The Boxer is a medium to large, short-haired breed of dog, developed in Germany. The Boxer is a member of the Working Group. The head is the most distinctive feature of the Boxer. The breed standard dictates that it must be in perfect proportion to the body and above all it must never be too light. However, in 2008 the FCI added a 'naturally stumpy tail' as a disqualifying fault in their breed standard, meaning those Boxers born with a bobtail can no longer be shown in FCI member countries. In the United States and Canada as of 2012, cropped ears are still more common in show dogs, even though the practice of cosmetic cropping is currently opposed by the American Veterinary Medical Association. In March 2005 the AKC breed standard was changed to include a description of the uncropped ear, but to severely penalize an undocked tail.
