The Siberian Husky is an ancient breed that has a long history of helping mankind. The breed is believed to have started with the Chukchi tribe of Siberia, though various other tribes are occasionally credited with its development. The Siberian Husky has been used for a number of purposes throughout history, including herding of reindeer, pulling sleds and keeping children warm. This breed was made famous in 1925 when they were used to deliver diphtheria serum after a city was stricken by an epidemic. They were also used for transporting various other medications to the ill. The Siberian Husky found its way to America in 1909 and since that time the popularity of the breed has grown significantly. The Siberian Husky was not recognized by the American Kennel Club until 1930. Ironically, that is the same year in which the exportation of this breed was stopped by the Soviet government, who closed the borders of Siberia to external trade.
