speed and size. The breeders decided to use a mixture of Bulldogs, which were aggressive and really heavy, with Mastiff dogs, which were equally strong but less aggressive. The result was a dog which they called “The Gamekeeper’s Night Dog” which is close to the breed that we have today. Gamekeepers also preferred brindle ones as it acted as a sort of a camouflage for dogs that protected property at night.

The English Kennel Club accepted the breed as a pure breed in 1924 and established its genetically background as 60% Mastiff and 40% Bulldog. In 1934 AKC officially recognized the Bullmastiff breed and the first standards were approved only a year later.
