The bullmastiff is a breed of dog that originated in 19th-century England. It is a mixture of a bulldog and a mastiff. It has short tan, reddish brown hair with black on the face and ears. It stands 24–27 inches (61–69 cm) and weighs 100–130 pounds (45–59 kg). Bullmastiffs were originally used to discourage poaching and are now also used by police and as guard dogs.
