Bullmastiff is a dog bred by crossing the bulldog and the mastiff. It was developed in the 1800’s on the great estates of England, which wanted a dog smaller and more agile than the mastiff that would remain quiet until the gamekeeper needed it. The result was a fearless dog that made an excellent guard against poachers. Bullmastiffs stand about 24 to 27 inches (61 to 69 centimeters) high, and weigh 100 to 130 pounds (45 to 59 kilograms). The dog’s short, dense coat may be colored fawn or brindle.
