These 10 breeds, with the Cordoba Dogs as a base, were all added because of their wanted traits. The Cordoba dog had the strength, courage and tenacity wanted. The Great Dane was added to increase the height. The British Bulldog and Bull Terrier for their courage and endurance. The Pointer because of his scenting ability. The Dogue De Bordeaux was added to improve the strength of the jaw. The Great Pyrenees for his white coat and climate adaptabilities. The Wolfhound added swiftness. The Boxer was chosen for his personality and intelligence. And the Spanish Mastiffs, especially the Pyrenean Mastiff, was added due to its white colour, good nose and to increase the size of the dog.

In 1947, after 20 years of a rigorous breeding and selection program, El Dogo Argentino was introduced to the world in the Argentine magazine Diana. Authored by Dr. Martinez, the article presented the first standard for the Dogo. After his tragic death in 1956, the breeding program was left to his brother, Dr. Augustin Nores Martinez, who had assisted Antonio from the beginning of his endeavor in the provence of Cordoba. Today, the Dogo is seen worldwide as one of the greatest large game hunters, as well as impressing many with it's accomplishments in Schutzhund, French ring sport and much more. A loyal companion, a guardian of master and home, and the ultimate hunter, yet the Dogo is a gentle and noble friend to all. The Dogo is not, as many believe, over-aggressive and fierce, but will defend with no hesitation if anything were to threaten their family or home.
