Boxers are descendants of extinct bullenbaiser breeds crossed with mastiff, bulldog and possibly Great Dane and even a terrier. They were developed in Germany in the 19th century, initially as bull baiting dogs and later as butcher's helpers, controlling cattle in slaughterhouses. Some breed historians say boxers are named from the German word boxl, their slaughterhouse designation. Other fanciers contend the name boxer comes from the characteristic way that they use their forepaws to play, sparring much like a human boxer. Boxers were not imported to the United States until after World War I. After 1940 the breed rose to become among the most popular in America.
