Rin Tin Tin in Rin Tin Tin (1954–1959)
Rin Tin Tin was a hugely popular dog who bridged the gap between the movies and television. He was a German Shepherd who appeared in at least 27 films in the 1920s and rose to fame on television in the 1950s.
The series followed Rusty and his dog, Rin Tin Tin, on their adventures in the Old West. He was sometimes called “The Dog Who Saved Hollywood,” as his films supposedly rescued the struggling Warner Bros. studio from bankruptcy.
