Mastiff Large Dogs

Mastiff: The Mastiff is one of the most ancient breeds, having descended from the Molosser in Asia over 5,000 years ago. This giant breed stands a minimum of 30 inches tall at the shoulder and weighs anywhere from 130 to 220 lbs. The Mastiff has a grand carriage but a gentle and dignified temperament. These dogs are protective of their families and they are much more sensitive than they look. (Photo credit: prometeus/
