The Dogo Argentino is a large, white, muscular breed of dog that was developed in Argentina primarily for the purpose of big-game hunting, including wild boar. The breeder, Antonio Nores Martínez, also wanted a dog that would exhibit steadfast bravery and willingly protect its human companion. It was first bred in 1928 from the Cordoba Dog, along with a wide array of other breeds, including the Great Dane. This dog breed is capable of taking down mountain lions. While the Argentine Dogo was bred primarily from the extinct Cordoba Dog, it was bred to be a cooperative hunter, i.e. to accompany other catch dogs and bay dogs on the hunt without fighting with the other dogs.
