The Bullmastiff is a large-sized breed of domestic dog, with a solid build and a short muzzle. The Bullmastiff shares the characteristics of Molosser dogs, and was originally developed by 19th-century gamekeepers to guard estates. The breed’s bloodlines are drawn from the English Mastiff and the extinct Old English Bulldog. The Bullmastiff was recognized as a pure-bred dog in 1924 by the English Kennel Club. The first standard for the breed was approved in 1935.
Reserved and faithful. 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. No special guard training is needed for a Bullmastiff to react appropriately if his family is endangered.
From 63.5 to 69 cm (M) and 61 to 66 cm (F) / from 51 to 59 kg (M) and 41 to 50 kg (F).
Short, shiny, smooth, close-lying.
Fawn, red, or brindle. A bullmastiff should have no white markings, except for on the chest where a little white is allowed.
