The history of the Dogo Argentino and the two brothers who created the breed is as colorful and passionate as the history of Argentina itself. Antonio Nores Martinez was not quite 18 years old and Agustin a year younger in 1925 when Antonio first conceived and took the first step in his vision of a big game hound created specifically for the varied and rugged Argentine countryside.

"I still remember as if it were yesterday... the day when my brother Antonio told me for the first time his idea of creating a new breed of dog for big game, for which he was going to take advantage of the extraordinary braveness of the Fighting Dog of Cordoba. Mixing them with other breeds which would give them height, a good sense of smell, speed, hunting instinct and, more than anything else deprive them of that fighting eagerness against other dogs, which made them useless for pack hunting. A mix that would turn them into sociable dogs, capable of living in freedom, in families and on estates, keeping the great courage of the primitive breed, but applied to a useful and noble end; sport hunting and vermin control."

Agustin Nores Martinez, History Of The Dogo Argentino

It is important to point out that the Fighting Dog of Cordoba, a breed established in that area consisting of Mastiff, English Bulldog, Bull Terrier, and Boxer is now extinct. Much of the early work on the new breed was devoted to eliminating the fighting eagerness and developing the hunting instinct. An effort that was essential and highly successful.
