Boxer

Developed in Germany, the Boxer is a breed of stocky, medium-sized, short-haired dog. The coat is  smooth and  fawn or brindled, with or without white markings. Boxers are brachycephalic (they  have  broad, short skulls),  and have a square muzzle, mandibular prognathism (an underbite), very  strong jaws and a powerful bite ideal  for  hanging on to large prey.

The Boxer was bred from  the Old English Bulldog and the now extinct Bullenbeisser and is part of the Molosser group. Boxers were first exhibited in a dog show for St. Bernards in Munich in 1895, the first Boxer  club  being founded the next year. Based on 2011 American Kennel Club statistics, Boxers are the seventh most popular breed of dog in the United States for the second year in a row, moving down from sixth where they were ranked for the previous three years
