Bullmastiff

        The Bullmastiff originated from no specific place, but evolved from crossing a Bulldog with an Old English Mastiff.  The result was this wonderful guard dog.  He also needs a lot of exercise, and has a very powerful jaw.  The male is 25-27 inches tall, and the female is 24-26 inches tall.  They are very heavy, with the male weighing 110-130 pounds, and the female weighing 90-110 pounds.  The coat is short, and can be colored brindle, fawn or red.  They are very powerful dogs, and tend to be loyal but stubborn.
