Dog And Dog Blog: Bullmastiff Dog

The Bullmastiff is a breed of large dog. A member of the Working Group, it is large and solidly built, with a short muzzle. The Bullmastiff shares the characteristics of Molosser dogs like it, and was originally developed by 19th-century gamekeepers to guard estates and immobilize poachers. The breed's bloodlines are drawn from the English Mastiff and Old English Bulldog; it was recognized as a purebred dog by the English Kennel Club in 1924. It is an athletic and muscular dog, yet docile and obedient, traits which have made the breed popular as a family pet.

Males should be 25 to 27 inches (63 to 69 cm) tall (AKC Std.) at the withers and 110 to 130 pounds (50 to 59 kg). Females should be 24 to 26 inches (61 to 66 cm) at the withers, and 100 to 120 pounds (45 to 54 kg). Exceeding these dimensions is discouraged by breeders, as a larger dog may be too cumbersome and not agile enough to properly perform the job for which the breed was created.

Bullmastiffs are described as fawn, red, or brindle. These are the only acceptable colors in the AKC standard. The fawn can range from a very light brown to a reddish brown. Red can range from a light red-fawn to a dark rich red. Brindles are a striped overlay of the fawn or red. A Bullmastiff should have no white markings, except for on the chest where a little white is allowed. See breed standard under external links for additional details.
