The Bullmastiff is smaller in size than the English Mastiff, and has a more compact face. These dogs are strong and alert, powerful and active. The foundation breeding was comprised of 60% Mastiff and 40% Bulldog. As a result, these dogs are almost always docile and well-mannered, but also very serious. They are normally fawn, red, or brindle, and they always have a black muzzle. In addition, their ears hang down, and their nose and eyes are always black.

The Bullmastiff was developed in England in the mid to late 1800's as a cross of 60% Mastiff and 40% Bulldog. They were mainly night watchdogs, often called "the gamekeeper's night dog," as they attacked poachers and pinned them to the ground.

Because the Bullmastiff was trained to pin down would-be poachers, aggressive games are not recommended. These dogs do require a lot of exercise, however, so long walks or free-roaming spaces are ideal.

These dogs require little trimming or grooming, and are not very active indoors. They love the open spaces of the country or the suburb. They are tremendously strong dogs, developed originally as protection dogs against poachers. They will, however, integrate well with other dogs. This breed responds well to early, firm obedience training, and are best for active, experienced owners.

The Bullmastiff is a short lived breed, normally ten years or less. These dogs are susceptible to hip dysplasia, bloat, serious tumours, and eyelid abnormalities. Also of concern are osteochondritis dissecas (O.C.D., a joint disorder), hypo-thyroidism, renal failure, and lymphoma sarcoma.

These dogs will seldom back down once aroused, and should be accustomed to strangers at an early age. They can be stubborn and tremendously strong, refusing commands from family members who have not yet established control over them. Caution should be taken if you have other, smaller pets. Exercise, early socialization, and full obedience training are required. In addition, these dogs may drool.

Aggressive games are not recommended with this breed!
