Balto was an Alaskan husky and sled dog bred by musher and breeder Leonhard Seppala. Balto achieved fame when he was reported to have led a team of sled dogs driven by Gunnar Kaasen on the final leg of the 1925 serum run to Nome. From Wikipedia
The unit has bolstered its detection capacity by inducting Zory, Balto and Kali following the retirement of two decorated dogs.
