The Bullmastiff is a large-sized breed of domestic dog, with a solid build and a short muzzle. The Bullmastiff is mastiff type dog, and was originally developed by 19th-century gamekeepers to guard estates. The breed was created by crossing the English Mastiff with the  now extinct Old English Bulldog. It was recognized as a purebred dog by the English Kennel Club in 1924. == Famous Bullmastiffs == Bullmastiffs are strong, powerful, but sensitive dogs. For a Bullmastiff to become a well-behaved family member, consistency is needed. Training and socialization is of high importance, as the breed can be independent. Dogs of this breed are natural guardians of their home and owners. No special guard training is needed for a Bullmastiff to react appropriately if its family is endangered. Activities Bullmastiffs enjoy include obedience, agility, tracking, and carting. Butkus – actual pet of actor Sylvester Stallone and featured in the movie Rocky.
