Lassie, who was supposed to be female, was played by a number of male dogs, beginning with “Pal.” Benji was played by himself. Rin Tin Tin was played by himself, too, but after his death in 1932 was portrayed by Rin Tin Tin Jr., Rin Tin Tin III and Rin Tin IV. Today Rin Tin Tin XII is still making public appearances.
