Husky is a general term for sled dogs used in the northern region, which is different from other sled dogs in their fast pulling style. They are the most versatile hybrid of the fastest dogs. In contrast, Alaskan sled dogs are used to pull heavy loads. Huskies are used in sled dog racing. In recent years, the company has also promoted dog sled tours to snow explorers. Today, the Eskimo is also kept as a pet, with groups working together to find new pet homes for retired racing and adventure dogs.

Husky was originally a local breed raised by indigenous people in the Arctic.

Examples of these modern local breeds have been selectively bred and registered as modern purebred in various kennel clubs, including Siberian and Labrador sled dogs. Sakhalin Husky is a Japanese sled dog related to Japanese Spitz and Akita dogs.

The Mackenzie River Husky is a subtype, which refers to different dog populations in Alaska and Canada.

Almost all dogs are genetically related to gray wolves because of mixing. However, due to the mixture, some Arctic dog breeds also show genetic relationships with the now extinct Tamil wolves in North Asia: Siberian sled dogs and Greenland dogs (also historically related to the Arctic population), and to a lesser extent, with sandpipers and Finnish boehmers. The mix of Greenland dogs shows that the best shared material is 3.5%. However, the proportion of ancestors is between 1.4% and 27.3%, which is consistent with the data, indicating that there is a mixture between the ancestors of Tamil wolf and the four high latitude breeds.

This kind of infiltration can provide phenotypic variation for early dogs living in high latitude area, which is beneficial to adapt to the new challenging environment, thus greatly promoting the development of hoarseness. This also shows that the bloodline of today's dog breeds comes from many regions.

The Eskimo is full of energy and athletic ability. They usually have thick double coats, which can be gray, black, copper red or white. Their eyes are usually light blue, although they can also be brown, green, blue, yellow or a different color. Compared with most other breeds, Eskimos are more likely to develop some degree of uveitis.
