About the Argentine polar dog
The Argentine polar dog is an extinct breed of dog. It was created by the Argentine Army to haul freight around its bases in Antarctica. The breed was a cross between a Spitz, which were traditionally used as sled dogs, and several other breeds, including the Alaskan Malamute, the Siberian Husky, the Greenland Dog, and the Samoyed. The practice of breeding Argentine polar dogs came to an end in 1991, when Article 4 of the Antarctic Treaty forced the removal of all non-native species from the continent.
