This almost square breed ought to be active and powerful — a mixture of strength, endurance and endurance. It must seem to be 60 percent mastiff and 40 percent bulldog. Its gait is smooth and strong, but its angulation is mild. Its coat is short and compact, and its own expression keen and attentive. These features allowed the bullmastiff to both overtake and over-power intruders.

The bullmastiff is quiet and gentle, a dedicated companion and protector. It isn’t easily roused, but after threatened it’s fearless. It’s stubborn and can’t readily be goaded into actions contrary to its own will. Some may be aggressive toward strange dogs, but it’s usually good with other family pets and dogs. It’s good with kids, but it might not be lively enough to meet several kids. The bullmastiff desires a firm but loving home. It isn’t for delicate or shy owners.

The bullmastiff is a huge dog and requires daily exercise to remain fit. Its demands are mild, nevertheless, and may be fulfilled with walks on leash and brief romps. It doesn’t do well in warm, humid weather and usually should be considered an indoor dog. It wants a soft mattress and a great deal of space to stretch out. It drools; a few snore. Coat care is minimal.

Even though the mastiff is among Britain’s oldest breeds, its immediate descendant, the bullmastiff, is likely a rather recent development. It’s correct that periodic references to the bullmastiff, or crosses of their mastiff and bulldog, are available as early as 1791; however, no proof exists that these breeds were bred on. The documented history of this bullmastiff begins close to the end of the 19th century, when poaching game by the big holdings had become such an issue that the gamekeepers’ lives were endangered. They had a challenging brave dog which may wait lightly as a poacher approached, assault on control and subdue but maybe not maul the poacher. The mastiff wasn’t fast enough, and the bulldog wasn’t big enough, so that they grabbed the strains in an endeavor to produce their ideal puppy; the aptly termed “gamekeeper’s night dog.” The favorite color was dark brindle, as it faded into the evening. Since the breed’s reputation grew, but several estate owners picked the puppies as property sentries and favored the milder fawns, particularly those who have black masks, a coloration reminiscent of the mastiff ancestry. Breeders started to aim to get a pure-breeding breed instead of relying upon replicating spans between the mastiff and bulldog. They worked to get an perfect creature that seemed to be 60 percent mastiff and 40 percent bulldog. From 1924, the strain was regarded as pure and has been realized by the English Kennel Club. AKC recognition followed in 1933.
