The Alaskan husky is a breed of medium-sized working sled dog, developed specifically for its performance as such. [1] [2] [3]
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 such as the Iditarod Trail Sled Dog Race, [4] the Yukon Quest, [5] and the Finnmarkslopet.
The Alaskan husky is not an officially recognized breed by any kennel club, nor does it have a formal breed standard. [6] Unlike breeds developed for the show ring, the 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. [7] [8] As a result of this specific and mindful performance-only based breeding, DNA studies show that Alaskan Huskies share a genetic signature and indeed can be identified accurately on DNA breed tests. [9]
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. [10] Some Alaskan husky lines have very traditional husky spitz-like features with pointed ears and curled tails, while other lines more closely resemble their hound or gundog heritage with tipped or floppy ears, straight tails and tucked up sighthound-like loins. [11] [12] As they are not bred with conformation in mind, cosmetic features are not a consideration for breeding, and these features instead tend to follow the purpose of the dog's intended style of sled work.
Generally Alaskan huskies are taller than Siberian Huskies and are lighter in build than Alaskan Malamutes, both of whom they share lineage with and are descended from. On average they stand between 20 and 26 inches (51 and 66 cm) and weigh between 35 and 75 pounds (16 and 34 kg). [11] [12] Tough feet are an important feature and desirable trait for breeding consideration. As with their build, the Alaskan husky's coat can vary greatly; they usually have double coats with all colors and patterns of colors seen within various lines. [11] [12] Distance-type Alaskan huskies often have denser double coats to better contend with cold temperatures and harsh wind, whereas sprint lines have shorter coats to allow for greater heat dissipation during races at high speeds.
It is common for distance-type Alaskan huskies to be outfitted with dog coats and dog booties during long expeditions and races, in order to regulate temperature and protect the dog's feet from ice and rough terrain. [5] The use of dog coats has become more common into the late 20th and early 21st centuries as even the distance lines have been bred for greater speed, sacrificing some of the heavier and more dense protective double-coat of their Arctic breed ancestors.
As European traders and settlers arrived in Alaska they sought local entertainment, and turned to racing the local means of transportation, sled dogs. [10] Indigenous dogs found throughout Alaska were renowned for their great strength and stamina, but lacked speed, so various outcrosses to fleeter Old World breeds were utilized to produce faster-running dogs, including Siberian imports who dominated local organized races in Alaska. [13] Since the beginning of the 20th century, various breeders have turned to various outcrosses to produce different lines of racing dogs. Most lines today contain some form of traditional husky heritage in their bloodlines, Alaskan Malamutes and Siberian Huskies being the most common, although Mackenzie River huskies, Greenland Dogs, and Samoyeds have also been utilized. [10] [12]
In the latter half of the 20th century the primary use of sled dogs shifted from utility to sport, particularly career competitive sled dog racing. In order to facilitate greater speed for racing sport, various breeds of gundogs and sighthounds have now been bred into Alaskan husky lines, including Pointers, Greyhounds, German Shorthaired Pointers, Salukis, Borzois, Labradors and Setters; some breeders have even used wolves at various points. [10] [12] [11]
Genetic studies indicate that the Alaskan Husky originates from pre-Colonial North American Arctic village dogs (including precursors to the Alaskan Malamute) and Siberian imports (precursors to the Siberian Husky), crossbred with European breeds such as Pointers, German Shepherd Dogs, and Salukis to improve its performance. [9] [8]
In 2015, a DNA study indicated that the Alaskan husky, the Siberian Husky, and the Alaskan Malamute 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. 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. [8]
Other breeds identified as having contributed to the Alaskan husky sled dog gene pool include Pointers, and a number of other non-arctic breeds by breed and type group. Genetic variation in the Alaskan husky has been analyzed based on the groupings of two purpose-driven distinct populations within the Alaskan sled dog gene pool: a distance group, and a sprint group: [9]
The Alaskan husky has selectively been bred specifically for its athletic performance. [14] [5] As such, its level of athletic ability, as well as anabolic efficiency are far greater than the average domesticated dog, especially in endurance feats. Distance-specialist Alaskan huskies out-speed most animals and all other types of sled dogs when running distances of 50 miles or greater, even while pulling moderately sized loads. [5] Studies on the metabolic capabilities in working Alaskan husky sled dogs reveal that their system transitions to utilization of low-glucose energy sources (from high-glycogen carbohydrates) early on during long periods of travel, and their reliance on these low-glucose fuels (such as those higher in fats and proteins) continue and even extend to become more pronounced after working for longer periods. [14] A good appetite is a highly desirable trait, and is emphasized in breeding choices. [15]
Like most working sled dogs, Alaskan huskies are capable of pulling far greater than their own body weight in load while in harness. Sprint teams of Alaskan huskies are capable of speeds of up to 28 mph (45 km/h), [16] whereas distance-specialist teams have completed 938 mile (1510 km) races in just 8 days, 3 hours, 40 minutes, and 13 seconds with time including 40 hours of mandatory rests and other routine rests on the trail. [17]
As specifically purposed working sled dogs, Alaskan huskies can be subject to climate or work-specific health conditions that any sled dogs may experience, such as temperature-related bronchitis or bronchopulmonary ailments, also known as "ski asthma". [18]
In 2020, the largest study of "canine hematologic and serum biochemical analytes" to date was published, including within it the largest data set of healthy athlete dogs; the dogs of reference were 4,804 sled dogs training for the Iditarod Trail Sled Dog Race, the overwhelming majority of which were Alaskan huskies. [19] The study found that anti-aging and anti-inflammatory biochemical levels in the dogs increased over time and with training, enhancing the dogs' physical and mental abilities until an average of 6.6 years of age. Despite noted differences in sex, genetic, and age groups in other areas, they were not statistically significant and were outside the scope of the study, making them scientifically inconclusive despite their observance. [19]
The behaviors and temperament of the Alaskan husky can vary greatly due to the wide range of genetic backgrounds and bred-purposes within the breed. As with all sled dogs, a desire to pull and run are essential and are of high priority in decisions of breeding. Mental soundness is also important due to the need for dogs to be in close quarters with other dogs while hooked in the team, handled by people for proper care and transportation, and for dogs on racing teams to perform under environments which include trails crowded with spectators and other dog teams. [15]
As dogs selectively-bred for their ability as working sled dogs without direct physical feedback from the driver, intelligence and problem solving are highly desired in a specimen and are often marks of talented lead dogs, which are often those with the highest consideration as breeding prospects. Dogs are expected to read the trail and situation through instincts and experience, and thus superior cognitive abilities are often bred into Alaskan husky lines in tandem with physical athletic attributes. [20]
The Siberian Husky is a medium-sized working sled dog breed. The breed belongs to the Spitz genetic family. It is recognizable by its thickly furred double coat, erect triangular ears, and distinctive markings, and is smaller than the similar-looking Alaskan Malamute.
A dog breed is a particular type of dog that was purposefully bred by humans to perform specific tasks, such as herding, hunting, and guarding. Dogs are the most variable mammal on Earth, with artificial selection producing upward of 360 globally recognized breeds. These breeds possess distinct traits related to morphology, which include body size and shape, tail phenotype, fur type, etc, but are only one species of dog. Their behavioral traits include guarding, herding, and hunting, and personality traits such as hyper-social behavior, boldness, and aggression. Most breeds were derived from small numbers of founders within the last 200 years. As a result of their adaptability to many environments and breedability for human needs, today dogs are the most abundant carnivore species and are dispersed around the world.
The Iditarod Trail Sled Dog Race, more commonly known as The Iditarod, is an annual long-distance sled dog race held in Alaska in early March. It travels from Anchorage to Nome. Mushers and a team of between 12 and 16 dogs, of which at least 5 must be on the towline at the finish line, cover the distance in 8–15 days or more. The Iditarod began in 1973 as an event to test the best sled dog mushers and teams but evolved into today's highly competitive race.
A sled dog is a dog trained and used to pull a land vehicle in harness, most commonly a sled over snow.
The Alaskan Malamute is a large breed of dog that was originally bred for its strength and endurance, to haul heavy freight as a sled dog. It is similar to other arctic breeds such as the husky, the spitz, the Greenland Dog, Canadian Eskimo Dog, the Siberian Husky, and the Samoyed.
Sled dog racing is a winter dog sport most popular in the Arctic regions of the United States, Canada, Russia, Greenland and some European countries. It involves the timed competition of teams of sled dogs that pull a sled with the dog driver or musher standing on the runners. The team completing the marked course in the least time is judged the winner.
Mackenzie River husky describes several overlapping historical populations of Arctic and sub-Arctic sled dog originally bred to support fur traders for Hudson's Bay Company and later prospectors during the Klondike Gold Rush. A mixture of native sled dogs and European freighting dogs, Mackenzie River huskies were prized for their ability to haul heavy loads long distances in the snow with minimal care. Since the advent of modern mechanized travel in the Arctic, moving cargo by dogsled has become nearly obsolete and only small populations of these dogs still exist.
A dog sled or dog sleigh is a sled pulled by one or more sled dogs used to travel over ice and through snow. Numerous types of sleds are used, depending on their function. They can be used for dog sled racing. Traditionally in Greenland and the eastern Canadian Arctic the Inuit had the dogs pull in a fan shape in front of the sled, while in other regions, such as Alaska and the western part of Northern Canada the dogs pull side by side in pairs.
Husky is a general term for a dog used in the polar regions, primarily and specifically for work as sled dogs. It refers to a traditional northern type, notable for its cold-weather tolerance and overall hardiness. Modern racing huskies that maintain arctic breed traits represent an ever-changing crossbreed of the fastest dogs.
The Greenland Dog is a large breed of husky-type dog kept as a sled dog. They were brought from Siberia to North America by the Thule people 1,000 years ago, along with the Canadian Eskimo Dog. The Canadian Eskimo Dog is considered the same breed as the Greenland Dog since they have not yet diverged enough genetically to be considered separate breeds, despite their geographic isolation.
Dog crossbreeds are dogs which have been intentionally bred from two or more recognized dog breeds. They are not dogs with no purebred ancestors, but are not otherwise recognised as breeds in their own right, and do not necessarily breed true.
A Eurohound is a type of dog bred for sled dog racing. The eurohound is crossbred from the Alaskan husky and any of a number of pointing breeds ("pointers"), but most often the German Shorthair Pointer,
The Canadian Eskimo Dog or Canadian Inuit Dog is a breed of working dog from the Arctic. Other names include qimmiq or qimmit. The Greenland Dog is considered the same breed as the Canadian Eskimo Dog since they have not yet diverged enough genetically to be considered separate breeds, despite their geographic isolation.
Leonhard "Sepp" Seppala was a Norwegian-Kven-American sled dog breeder, trainer and musher who with his dogs played a pivotal role in the 1925 serum run to Nome, and participated in the 1932 Winter Olympics. Seppala introduced the work dogs used by Native Siberians at the time to the American public; the breed came to be known as the Siberian Husky in the English-speaking world. The Leonhard Seppala Humanitarian Award, which honors excellence in sled dog care, is named in honour of him.
The Alaskan Klee Kai is a spitz-type breed of dog, developed in the late 20th century as a companion-sized dog resembling the larger Alaskan Malamute and Siberian Husky. It is an energetic, intelligent dog with an appearance that reflects its northern heritage. Bred in three sizes, its weight range is from 5 to 22 pounds as an adult, depending on whether its a standard, toy, or miniature.
The Sakhalin Husky is a critically endangered landrace and sled laika associated with Sakhalin Island and adjacent areas. They are also known Karafuto Ken, Sakhalin Laika, or Gilyak Laika. While bred primarily as a sled dog, Sakhalin Huskies are also used for hunting bear and fishing. In 1989, there were approximately 20 Sakhalin Huskies remaining on Sakhalin Island.
Tamaskan dogs are a breed of dog from Finland that have been selectively bred to resemble a wolf or wolfdog. Although their exact origins are uncertain, these mixbreed dogs were primarily arctic breed crosses of Alaskan Husky, Alaskan Malamute, Canadian Eskimo Dog, German Shepherd, Labrador Husky, and Siberian Husky. Tamaskans are not recognized as a breed by the Fédération Cynologique Internationale but are recognized as a breed by the American Rare Breed Association.
The Greyster is a type of sled dog bred for sled dog racing, especially dryland sports like canicross and bikejoring. The greyster is crossbred from the Greyhound and the German Shorthair Pointer.
The Chukotka Sled Dog is the aboriginal spitz breed of dog indigenous to the Chukchi people of Russia.
