Breed Appearance The Argentinean Mastiff (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 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 Dog along with a wide array of other breeds including, but not limited to, the Great Dane.

History This breed was created in Argentina by the Martinez brothers in the
early twentieth century. The root stock was the Fighting Dog of
Cordoba, a ferocious mastiff. As the breed was developed it was
crossed with the Spanish Mastiff, the Great Pyrenees, the Great
Dane, the Boxer, mastiffs, the Bulldog, pointers, and the Irish
Wolfhound. The result was a versatile breed that could be used for
hunting, fighting, guard duties, and more. The first standard was
written in 1928 and approved by the Argentina Kennel Club in 1965.
In 1973, the FCI established a standard for the breed, and, in 1975,
officially recognized the first and only breed ever developed in
Behavior This is a very robust, active, energetic, agile, courageous breed.
The Argentinean Mastiff is calm, peaceful, affectionate, and docile. He
is very sociable and needs to stay close to his owner. He rarely
barks. This breed is aggressive and dominant with other dogs, and is
fearsome indeed when defending his owner's property. Firm training
is required, but be gentle with this sensitive dog.
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. Hip dysplasia is also a common health concern.
Advice The Argentinean Mastiff can adjust to life in an apartment if he can
get out two or three times each day and get plenty of exercise. He
should be outdoors as much as possible. Brushing once or twice per
week and bathing two or three times per year is recommended. It is
necessary to clean his eyes regularly to avoid streaks.
