Are the Bullenbeisser and Mexican Hairless Dog both dogs?
Bullenbeisser The Bullenbeisser (also known as the German Bulldog) was a breed of dog known for its strength and agility. The breed was closely related to the Bärenbeisser (some believe that the two breeds were the same; the names mean "bull-biter" and "bear-biter," respectively), and the Boxer. It was, in all its aspects, similar to the present Alano Español (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.
Buelingo The Buelingo is a modern American composite breed of belted beef cattle. It was created in North Dakota, in the United States, in the 1970s, and is named for one of the breeders, Russ Bueling. The hybridisation started from animals of Angus and Shorthorn type, which were crossed with Limousin and a Dutch Belted bull to fix the gene for belting; this was purely for appearance. Chianina blood was later added to improve the composite breed. In 1989 a breed society, the Buelingo Beef Cattle Society, was started.
