Bullmastiff’s nickname is “”The Gamekeeper’s Night Dog””, and it pretty much explains the early history of the breed.

During the middle of the 19th century, the vast country estates and game protection of the English elite were tireless targets of hunters. “”The punishments were severe,”” one breed historian wrote, “”yet poaching was impossible to eradicate only by laws.”” Because a hunter could face the death penalty if captured, they had nothing to lose during the encounter with the gamekeeper of the property. They can choose to shoot it with the game player when he corners instead of hanging.

The gamekeepers responded to the dogs in a big, fast, and brave manner and did enough to lead and pin a man who was advancing the field in the dead of night. Eventually they hit the right combination of breeding stock by surpassing the Mastiff in the ratio of 60 percent Mastiff and 40 percent Bulldog on Bulldog. The new breed was smart enough to operate on command, enough traffic to hold but not a hunter to Maul, big enough to scare the Bejes off any intruder.

Inevitably, a rivalry developed between the UK gamekeepers, who had the best quality bullmastiffs. The best specimen competitions and exhibitions were staged, and from there the show was a short jump to the Bullmastiff in the ring. Dog shows in England were gaining in popularity just as Bullmastiff fans were standardizing their breed. By 1924, the Bullmastiff as we now know it was ready to join the ranks of the Kennel Club (England). The AKC gave full recognition to the breed in 1933.
