Bullmastiff Breed Profile

The Bullmastiff has developed into a useful working dog in a variety of organisations due to the manner in which they will calmly subdue and hold their target rather than attacking viciously.

History of the Bull Mastiff

The first Bull Mastiffs (originally known as the Gamekeeper’s Night Dog) came into being around 1860, a cross between the Mastiff and the Bulldog. They were bred for a very specific purpose: to help gamekeepers in their job of protecting their employers’ game from poachers.

The landowners needed their game kept safe to enable them to feed their families and the estates’ hundreds of workers, but the poachers were also desperate to eat and their aim was to catch the landowners’ deer and other animals. If challenged, they were as likely to shoot the gamekeeper as to risk being caught, as poaching was a capital offence, and so the gamekeepers needed some serious canine back-up.

This required a large, courageous dog, who was quiet enough to sneak up on the poachers without being heard. Once close enough, the job of the Bull Mastiff was not to attack the poacher but instead to grab him and pull him to the ground, and then to sit on him until the gamekeeper arrived to apprehend him!

Owners of Bull Mastiffs today recognise both the almost silent nature of their beloved breed, and their love of sitting on people and trying to pretend they are a lapdog!

Bullmastiff character

Protective and loyal to their family, the Bullmastiff's inherent power makes them somewhat of a handful to manage although they should never exhibit unnecessary aggression. Excellent guard and watchdogs due to their suspicion of strangers and protective nature.

Bullmastiff size

Dogs should measure 64-69cm and bitches 61-66cm, with weights of 50-59kg and 41-50kg respectively.

Bullmastiff health

Another large breed that is prone to Hip Dysplasia and Bloat.

Bullmastiff care

With their size care should be taken to properly socialize them as otherwise they can cause all kinds of chaos!

Remember! All breed profiles are general and every dog is an individual.
