    History & Overview

    Sometimes referred to as English Bullmastiff, the Bullmastiff is a large working dog that originated in Britain in the mid 1800’s as an estate guardian to ward off poachers. The breed was created by gamekeepers and was originally known as the Gamekeeper’s Night Dog.

    The tough, heavy and aggressive Bulldog of the 19th century was crossed with the large, strong, less aggressive Mastiff. The Bullmastiff breed was deemed pure by the Kennel Club in 1924, with a genetic background of approximately 60% Mastiff and 40% Bulldog, hence his name.

    Character

    Bullmastiffs are an excellent choice for a guard dog; however, a stubborn streak makes the animal resistant to obedience training and overly protective of his human family. He is not easily alarmed, but if he feels threatened, the Bullmastiff is fearless. Keep a towel handy because the Bullmastiff is quite a drooler.

    Health & Behavioral Issues:

    Overall, recent study shows evidence of ancestral inbreeding in Bullmastiffs, and unequal founder contributions during breed establishment.
