Bullmastiff Resource


Developed in England as the gamekeeper’s night dog, the Bullmastiff represents a cross between the Mastiff and the Bulldog. The breed’s job was to warn the gamekeeper of poachers and, if necessary, throw and hold the intruder but not harm it. The breed is powerful and compact; males stand up to 27 inches at the shoulder and may weigh up to 130 pounds. The coat is short and dense in red, fawn or brindle, all with a black face mask. The coat sheds little, and a good weekly rubdown keeps it gleaming and free of dead hair. The Bullmastiff makes a loyal family pet and a superb guard dog. These dogs have been known to do well as apartment dwellers but are really house and garden types.
