The history of the Boxer dates back to nineteenth-century Germany, where they were used for hunting deer and boar. The ancestors of the Boxer include the Bullenbeiszer and the Barenbeiszer, which are now both extinct. The crossing of those breeds with the English Bulldogs of the 1830?s resulted in the Boxer as we know it today. Boxers were bred to be hunting dogs and they earned their name from the ?boxing? pose they are known to take when standing on their hind legs. Later in the breed?s development, it was made apparent that they were also well-suited for herding and the Boxer was used in more than a few circus acts due to its ability to learn tricks quickly and perform them on command. The popularity of Boxers started to increase rapidly in the 1860?s when the German Boxer Klub was founded. At the turn of the 20th century the Boxer made its way to the United States and the American Kennel Club recognized the Boxer as a breed in 1904.
