Origin & Background
The Bullmastiff’s origin can be traced back to 19th-century England where they were said to be used mainly to discourage poaching on reserves and estates. The Bullmastiff was also known as the “gamekeeper’s night-dog.” Because the precise “gene pool mixture” can’t be accorded for 100%, the recognized and accepted origin of the Bullmastiff is a cross between the Bulldog and the Old English Mastiff. The English Kennel Club recognized the Bullmastiff as a purebred dog in 1924 and in 1933 The American Kennel Club granted the breed full recognition. It is said that in 1928, the diamond company De Beers, imported Bullmastiff’s to be used as guard dogs at their mines.

A Bullmastiff is an affectionate, alert and loyal companion. They are good family dogs but because of their size, there must always be supervision as the can unintentionally knock a child over. Bullmastiffs tend to be a bit suspicious of people outside of their family, so although they are easy going with family members, their attitude is likely to change should a stranger enter. As with all large breeds, socialization and training are crucial.
