The Boxer is a medium-sized, short-haired breed of dog, developed in Germany. The coat is smooth and tight-fitting, colors are fawn or brindled, with or without white markings, and white. Boxers have broad, short skulls, have a square muzzle, an underbite, very strong jaws, and a powerful bite ideal for hanging on to large prey.
Boxer was bred in Germany from a now-extinct and larger breed of dog called the Bullenbeisser and the Bärenbeisser, commonly used for hunting. When crossed with the English Bulldog (as a result, they have the characteristic square jaw and squared shoulders), the breed was first brought to show in the 1890s.
These dogs were used by German forces during the world wars as guard dogs and couriers. Besides, their function was to pull carts, to fight and to round up livestock. They later became popular theater and circus dogs.
The breed became internationally popular in the 1950s.
Nowadays Boxers are very useful as police dogs as well as service, guide and therapy functions. Boxers have a wide use in military work too. An excellent watchdog, the Boxer will restrain an intruder. They are extremely athletic. This dog needs to go on a daily pack walk. Daily mental and physical exercise is important. They are easy to train (to socialize). This breed typically lives for 10 to 12 years.
