This dog makes a great watchdog, and is gentle and quiet in the home. It needs firm, strong leadership and may be nervous toward other dogs so it should be socialized from a young age.

Breed Overview

Poaching game became such a problem in England in the late 19th century that gamekeepers' lives were in danger. Mastiff-Bulldog cross was bred to create the Bullmastiff which was kept by gamekeepers to ward off game poachers. Bullmastiffs were able to attack on command but not maul the poacher. Bullmastiffs are bold and powerful, yet gentle and quiet. They are protective and fearless. Bullmastiffs are loving companions that are best suited with singles and active people, and they do not do well in hot weather. They require minimal exercise such as a moderate daily walk or play. Bullmastiffs tend to drool and some snore. Their coat requires minimal care.
