Balto (1919 – March 14, 1933) was a Siberian Husky and sled dog belonging to musher and breeder Leonhard Seppala. He achieved fame when he led a team of sleds dogs on the final leg of the 1925 serum run to Nome, in which diphtheria antitoxin was transported from Anchorage, Alaska, to Nenana, Alaska, by train and then to Nome by dog sled to combat an outbreak of the disease.
