List of Lassie (1954 TV series) episodes

[1] The series continued to air in rerun syndication (both on broadcast TV and cable), off and on, for another 50 years.

At the opening of the 11th season, a job transfer sees the Martins moving to Australia and having to leave Lassie behind in the United States.

After a brief stay with family friend Cully Wilson, Lassie joins Corey Stuart (Robert Bray), a ranger with the United States Forestry Service.

Early in the 15th season, Stuart is badly injured in a forest fire, but Lassie remains with the forest service in the care of rangers Scott Turner (Jed Allan) and Bob Erickson (Jack De Mave).

Season 17 would be the series' last on CBS, which canceled the series in 1971 as part of the "rural purge" (a move to replace what was seen as rural/family based shows with what was deemed to be more urban centered, "socially relevant" programming).
