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 and puma; the breeder, Antonio Nores Martinez, 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.

Appearance

The Dogo Argentino is a large white short-coated dog with very muscular and strong body that rarely has any markings (any type of marking or spot on the coat is considered a flaw.
Height: From 24 ½ to 27 inches inches (females) or 25 to 29 inches (males), measured at the withers. Weight: From 90 to 130 pounds. The length of the body is just slightly longer than the height, but female dogs may be somewhat longer in body than male dogs. The length of the front leg (measured from point of elbow to the ground) is approximately equal to one-half of the dog's height at the withers. The head has a broad, slightly domed skull and the muzzle is slightly higher at the nose than the stop, when viewed in profile. The tail is set low, thick at the base and tapers to a point. It has been described as looking similar to an American Bulldog but very tall and a solid white American Pit Bull Terrier.

Health

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 bilaterally (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.

Temperament

Dogos are big-game hunters and are sometimes trained for search and rescue, police assistance, and military work.
The Dogo Argentino was specifically bred to be fierce hunters, but then to go home to the hunters families and be gentle with the family.
Dogo Argentinos are protective of what they perceive as their territory and will guard it against any intruder. They get along with other dogs as long as they have been properly socialized, but will usually not tolerate another dog trying to assert dominance over them, therefore they might not coexist peacefully with another strong breed. The Dogo has a life expectancy of nine (9) to twelve (12) years.
