Mushing

Mushing is a sport or transport method powered by dogs, either by cart, pulk, dog scootering, sled dog racing, skijoring, freighting, and weight pulling. More specifically, it implies the use of one or more dogs to pull a sled, most commonly a specialized type of dog sled on snow, or a rig on dry land.

The practice of using dogs to pull sleds dates back to at least 6000 BC. Remnants of sleds and harnesses has been found with canine remains in Siberia which carbon-dated to 7800–8000 years ago. Native American cultures also used dogs to pull loads.^{[citation needed]}

For the better part of the 1600s, the Iroquois and French clashed in a series of attacks and reprisals. For this reason, Samuel de Champlain arranged to have young French men live with the natives, to learn their language and customs and help the French adapt to life in North America. These men, known as [[Coureur des bois|coureurs des bois (runners of the woods]]), were the first European mushers in North America, extended French influence south and west and in 1609, New France controlled all the Canadian Shield. In 1680, the intendant of New France, Jacques Duchesneau de la Doussinière et d'Ambault, estimated that there was not one family in New France who did not have a "son, brother, uncle or nephew" among the coureurs des bois. During the winter, sled became the ordinary transportation in the north of New France.

In 1760, the British Army completed the conquest of Canada and gained control of the Canadian Shield. Many coureurs des bois accepted British rule and continued to use the sled dog. The French term Marche! became Mush! in English.

During the Klondike Gold Rush, many prospectors came in the Yukon with sled dogs. This "Last Great Gold Rush" has been immortalized by American author Jack London in The Call of the Wild. Sled-dog became the common mode of transportation in Yukon and in the new US Territory of Alaska.

In 1911, Norwegian explorer Roald Amundsen used sled dogs in a race to become the first person to reach the South Pole. He succeeded, while his competitor Robert Falcon Scott, who had instead used Siberian ponies, died.

By the time of the First World War, mushing had spread to European countries such as Norway, where dog sleds were used for nature tours, as ambulances in the woodlands and mountains, and to bring supplies to soldiers in the field.

During the 1925 serum run to Nome, 20 mushers and about 150 sled dogs relayed diphtheria antitoxin 674 miles (1,085 km) by dog sled across the U.S. territory of Alaska in five and a half days, saving the small city of Nome and the surrounding communities from an incipient epidemic.
