The Boxer is a breed of medium to large-sized, short-haired dogs developed in Germany. Their coat is smooth and tight-fitting; colors are fawn, mahogany, sealed brindle (black) 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. The Boxer is classified as a member of the Working Group.

Boxing is a martial art and combat sport in which two people throw punches at each other, usually with gloved hands. Historically, the goals have been to weaken and knock down the opponent.
