In 2015, a DNA study indicated that the Siberian Husky, the Alaskan Malamute and the Alaskan husky share a close genetic relationship between each other and were related to Chukotka sled dogs from Siberia. They were separate to the two Inuit dogs, the Canadian Eskimo Dog and the Greenland Dog. In North America, the Siberian Husky and the Malamute both had maintained their Siberian lineage and had contributed significantly to the Alaskan husky, which was developed through crossing with European breeds. Several Arctic dog breeds, including the Siberian, show a significant genetic closeness with the now extinct Taimyr wolf of North Asia due to admixture. These breeds are associated with high latitudes – the Siberian Husky and Greenland Dog, also associated with arctic human populations and to a lesser extent, the Shar Pei and Finnish Spitz. There is data to indicate admixture of between 1 and 3% between the Taymyr wolf population and the ancestral dog population of these four high latitude breeds. This introgression could have provided early dogs living in high latitudes with phenotypic variation beneficial for adaption to a new and challenging environment. It also indicates the ancestry of present day dog breeds descends from more than one region. The Siberian Husky was originally developed by the Chukchi people of the Chukchi Peninsula in eastern Siberia. They were brought to Nome, Alaska in 1908 to serve as working sled dogs, and were eventually developed and used for sled dog racing.

A Siberian Husky has a double coat that is thicker than that of most other dog breeds. It has two layers: a dense, finely wavy undercoat and a longer topcoat of thicker, straight guard hairs. It protects the dogs effectively against harsh Arctic winters, and also reflects heat in the summer. It is able to withstand temperatures as low as The undercoat is often absent during shedding. Their thick coats require weekly grooming. Siberian Huskies come in a variety of colors and patterns, often with white paws and legs, facial markings, and tail tip. Example coat colors are black and white, copper red and white, grey and white, pure white, and the rare "agouti" coat, though many individuals have blondish or piebald spotting. Some other individuals also have the "saddle back" pattern, in which black tipped guard hairs are restricted to the saddle area while the head, haunches and shoulders are either light red or white. Striking masks, spectacles, and other facial markings occur in wide variety. All coat colors from black to pure white are allowed. Merle coat patterns are not permitted by the American Kennel Club (AKC) and The Kennel Club (KC). This pattern is often associated with health issues and impure breeding.

The American Kennel Club describes the Siberian Husky's eyes as "an almond shape, moderately spaced and set slightly obliquely". The AKC breed standard is that eyes may be brown, blue or black; one of each or particoloured are acceptable (complete is heterochromia). These eye color combinations are considered acceptable by the American Kennel Club. The parti color does not affect the vision of the dog.

Show quality dogs are preferred to have neither pointed nor square noses. The nose is black in gray dogs, tan in black dogs, liver in copper colored dogs, and may be light tan in white dogs. In some instances, Siberian Huskies can exhibit what is called "snow nose" or "winter nose". This condition is called hypopigmentation in animals. "Snow nose" is acceptable in the show ring.

Siberian Husky tails are heavily furred; these dogs will often curl up with their tails over their faces and noses in order to provide additional warmth. When curled up to sleep the Siberian Husky will cover its nose for warmth, often referred to as the "Siberian Swirl". The AKC recommends the tail should be expressive, held low when the dog is relaxed, and curved upward in a "sickle" shape when excited or interested in something. Females are smaller, growing to between tall at the withers and weighing between .

The Husky usually howls instead of barking. They have been described as escape artists, which can include digging under, chewing through, or even jumping over fences. The ASPCA classifies the breed as good with children. It also states they exhibit high energy indoors, have special exercise needs, and may be destructive "without proper care". A study found an association with a gene in the breed and impulsivity, inattention, and high activity. Siberian Huskies were ranked 77th out of 138 compared breeds for their intelligence by canine psychologist Stanley Coren. However, the rankings in Coren's published work utilized only one of three defined forms of dog intelligence, "Working and Obedience Intelligence", which focused on trainability—a dog's ability to follow direction and commands in a direct context, specifically by trial judges in a controlled course setting.

A 1999 ASPCA publication claims the average life span of the Siberian Husky is 12 to 14 years. Health issues in the breed are mainly genetic, such as seizures and defects of the eye (juvenile cataracts, corneal dystrophy, canine glaucoma and progressive retinal atrophy) and congenital laryngeal paralysis. Hip dysplasia is not often found in this breed; however, as with many medium or larger sized canines, it can occur. The Orthopedic Foundation for Animals currently has the Siberian Husky ranked 155th out of a possible 160 breeds at risk for hip dysplasia, with only two percent of tested Siberian Huskies showing dysplasia. Siberian Huskies used for sled racing may also be prone to other ailments, such as gastric disease, bronchitis or bronchopulmonary ailments ("ski asthma"), and gastric erosions or ulcerations. Modern Siberian Huskies registered in the US are almost entirely the descendants of the 1930 Siberia imports and of Leonhard Seppala's dogs, particularly Togo. The limited number of registered foundational dogs has led to some discussion about their vulnerability to the founder effect.

The Chukotka Sled Dog is considered the progenitor to the Siberian Husky. Developed by the Chukchi people of Russia, Chukotka sled dog teams have been used since prehistoric times to pulls sleds in harsh conditions, such as hunting sea mammals on oceanic pack ice.

From the 1890s to the 1930s, Chukotka sled dogs were actively imported into Alaska, to transport gold miners to the Yukon, first as part of the Klondike Gold Rush, then later the "All Alaska Sweepstakes", Canadian and American settlers, not well versed on Russian geography, would distinguish the Chukotka imports by referring to them as Siberian huskies as Chukotka is part of Siberia. On February 3, 1925, Gunnar Kaasen was the final musher in the 1925 serum run to Nome to deliver diphtheria serum from Nenana, over 600 miles to Nome. This was a group effort by several sled dog teams and mushers, with the longest (264 miles or 422 km) and most dangerous segment of the run covered by Leonhard Seppala and his sled team lead dog Togo. The event is depicted in the 2019 film Togo. A measure of this is also depicted in the 1995 animated film Balto; the name of Gunnar Kaasen's lead dog in his sled team was Balto, although unlike the real dog, Balto the character was portrayed as a wolf dog in the film. In honor of this lead dog, a bronze statue was erected at Central Park in New York City. The plaque upon it is inscribed, <blockquote>Dedicated to the indomitable spirit of the sled dogs that relayed antitoxin six hundred miles over rough ice, across treacherous waters, through Arctic blizzards from Nenana to the relief of stricken Nome in the winter of 1925. Endurance · Fidelity · Intelligence and who ultimately became a foundation dog for the Siberian Husky breed, through his progeny Toto, Molinka, Kingeak, Ammoro, Sepp III, and Togo II. In 1930, exportation of the dogs from Siberia was halted. The same year saw recognition of the Siberian Husky by the American Kennel Club. Seppala owned a kennel in Alaska before moving to New England, where he became partners with Elizabeth Ricker. The two co owned the Poland Springs kennel and began to race and exhibit their dogs all over the Northeast. The kennel was sold to Canadian Harry Wheeler in 1931, following Seppala's return to Alaska Their popularity was sustained into the 21st century. They were ranked 16th among American Kennel Club registrants in 2012, rising to 14th place in 2013.

Huskies were extensively used as sled dogs by the British Antarctic Survey in Antarctica between 1945 and 1994. A bronze monument to all of BAS's dog teams is outside its Cambridge headquarters, with a plaque listing all the dogs' names. In 1960, the US Army undertook a project to construct an under the ice facility for defense and space research, Camp Century, part of Project Iceworm involved a 150+ crew who also brought with them an unofficial mascot, a Siberian Husky named Mukluk. Due to their high popularity combining with their high physical and mental needs, Siberians are abandoned or surrendered to shelters at high rates by new owners who do not research them fully and find themselves unable to care for them. Many decide on the breed for their looks and mythos in pop culture, and purchase pups from backyard breeders or puppy mills who do not have breeder return contracts that responsible breeders will, designed to keep the breed out of shelters. Sled dogs that were bred and kept by the Chukchi tribes of Siberia were thought to have gone extinct, but Benedict Allen, writing for Geographical magazine in 2006 after visiting the region, reported their survival. His description of the breeding practiced by the Chukchi mentions selection for obedience, endurance, amiable disposition, and sizing that enabled families to support them without undue difficulty. Huskies are also kept as pets, and groups work to find new pet homes for retired racing and adventure trekking dogs. Many huskies, especially Siberian Huskies, are considered "working dogs" and often are high energy. Exercise is extremely important for the physical and mental health of these kinds of dogs and it can also prompt a strong bond between the owner and dog. Since many owners now have huskies as pets in settings that are not ideal for sledding, other activities have been found that are good for the dog and fun for the owner. Rally Obedience: Owners guide their dogs through a course of difficult exercises side by side. There are typically 10 to 20 signs per course and involve different commands or tricks. Agility Training: A fast paced obstacle course that deals with speed and concentration. Dogs race the clock to complete the course correctly. Skijoring is an alternative to sled pulling. The owner would be on skis while the dog would pull via a rope connected between the two. Dog hiking is an alternative for owners who live near or are able to travel to a trail. The owner travels with their dogs along trails in the wilderness. This activity allows the owner and dog to gain exercise without using the huskies' strong sense of pulling. Some companies make hiking equipment especially for dogs in which they may carry their own gear, including water, food, and bowls for each. Carting, also known as dryland mushing or sulky driving, is an urban alternative to dog sledding. Here, the dog can pull a cart that contains either supplies or an individual. This is also an acceptable way to use a dog's natural inclination to pull in an effective way. These carts can be bought or handmade by the individual. Bikejoring is an activity where the owner bikes along with their dog while they are attached to their bike through a harness which keeps both the dog and owner safe. The dog or team of dogs can be attached to a towline to also pull the biker.

A bronze statue of Balto that has been displayed in New York City's Central Park since 1925 is one of the park's enduringly popular features. The Twilight Saga, which features werewolves and the television series Game of Thrones spurred a huge uptick in demand for Siberian Huskies as pets, followed by a steep increase of their numbers at public shelters. Even though the animal actors were not Siberian Huskies, people were acquiring Siberian Huskies because they looked similar to the fictional direwolf characters depicted in the show. Two of the show's stars pleaded with the public to stop acquiring the dogs without first researching the breed. The phrase three dog night, meaning it is so cold you would need three dogs in bed with you to keep warm, originated with the Chukchi people of Siberia, who kept the Siberian husky landrace dog that became the modern purebred breed called the Siberian Husky. The World War II Allied invasion of Sicily in 1943 was called "Operation Husky". Several purebred Siberian Huskies portrayed Diefenbaker, the "half wolf" companion to RCMP Constable Benton Fraser, in the CBS/Alliance Atlantis TV series Due South. Siberian Huskies are the mascots of the athletic teams of several schools and colleges, including St. Cloud State University (St. Cloud State Huskies, Blizzard), Northern Illinois University (Northern Illinois Huskies, Victor), the University of Connecticut (Connecticut Huskies, Jonathan), Northeastern University (Northeastern Huskies, Paws), the Michigan Technological University (Michigan Tech Huskies, Blizzard), University of Washington (Washington Huskies, Harry), Houston Baptist University (Houston Baptist Huskies, Kiza the Husky), and Saint Mary's University (Saint Mary's Huskies) and George Brown College (Toronto, Ontario).
