Sled dog
Summary
A sled dog is a dog trained and used to pull a land vehicle in harness, most commonly a sled over snow.
Sled dogs have been used in the Arctic for at least 8,000 years and, along with watercraft, were the only transportation in Arctic areas until the introduction of semi-trailer trucks, snowmobiles and airplanes in the 20th century, hauling supplies in areas that were inaccessible by other methods. They were used with varying success in the explorations of both poles, as well as during the Alaskan gold rush. Sled dog teams delivered mail to rural communities in Alaska, Yukon, Northwest Territories and Nunavut. Sled dogs today are still used by some rural communities, especially in areas of Russia, Canada, and Alaska as well as much of Greenland. They are used for recreational purposes and racing events, such as the Iditarod Trail and the Yukon Quest.
Sled dogs are used in countries such as Canada, Greenland, Siberia, Chukotka, Norway, Sweden, and Alaska.
A 2017 study showed that 9,000 years ago, the domestic dog was present at what is now Zhokhov Island, northeastern Siberia, which at that time was connected to the mainland. The dogs were selectively bred as either sled dogs or hunting dogs, implying that a sled dog standard and a hunting dog standard co-existed. The optimal maximum size for a sled dog is based on thermo-regulation, and the ancient sled dogs were between . The same standard has been found in the remains of sled dogs from this region 2,000 years ago and in the modern Siberian Husky breed standard. Other dogs were more massive at and appear to be dogs that had been crossed with wolves and used for polar bear hunting. At death, the heads of the dogs had been carefully separated from their bodies by humans and was thought to be for ceremonial reasons.
The Kungur Chronicle and the Remezov Chronicle, created at the end of the 16th century and 1703 respectively, tells about the people living along Siberian rivers, whose primary means of transport was riding on reindeer or dogs.
