Balto, the siberian husky sled dog who helped save hundreds of lives in Nome, Alaska, appeared on KGO on May 19, 1925.   The famous dog led his team on the final leg of the 1925 serum run to Nome, in which diphtheria antitoxin was transported from Anchorage to Nenana, Alaska, by train and then to Nome by dog sled to combat an outbreak of the disease.    On February 2, 1925, the Norwegian Gunnar Kaasen drove his team, led by Balto, into Nome.   At Nome, everybody wanted to thank Kaasen at first, but he suggested giving fame to Balto as well.  The KGO press report said that Balto was "very tame, likes boys, and isn't afraid to 'bow wow' for radio listeners.

Balto was on a tour of the country that ended in New York in December, where a statue of Balto, sculpted by Frederick Roth, was unveiled.
