The Bullmastiff is a breed of dog. It started in 19th-century England. It is a mixture of a bulldog and a mastiff. It has a short tan, reddish-brown coat 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.
