Challenge of the Yukon (Sergeant Preston)

"On King! On, you Huskies!" To the strains of the Donna Diana Overture, this Mountie trekked across Canada, much like the Lone Ranger trekked across the American Southwest. No coincidence -- both shows were created by George Trendle of WXYZ Detroit, both to the same successful formula -- the strong, law-abiding hero; the animal sidekick; the exotic location; public-domain classical music. Sergeant Preston merely lacked a Tonto to make the parallels complete.
