Origins of the breed
Boxers are directly descended from Bullenbeissers, which were bred by huntsmen to help catch game. The dogs’ jaws therefore had to be as wide as possible, with widely spaced teeth for biting firmly and holding on tight.
Bullenbeissers that had these characteristics were used as breeding stock; function and utility were the only breeding criteria at the time. The results of this selection were dogs with broad muzzles and upturned noses – the Boxer as we know the breed today.
