Originally bred to protect game and discourage poachers on English estates, the Bullmastiff's heritage belies the fact that he is now a family dog. The foundation for this noble breed was 60% Mastiff and 40% Bulldog, according to the American Kennel Club (AKC). Power and agility are inherent along with alertness and a mild suspicion of strangers. A Bullmastiff is not for a timid owner.

The Bullmastiff is unsuitable as an outside dog. The affection of a lap dog is combined with his weight and strength. Any owner must be prepared to provide obedience training mixed with a lot of kindness.

Although the exact dates of this breed's origins are not known, literature mentions a combination of a Bulldog and a Mastiff that was known as the "Strong-Bulldog." Breeders have been exceedingly careful to select particular mental and physical characteristics. Today's Bullmastiff has little in common with his original Bulldog or Mastiff ancestors.
