The Bullmastiff is a naturally fearless and protective dog. This breed was developed by crossing the bulldog with a mastiff by British gamekeepers to protect the country estates from poachers.
The British Gamekeeper was looking for a large, strong, fearless, quiet and active dog who could be a silent watchdog and who could track down poachers and hold them until the owners arrived.
They chose the mastiff for their size, but they were not aggressive enough, so they chose bulldogs to mix with the mastiff because bulldogs are brave and have the strength to hold a man down.
This cross breed between Mastiff and Bulldog became very popular and they got the name as Bullmastiff, and they became known as Gamekeeper’s Night Dogs.
Eventually, poaching declined. Since then, these breeds have gotten a new role as guard dogs or watchdogs.
In 1924, Bullmastiff was recognized by the English Kennel Club (EKC) as a purebred dog, and in 1934, the American Kennel Club (AKC) also recognized this breed.
The Bullmastiff is a large and powerful bulldog. They look formidable. They have broad heads with wrinkles; short, squire muzzles; black noses; hanging downward ears; and almond-shaped dark eyes.
