The Boxer's body is compact and powerful. The head is in proportion with the body. The muzzle is short and blunt with a distinct stop. The nose is large and black with very open nostrils. The jaw has an under bite. The eyes are dark brown. The ears are set high, either cropped or kept natural. When cropped they are trained to stand up on the head, tapering to a point. When left natural the ears are thin, falling forward, lying close to the head. The neck should be round, strong and muscular, without a dewlap. The muscular front legs are straight and parallel when viewed from the front. The back legs are well muscled. The tail is set high and usually docked. The AKC severely penalizes a natural tail, while most of Europe has outlawed this practice. Dewclaws are usually removed. The short, smooth, close-fitting coat comes in fawn, brindle, tan, mahogany and black often with white markings. Boxers also come in a white coat that cannot be registered with some clubs.
