The Bullenbeisser (also known as the German Bulldog) was a breed of dog known for its physical strength and agility. The breed was closely related to the Bärenbeisser (some believe that the two breeds were the same (the names mean "Bull-baiting" and "Bear-baiting"), and the Boxer. It was in all its aspects similar to the present Spanish Bulldog and very alike to the Dogo Argentino, not only in aspect, but also in usage. There were two regional varieties, the Brabanter Bullenbeisser and the Danziger Bullenbeisser. The breed is now extinct.
