Here's a breakdown:
* The Original Lassie: The first Lassie, who starred in the original 1943 film "Lassie Come Home," was a female Rough Collie named Pal. Pal was a champion show dog, and her success in the film led to a long and successful career in Hollywood.
* Other Lassies: Pal was succeeded by a series of other Collies who played Lassie in various films, television series, and other media. These include:
* "Lassie" (1949-1958): This series used several Collies, including "Lad" and "Shep".
* "Lassie" (1958-1973): This series featured "Lassie" (the dog's official name), who was bred from Pal and appeared in the majority of the episodes.
* "Lassie" (1994-1997): This series featured a Collie named "Lassie".
* Other media: There have been other films and television series with Collies playing Lassie.
* The Difficulty of Counting: The number of Collies who have played Lassie can be tricky to determine definitively. Some sources count individual Collies who appeared in multiple episodes of the same series, while others count different dogs who played Lassie in different productions.
Ultimately, the number of dogs who have played Lassie is somewhere between 7 and 14, depending on how you define "Lassie" and "played."
