Argentine Dogo

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.
Dogo Argentinos have been bred specifically to allow better socialization with other dogs and are well suited for group environments. They get along with other pets in most rural and urban settings ranging from a complete outdoor farm dog to urban housing with a small yard, to crowded apartment buildings. Because aggressive traits are purposely bred out, attacks on humans or other pets are extremely rare. The Dogo has a life expectancy of 10 to 12 years.
