The head resembles that of the bull-dog, but with the ears dependent. The upper lip falls over the lower jaw. The end of the tail is turned up, and the fifth toe of the hind foot is frequently developed. The nostrils are separated by a deep furrow. The bark is deep-toned, and the aspect of the animal grave and noble. It is taller than the bull-dog, but the chest is not deep, and the head is large in proportion to the general form. The mastiff is faithful and affectionate, and makes an excellent watch-dog. "The next is the mast if or ban dog, a species of great size and strength, and a very loud barker. Manwood ( Forest Law ) says, it derives its name from Mase the there, being supposed to frighten away robbers by its tremendous voice." -Pennant: Brit. Zool.; The Mastiff.
