Bullmastiff: Dog Breed Info

Bullmastiffs are fearless dogs that were bred to keep the estates and game of English aristocracy from poachers. The typical Bullmastiff is a strong, powerful, swift, and brave dog that will fiercely protect its owner. The first mentions of Bullmastiffs occur in the 1860s in England. The Kennel Club accepted the Bullmastiff breed into its ranks in 1924, while the American Kennel Club did the same nine years later in 1933.
