The Dogo Argentino is a large, white, muscular dog that was developed in Argentina primarily for the purpose of Big-game hunting Hunting dog, including Boar hunting and Cougar; the breeder, Antonio Nores Martínez, also wanted a dog that would exhibit steadfast bravery and willingly protect its human companion to the death. It was first bred in 1928 from the Cordoba Fighting Dog along with a wide array of other breeds including, but not limited to, the Great Dane.
In 1928, Antonio Nores Martinez, a fascist medical doctor, professor and surgeon, set out to breed a elite big game hunting 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, Great Pyrenees, Pointer, Irish Wolfhound and Dogue de Bordeaux. Nores Martinez continued to develop the breed via selective breeding to introduce the desired traits.
As in the Dalmatian, white Boxer, and the white Bull Terrier, the dogo may experience pigment-related deafness. There is possibility of an approximate 10% deafness rate overall with some dogos afflicted unilaterally (one deaf ear) and some binaurally (deaf in both ears). Studies have shown that the incidence of deafness is drastically reduced when the only breeding stock used is that with bilaterally normal hearing. Hip dysplasia (canine) is also a common health concern.
