Between 1930 and 1955, Rin Tin Tin was cast in three different radio series, beginning April 5, 1930 with The Wonder Dog, in which the original
Rin Tin Tin performed some of the sound effects until his death in 1932. (Most of the dog noises were performed live on radio by a man named Bob Barker. This 15-minute program
was broadcast Saturdays on the Blue Network at 8:15 pm until March 1931 when it moved to Thursdays. Story lines were often highly unlikely, with Rin Tin Tin saving a group
of space-exploring scientists from giant Martians in one episode. In September 1930, the title changed from The Wonder Dog to Rin Tin Tin. Don Ameche and Junior McLain starred
in the series, which ended June 8, 1933. With Ken-L Ration as a sponsor, the series continued on CBS from October 5, 1933 until May 20, 1934, airing Sundays at 7:45 pm. The final
radio series was broadcast on Mutual from January 2, 1955 to December 25, 1955 a 30-minute program heard Sunday evenings. Sponsored by National Biscuit for Shredded Wheat and
Milk-Bone, the series featured Rin Tin Tin's adventures with the 101st Cavalry in the same manner as the concurrent TV show: The Adventures of Rin Tin Tin. The radio show also
starred Lee Aaker (born 1943) as Rusty, James Brown (1920–1992) as Lieutenant Ripley "Rip" Masters and Joe Sawyer (1906–1982) as Sergeant Biff O'Hara.
