The Boxer is a breed of stocky, medium-sized, short-haired dogs developed in Germany. Their coat is smooth and tight-fitting; colors are fawn or brindled, with or without white markings, which may cover the entire body, and white. Boxers are brachycephalic (they have broad, short skulls), have a square muzzle, mandibular prognathism (an underbite), very strong jaws, and a powerful bite ideal for hanging on to large prey. The Boxer was bred from the Old English Bulldog and the now extinct Bullenbeisser, and is part of the Molosser group.
Boxers were first exhibited in a dog show for St. Bernards in Munich in 1895, the first Boxer club being founded the next year. Based on 2012 American Kennel Club statistics, Boxers held steady as the seventh most popular breed of dog in the United States for the third consecutive year.
