Bullmastiff
The Bullmastiff is a large, powerful working dog breed celebrated for its protective instincts, muscular build, and gentle loyalty to family.
Origin Story
Originating in England during the mid-to-late 19th century, the Bullmastiff was created by gamekeepers to guard estates against poachers. The breed was established by crossing the English Mastiff for size and strength with the Old English Bulldog for tenacity and agility, typically in a 60:40 ratio. This purposeful blend produced a reliable guardian, officially recognized by The Kennel Club (UK) in 1924 and the American Kennel Club (AKC) in 1934.
Classification

The breed exemplifies the fusion of mastiff and bulldog lineages, aligning with major kennel club standards globally.
