10 extinct breeds of dogs (With Pictures)

8. Cordoba Fighting Dog

Named after its place of origin, i.e. Cordoba in Argentina, this species was born by crossing the bull terrier with Mastiff, English Bulldog and Boxer. Their large bodies were generally solid white, with some brindle and fawn members, too. They were aggressive hunters, so much so that the males and females turned on each other instead of mating. Besides, many died in dog fighting pits. Eventually, they became extinct in the mid-20th century. Dogo Argentino is directly derived from them.
