My brother was walking down the street, and this man was walking his Mastiff. A cross the street this other man had two pitbull . His pitbulls ran toward the man and his Mastiff. When they got about afew feet from the Mastiff the mastiff stood his ground and look right at them and they stop and looked at the mastiff and backed off. Is there something about the mastiff that no other dog is a match for him ?
