Lassie: The Collie Who Saved People On TV For 60 Years
Of all the TV and movie dogs, the collie named Lassie is top dog in every measurable way. The Lassie TV series ran for 19 seasons, tallying 591 episodes. The TV show (in some form) has been revived on three separate occasions. There have been 10 Lassie movies, and there was even a Lassie Playstation video game. And at least 13 different dogs have portrayed Lassie on screen. Rin Tin Tin had an impressive run before Lassie, and latter-day would-be Lassies like Benji, Beethoven, and Hooch have all seen their moments in the sun, but Lassie is the institution.
Lassie was last seen on TV in the 2015-16 animated series Lassie, which lasted for 26 episodes.
