Dogo Argentino is the result of a breeding programme started by Dr. Antonio Nores Martinez and his brother Agustin in the 1920's. Inspired by the legends of the mighty Alaunt and the working Viejo Perro de Pelea Cordobs specimens raised by their uncle Oscar, the Martinez brothers decided to create a more versatile and friendly dog, posessing the drive and tenacity of a fighter, but also the size, trainability and hunting qualities of their favourite European breeds. Developed from old white Bullterriers, Cordoba Fighting Dogs, English Pointers, Deutsche Dogges, French Mastiffs, Spanish Mastiffs,, English Bulldogs, Pyrenean Mountain Dogs and even some Irish Wolfhounds and German Boxers, the Dogo Argentino was intended to be the best large game hunter and watchdog in South America. Proven as an excellent puma and jaguar hunting dog, this white mastiff also found a place for itself in the world of dog-fighting, where it gained notoriety as a fearless and tireless pit fighter. Although a lot of its aggressiveness has been bred out of the modern Argentinian Mastiff, it is still sometimes pitted against other dogs and large cats in its homeland and around the world, which is unfortunately creating some bad publicity for this noble breed. Recognized by the FCI in 1973 and believed by many to be the ultimate hog catching dog, the mighty Dogo Argentino is deservedly becoming one of the most popular hunting breeds on the planet.
This is a breed in need of early socialization and reasonably firm handling. The Argentinian Mastiff is protective and territorial, a good choice for a property watchdog and personal guardian, but while this is undoubtedly a tough working breed, it is quite sensitive and gentle, at times even described by some owners as a "needy" dog. Exceptionally devoted to its master, the Dogo Argentino is affectionate towards children, making it an excellent household pet. There are still some health issues, like skin problems due to the extreme lack of pigmentation encountered in certain lines, as well as a high rate of inherited deafness and kidney diseases, but these traits are on their way of being eliminated through careful breeding. The ears are usually cropped, although unaltered dogs can be seen too.
The coat is short, flat and smooth. The colour is always solid white, but very small dark markings on the head are acceptable. Average height is around 26 inches.
