Balto was never an outcast street dog as shown by the film, but was instead born in a kennel owned by the famous musher Leonhard Seppala, where he was trained until deemed fit for pulling a sled as the lead dog. Seppala was also the owner of Togo (1913–1929), whom he personally used to lead his dog team during the relay. Balto was used by one of Seppala's workers, Gunnar Kaasen.[4][5][7]
