Dogo Argentino

The Dogo Argentino also known as the Argentine Mastiff is a large, white, muscular 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 to the death. It was first bred in 1928, from the Cordoba Fighting Dogalong with a wide array of other breeds including, but not limited to, the Great Dane.

The Dogo Argentino is a large white short-coated dog with muscular and strong body that rarely has any markings (any type of marking or spot on the coat is considered a flaw).
