[1] 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.

[2] The origins of the Argentine polar dog can be traced back to 1949, when Colonel Hernán Pujato approached President Juan Perón with a proposal that sought to bring Argentina closer to its Antarctic territorial claims by establishing the Instituto Antártico Argentino and other science-oriented bases with year-round populations.

Perón's interest led to Pujato visiting North America and taking a "Polar Survival Course" required by the United States Army in both Alaskan and Greenlandic territories.

The variables that caretakers considered included, but were not limited to, rest periods, pregnancy, gastrointestinal issues, and dog's last activity and its duration.

Over time, Pemmican began to be supplemented by and/or mixed with seal meat, which was greatly enjoyed by the dogs and provided extra calories that helped them remain strong.

A well-trained Argentine polar dog was expected to have a working day of approximately 8 to 9 hours, hauling a weight similar to their own at a moderate pace, depending on the terrain.

The tails were arched over their backs, which helped to provide an additional protection from the cold as they rested, bent over their bodies and reaching their faces.

[3] In August 1991, the Protocol on Environmental Protection to the Antarctic Treaty required that all parties with territorial pretensions remove any fauna or flora they had introduced to the continent by 1 April 1994.

[5] That year, as a member of the Antarctic Treaty, Argentina relocated all 22 dogs living in the San Martín Base to a corps of the Argentine National Gendarmerie in Puente del Inca, in Mendoza.

In February 1993, the last 13 dogs remaining on the continent, stationed at the Esperanza Base, were relocated to another corps of the Argentine National Gendarmerie in the city of Ushuaia, in Tierra del Fuego.
