The Argentinean Mastiff, otherwise known as the Dogo Argentino, is a big game hunter developed in Argentina. The breed was created to hunt large animals such as cougars and wild boar which can weigh up to 600 pounds. The base of the breed is the Cordoba Fighting Dog, which is currently extinct. It was crossed with many breeds including: Boxers, Bull Terriers, Bulldogs, Great Danes, Pointers, Spanish Mastiffs, Great Pyrenees, Irish Wolfhounds and Dogues de Bordeaux. The breed standard was written in the 1920s and the breed was introduced to the U.S. in the early 1970s. Today the breed is still used to hunt, but it is also used for tracking, search and rescue work, police work, military work, Schutzhund training, and even as a family pet or a guide dog.
The Argentinean Mastiff is a large, muscular, athletic dog. It stands 23 to 27 inches tall and has a short white coat. Its shape is somewhat rectangular; it generally weighs between 75 and 90 pounds. It has a broad skull, powerful muzzle, close-lying ears and a fairly short tail.
The breed is affectionate, and tends to generally avoid aggression, as this trait has been bred out specifically. The Argentinean Mastiff loves attention and typically gets along with children as well as other pets. Although it is usually not an aggressive breed, it will fearlessly guard its owner and its territory, and assertive breeds may not bode well with the Argentinean Mastiff.
The breed typically hunts in a pack. In order to be a successful pack mate, it must be socialized and trained at an early age. The breed has occasionally been interbred with Pit Bulls for fighting purposes.
The Argentinean Mastiff only has a few health issues such as deafness and hip dysplasia.
