Siberian Husky, a thickly coated, compact sled dog of medium size and great endurance, was developed to work in packs, pulling light loads at moderate speeds over vast frozen expanses. Sibes are friendly, fastidious, and dignified. The graceful, medium-sized Siberian Husky's almond-shaped eyes can be either brown or blue.

Alaskan huskies are the most commonly used type of dog for competitive sled dog racing, both in short-distance sprint racing as well as long-distance expedition races. Alaskan husky is instead a product of careful selection for desirable sled dog traits from various other breeds, such as aptitude for pulling, endurance, speed, intelligence, appetite, and tolerance of extreme weather.

Siberians are known for their powerful but seemingly effortless gait. Tipping the scales at no more than 60 pounds, they are noticeably smaller and lighter than their burly cousin, the Alaskan Malamute.

The Alaskan husky is an incredibly athletic dog variety, and as a dog crossbreed their appearance can vary markedly, although various lines have been bred for multiple generations and breed very true to that line's type.
