Reference excerpt

Husky is a general term for a type of dog used in the polar regions, primarily and specifically for work as sled dogs. It also refers to a traditional northern type, notable for its cold-weather tolerance and overall hardiness. Modern racing huskies that maintain arctic breed traits (also known as Alaskan huskies) represent an ever-changing crossbreed of the fastest dogs. Huskies have continued to be used in sled-dog racing, as well as expedition and trek style tour businesses, and as a means of essential transportation in rural communities. Huskies are also kept as pets, and groups work to find new pet homes for retired racing and adventure-trekking dogs.

Etymology

The term "husky" first came into usage in the mid to late 1700s. At this time, "Esquimaux" or "Eskimo" was a common term for pre-Columbian Arctic inhabitants of North America. Several dialectal permutations were in use including Uskee, Uskimay and Huskemaw. Thus, dogs used by Arctic people were the dogs of the Huskies, the Huskie's dogs, and eventually simply the husky dogs. Canadian and American settlers, not well versed on Russian geography, would later extend the word to Chukotka sled dogs imported from Russia, thus giving rise to the term Siberian husky.

History

Nearly all dogs' genetic closeness to the grey wolf is due to admixture. However, several Arctic breeds also show a genetic closeness with the now-extinct Taimyr wolf of North Asia due to admixture: the Siberian Husky and Greenland Dog (which are also historically associated with Arctic human populations) and to a lesser extent, the Shar Pei and Finnish Spitz. An admixture graph of the Greenland Dog indicates a best-fit of 3.5% shared material; however, an ancestry proportion ranging between 1.4% and 27.3% is consistent with the data and indicates admixture between the Taimyr wolf and the ancestors 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, contributing significantly to the development of the husky. It also indicates that the ancestry of present-day dog breeds descends from more than one region.

Characteristics Huskies are energetic and athletic. They are distinguished by their hardiness and cold-weather tolerance, in contrast to many modern sprint sled dogs derived from hound and pointer crossbreeds and purebred sprinting dogs which do not have or retain these qualities. Likewise, they are distinguished from laika, as they were not developed for the primary purpose of hunting game and prey animals. Huskies typically have a thick double coat that may come in a variety of colors. The double coat generally protects huskies against harsh winters and, contrary to what most believe, they can survive in hotter climates. During the hotter climates, huskies tend to shed their undercoat regularly to cool their bodies. In addition to shedding, huskies control their eating habits based on the season; in cooler climates, they tend to eat generous amounts, causing their digestion to generate heat, whilst in warmer climates, they eat less. Their eyes are typically pale blue, although they may also be brown, green, blue, yellow, or heterochromic. Huskies are more prone to some degree of uveitis than most other breeds.

Breeds This is a list of dog breeds which contain "husky" in their name. To see a complete list of sled breeds, see Sled dog.

Alaskan husky

The most commonly used dog in dog sled racing, the Alaskan husky is a mongrel bred specifically for its performance as a sled dog. The modern Alaskan husky reflects 100 years or more of crossbreeding with English Pointers, German Shepherd Dogs, Salukis and other breeds to improve its performance. They typically weigh between 18 and 34 kg (40 and 75 lb) and may have dense or sleek fur. Alaskan huskies bear little resemblance to the typical husky breeds they originated from, or to each other.

Labrador Husky

The Labrador Husky originated in the Canadian region of Labrador. The breed probably arrived in the area with the Inuit who came to Canada around 1300 AD. Despite the name, Labrador Huskies are not related to the Labrador Retriever, but in fact are most closely related to the Canadian Eskimo Dog. There are estimated to be 50–60 Labrador Huskies in the world.

Mackenzie River Husky

The term Mackenzie River husky describes several overlapping historical populations of Arctic and sub-Arctic sled dog-type dogs, none of which constituted a breed. Dogs from the Yukon Territory were crossed with large European breeds such as St. Bernards and Newfoundlands to create a powerful freighting dog capable of surviving harsh arctic conditions during the Klondike Gold Rush.

Sakhalin Husky

The Sakhalin Husky is a critically endangered landrace and sled laika associated with Sakhalin Island and adjacent areas. They are also known as Karafuto Ken, Sakhalin Laika, or Gilyak Laika. While bred primarily as a sled dog, Sakhalin Huskies are also used for hunting bear and fishing. There are approximately 20 Sakhalin Huskies remaining on Sakhalin Island.

Siberian Husky

The Siberian Husky is smaller than the similar-appearing Alaskan Malamute. They are descendants of the Chukotka sled dogs bred and used by the native Chukchi people of Siberia, a people of Paleosiberian origin, around the year 2000 BC. Imported to Alaska in the early 1900s, they were used as working dogs and racing sled dogs in Nome, Alaska throughout the 1910s, often dominating the All-Alaska Sweepstakes. They later became widely bred by recreational mushers and show-dog fanciers in the U.S. and Canada as the Siberian Husky, after the popularity garnered from the 1925 serum run to Nome. Siberians stand 20–23.5 inches, weigh between 35 and 60lbs (35-50 for females, 45-60 for males), and have been selectively bred for both appearance and pulling ability. They are still used regularly today as sled dogs by competitive, recreational, and tour-guide mushers.

Worked examples

Example 1 — a first encounter with Husky

Start with the simplest possible case. Write down what Husky claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Husky before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Husky ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Husky

In research: Husky appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Husky in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Husky is common in secondary-school and first-year university syllabi. It links to neighbouring topics Dog types, Sled dogs, so understanding it makes those chapters shorter.
In everyday life: Look for Husky outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
