The coat is smooth and tight-fitting; colors are fawn, brindled, or white, with or without white markings. Based on 2013 American Kennel Club statistics, Boxers held steady as the seventh-most popular breed of dog in the United States for the fourth consecutive year. However, according to the AKC's website, the boxer is now the eleventh-most popular dog breed in the United States. Boxers were originally a docked and cropped breed, and this is still done in some countries. A line of naturally short-tailed (bobtail) Boxers was developed in the United Kingdom in anticipation of a tail docking ban there; after several generations of controlled breeding, these dogs were accepted in the Kennel Club (UK) registry in 1998, and today representatives of the bobtail line can be found in many countries around the world. 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.
