The Siberian huskies were first brought into Alaska in 1909. For centuries, they were used by the Chukchi people of the region to pull sleds and for a long time, they were also used to watch and keep reindeers together.
Siberian huskies are adapted to work in the rough conditions of Siberia; they are strong, tough, able to adapt to all conditions, and also love to work for hours. The Siberian husky is known for its high endurance and its light-weight.
Fur traders brought them to North America for races because of their great speed. One incident that helped popularize the breed was in 1925 when there was an epidemic of diphtheria in Nome, a city of Alaska where a lot of huskies brought medicine to the city.
They were also used in the Admiral Byrd's Antarctic Expeditions. The Siberian husky is now used as a companion dog but it's not their only utility.
