I cheated on this one. Alaskan Husky is not a breed, but a category or type of dog.
Alaskan Malamute was originally bred to be used as an Alaskan sled dog. It is generally a large and domesticated dog.
Canadian Eskimo Dog is an Arctic breed and is considered to be the oldest and rarest of the remaining purebred indigenous domestic canines.
Chinook is a rare New England sled dog breed of "in-between" type, neither a sprinter nor an endurance freighter; the original lead dog "Chinook" on whom the breed is based was a mixture from working sled dog lines and of a more mastiff-type build than most sled dogs, and the breed varies in appearance much more than most sled dog breeds and often superficially resembles a yellow German Shepherd Dog mix.
Eurohound is a crossbred dog, a mix between the Alaskan Husky and the Pointer. It has both the Alaskan Husky's sledding ability and the Pointer's enthusiasm and athleticism. It is one of the most formidable sprint-racing sled dogs in the world.
Greenland Dog is a large breed of husky-type dog kept as a sled dog and also used for hunting polar bear and seal.
Greyster sled dog type bred in Norway.
Labrador Husky was bred as a strong, fast, working sled dog and originated in Canada.
Mackenzie River Husky is built for heavy freighting in single file through deep snow. Less a specific breed than a certain set of varieties of sled dog types from a specific geographic area, a mix of Arctic and subarctic sled dogs.
Sakhalin Husky is rarely used and usually lives in Japan.
Samoyed is a pure or mostly-white spitz that was used for herding reindeer as well as pulling sleds.
Seppala Siberian Sleddog is active and energetic, sharing the same ancestral base as the Siberian Husky.
Siberian Husky originated in Siberia. They were originally meant to be sled dogs, but nowadays are mainly family pets and show dogs.
Tamaskan Dog originated in Finland and bred to look like wolves. Not bred specifically for (though still capable of) sledding work, it excels in agility, obedience, and working trials.
Utonagan and Northern Inuit Dog are bred to resemble wolves, but are mixes between the Alaskan Malamute, German Shepherd, and Siberian Husky.
There were ten distinct husky breeds differentiated by region, height/weight and color: the Husky proper (recognised by the American Kennel Club under the name of Eskimo), the Alaskan Malamute, the Toganee, the Mackenzie River Husky, the Timber-Wolf Dog, the West Greenland Husky, the East Greenland Husky, the Baffinland Husky, the Chuchi (recognised by the American Kennel Club as the Siberian Husky), and the Ostiak.
The Husky or Eskimo dog is rare outside of the Northwest Territories. These are mostly used by trappers, explorers, Eskimos and Indians; the Hudson Bay traders, Royal Canadian Mounted Police, lumber-jacks, doctors, priests and others generally use what the Indians call the white dogs, or crossbred dogs which are half Husky and half Hound, Great Dane, Newfoundland or any other type that is handy. 
The Toganee and Mackenzie River Dogs were closely related to the true Husky and sometimes interbred. The Toganee had longer legs while the Mackenzie River Dog had a longer coat. The Timber-Wolf Dog of the Yukon basin was a first-cross between the true Husky and the timber-wolf and used as a leader or "king" dog. The Baffinland Husky differed from the true Husky in having a black coat with white markings. The West Greenland Husky and the slightly smaller East Greenland Husky both had timber-wolf blood and were sometimes crossed with the Baffinland Husky. The East Greenland Husky (also called the Angmagssalik Husky) was considered the oldest and least diluted type. The comparatively small Ostiak or West Siberian Husky was used not only for sled hauling but also in hunting elk, bear and wolf. The tenth recognised type was the Chuchi (Siberian Husky) first imported into Alaska in 1909.
Hey ,Salzer, I watched the movie and they said they were just Snow Dogs. I thought about that because they all looked so different. I had wondered what they were Huskey or mixed with a wolf. That is a good question.
