Origin & History
The Bullmastiff originated in England in the mid-19th century, developed by gamekeepers to protect estates from poachers. The breed was created by crossing 60% Mastiff with 40% Bulldog to create a powerful, yet more agile dog than the pure Mastiff.
These "Gamekeeper's Night Dogs" were bred to track and hold poachers without mauling them. Their size and strength allowed them to knock a man down and pin him without biting. The breed was officially recognized by the English Kennel Club in 1924 and by the AKC in 1933.
Today, Bullmastiffs are valued as loyal family companions and protectors, maintaining their calm demeanor and natural guarding instincts while being gentle with their families.
