History of Bullmastiff

The documented history of the Bullmastiff begins in the 19th century in England. Gamekeepers on large estates needed a canine assistant to deter and apprehend rampant poachers. They crossbred the English Mastiff (approx. 60%) and the Old English Bulldog (approx. 40%) to create a dog with size, strength, agility, tenacity, and courage. The goal was a dog that could track silently, cover ground quickly, and pin poachers without mauling them.

The English Kennel Club recognized the breed in 1924, followed by the American Kennel Club (AKC) in 1933/1934, the United Kennel Club (UKC) in 1948, and the FΓ©dΓ©ration Cynologique Internationale (FCI) in 1955.

Purpose and Popularity of Bullmastiff

The Bullmastiff's original purpose was as the 'Gamekeeper's Night Dog,' silently guarding estates against poachers. They were also used to guard diamond mines in South Africa. While retaining protective instincts, they are now popular, loyal, and affectionate family companions.

In the US, the Bullmastiff's AKC popularity ranking has fluctuated slightly: 67th (2024), 60th (2023), 61st (2022), 56th (2021), and 55th (2020), indicating consistent interest.

Did you know?

The Bullmastiff earned the nickname 'Gamekeeper's Night Dog' because it was specifically bred to silently track and apprehend poachers on English estates under the cover of darkness.
