Poachers in 19th century England risked severe penalties; many would kill rather than face arrest. For protection, gamekeepers turned to the Bullmastiff. The "Gamekeeper's Night Dog" was specifically bred to patrol Britain's vast estates and silently track down illegal hunters.
The Mastiff, whose "awful looks the Traveller did Afright, the Vagabond by Day, the Thief by Night," had the size and courage for the job, but lacked speed and agility; the Bulldog of the fighting pit was over-fierce and too light. Crossing the two produced an ideal dog; fearless, big enough to pin a man to ground, yet controlled enough not to maul him. In sporting contests, few men could stay on their feet against the Bullmastiffs battering lunges.
Though its ingredients are centuries old, the breed has gained prominence only since the 1920's. England's Kennel Club gave recognition in the 1920's, the American Kennel Club in the 1930's. Described as 60 percent Mastiff and 40 percent Bulldog, the Bullmastiff is characterized by a broad, square head and deep, wide chest. A black mask and ears accent a short, dense coat of fawn, red or brindle. Alert, confident and powerful, the Bullmastiff has the courage of a steadfast family protector and his willingness to please, intelligence and even temperament make him unfailing in his loyalty as a family companion.
