The Bullmastiff breed is a compact, powerful, muscular dog with a large, square head. The coat is short, hard and weather proof and comes in fawn, red or brindle, with a black muzzle. Adult dogs measure 64-69cm and weigh 50-59kg; adult females measure 61-66cm and weigh 41-50kg.
These dogs are very protective of their family and other household pets, and so have to be socialised from an early age. The Bullmastiff will only accept strangers if they are introduced to them by someone they trust. Other visitors/strangers will be quickly halted in their tracks. It is not really a breed for the novice owner, due to its strength, stubbornness and over-protective nature.
The Bullmastiff dog breed was originally called the 'Gamekeeper's Night Dog' as they were used to catch poachers. The base stock of the Bullmastiff was 60% English Mastiff and 40% Bulldog. They were created in the late 1800s. When the need for gamekeepers and the Bullmastiff declined they were used in sport. Someone would run off into the undergrowth and, after a short time, a muzzled Bullmastiff would be released to see if the person could be found. They were not trained to maul or kill, but to overpower their target.
