Description of a Argentine Dogo.

In the 1920s in Argentina, Antonio Nores Martinez started breeding a dog intended to not only be a pet and family guardian, but also a hunting dog capable of taking on big game such as wild boar and cougars.

Martinez picked the Cordoba Fighting Dog to be the base for the breed. This breed is extinct today but was described as a large and ferocious dog that was both a great hunter and fighter. He crossed it with Great Dane, Boxer, Spanish Mastiff, Old English Bulldog, Bull Terrier, Great Pyrenees, Pointer, Irish Wolfhound and Dogue de Bordeaux. Martinez kept improving the resulting breed via selective breeding to introduce the desired traits. The first standard for the Dogo Argentino was written in 1928.
