Bullmastiffs are a very large working breed that originated in Britain in the mid 1800s as estate guardians to ward off poachers. They were bred by gamekeepers for power & strength, size and speed using a cross of the tough, heavy and aggressive Bulldog of the 19th century with the large, strong, less aggressive Mastiff.As a result, the Bullmastiff is known as the Gamekeeper's Dog. The preferred color, by gamekeepers, was brindle, as this color works as a more effective camouflage, especially at night.
The Bullmastiff breed was deemed pure by the English Kennel Club in 1924, with a genetic background of 60% Mastiff and 40% Bulldog
Bullmastiffs are very strong, powerful, but still sensitive dogs. For a Bullmastiff to become a well-behaved family member, consistency is needed. Training and socialization is of much importance, as the breed can be independent.Dogs of this breed are natural guard dogs of their home and owners. No special guard training is required for a Bullmastiff to react appropriately if its family is endangered. During training, a Bullmastiff requires a special approach, because these dogs do not like to repeat the same actions again and again.
