The Boxer is a medium to large, short-haired breed of dog, developed in Germany. The coat is smooth and tight-fitting; colors are fawn, brindled, or white, with or without white markings. 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. Boxers are generally patient with smaller dogs and puppies, but difficulties with larger adult dogs, especially those of the same sex, may occur. Boxers are generally more comfortable with companionship, in either human or canine form. Boxers are very patient and are great to adopt as family dogs because they are good with children and people of all kinds. The head is the most distinctive feature of the Boxer.
