Old English Bulldog
In 1928, Antonio Nores Martinez, a medical doctor, professor and surgeon, set out to breed a big game hunting dog that was also capable of being a loyal pet and guard dog. Antonio Martinez picked the Cordoba Fighting Dog to be the base for the breed. This breed is extinct today, but it was said that, as a large and ferocious dog, it was a great hunter. Martinez crossed it with the Great Dane, Boxer, Spanish Mastiff, Old English Bulldog, Bull Terrier, Pyrenean Mastiff, English Pointer, Irish Wolfhound and Dogue de Bordeaux. Nores Martinez continued to develop the breed via selective breeding to introduce the desired traits.
