bullmastifThe Bullmastiff is a powerful dog breed that is said to be across between the English Mastiff and the English Bulldog. It may look massive and imposing, but Bullmastiffs are quite affectionate and friendly for a working breed. Although not as popular today, there are several owners that are still loyal in trying to preserve the breed.

Breed Origins

initially bred by English gamekeepers during the 1800’s to guard their large estates and to tackle poachers, the Bullmastiff was a cross of the English Bulldog for its agility and tenacity and the English Mastiff for its size, strength and loyalty. This breed usually bark less often than other breeds. But when they do bark they make dark and hollow sounding barks that can immediately take some notice.

Appearance and Size

Bullmastiffs have a powerful and muscular build with a large and broad wrinkled head. They have a compact body yet powerful and imposing. They have a short, dense and smooth coat. A typical Bullmastiff stands around 25 to 27 inches tall at the shoulders and weigh from around 110 to 150 pounds. Females are slightly smaller in size.


Despite the breed’s stature and strong mean look, Bullmastiffs are actually gentle and affectionate creatures. It is quite docile that it rarely attacks even intruders. But it also has a very strong protective instinct and will always try to defend its owners against perceived threats. But Bullmastiffs do not attack or bite intruders, it merely knocks the intruder over using its massive size and pins them to the ground to immobilize them.

Family and Home Relations

Bullmastiffs become intensely attached and very loyal to their families. They do their best to please so they can live inside with them and be treated as one of the family. The protective instinct of Bullmastiffs and their natural wariness of strangers may require them to undergo early socialization. Depending on their socialization training, Bullmastiffs may or may not get along well with other dogs. As quite the loving and affectionate breed, the Bullmastiff gets along well with children and is very loving towards them. Parental supervision might still be required due to the dog’s massive size.
