''Lassie'' is a media franchise revolving around Lassie, a HeroicDog.

The franchise began with the 1943 film ''Lassie Come Home'' (based on a novel by Eric Knight), but really took off with the [[Series/{{Lassie}} long-running TV series]] ("[[CommonKnowledge What's that, Lassie? Timmy's fallen down a well?]]").

The original screen "Lassie" was a collie owned and trained by professional trainer Rudd Weatherwax, whose off-screen name was Pal. Pal starred in the 1943 film and six sequels; when the film series ended, Weatherwax acquired the Lassie trademark (in lieu of unpaid wages, according to one account), and the television series resulted. Pal retired partway through the two-decade run of the series, and was succeeded by a string of his descendants. (Yes, ''his''. All the dogs who played Lassie were actually male; male collies were thought to be more visually impressive, and less subject to seasonal shedding issues.)

!!Parts of the franchise with their own trope pages include:
* ''Film/LassieComeHome'' (1943 film)
* ''Film/ThePaintedHills'' (1951 film)
* ''Series/{{Lassie}}'' (the TV series)

!!Otherwise this franchise provides examples of:
* AnimalsLackAttributes: Lassie is a female dog (note the root of the name is ''Lass'' not ''Lad'') played by males with their belly hair coiffed very carefully to cover up the naughty bits.
* AmplifiedAnimalAptitude
* ABoyAndHisX: Boy and his dog. Different boy in each version, but always apparently the same dog.
* CrosscastRole
* HeroicDog[=/=]HeroicPetStory: One of best known examples.
* SmartAnimalAverageHuman: Creator/DaveBarry repeatedly mentions that the smartest character on Lassie is the dog, as the family is forever getting themselves stuck in deadly situations that Lassie needs to fetch the rest of the family to get out of. And even then, Lassie needs to bark for ten minutes before they finally get the message despite this happening every week. He believes Lassie has to do their income taxes as well.
* StageNames: Pal and his successors were all credited as "Lassie".
* TropeyComeHome: TropeNamer
!!References in other works:
* According to the director's commentary, ''WesternAnimation/WhereTheDeadGoToDie'' was originally conceptualised as a Lassie parody, and the first segment still, is, while the others have other stories. Suffice to say, this is a ''very'' dark BlackComedy example, since the Lassie analogue, the [[DarkIsEvil black]], [[RedEyesTakeWarning red eyed]] labrador named [[PunnyName Labby]], is a horrific {{Hellhound}} that convinces the child protagonists to murder his parents, rips his unborn sibling out of the mother's womb, and [[DepravedBisexual has sex with him and the mother's corpse]].
* Parodied with Laddie the Wonder Dog in the Discworld novel ''Discworld/MovingPictures''.
* ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'' has Billy addicted to a heroic Labrador also named Laddie; Billy often wonders aloud, "How many times can that kid fall down that well?" PS, he keeps watching the same video over and over.
* On ''The Jimmy Dean Show'' in the 1960s, Dean's co-star [[Franchise/TheMuppets Rowlf the Dog]] several times mentioned how much he admired Lassie, and Lassie made two guest appearances on the show. In the episode with Lassie's second guest appearance, Rowlf did a skit in which he acted out a Lassie-like scenario narrated by Dean, heroically fighting through hostile terrain, swimming across a raging river, and racing up the other bank to stop the criminals about to dynamite the bridge! ...at which point, Rowlf stopped the skit and complained that it would have been nice if somebody had mentioned the bridge ''before'' he swam across the raging river.
* Spoofed in the "Mindy and Buttons" segments of ''WesternAnimation/{{Animaniacs}}''. Its TitleSequence was a direct parody of the ''Series/{{Lassie}}'' opening.
* ''Series/ItsGarryShandlingsShow'' did a parody, involving a dog named [[LawyerFriendlyCameo Laffie]].
* ''Series/InLivingColor'' did a parody, involving a pit bull.
* ''WesternAnimation/MarthaSpeaks'' features the in-show TV program "Courageous Collie Carlos", of whom Martha is a major fan.
* Two in ''Series/WhoseLineIsItAnyway'': one suggestion for the everpopular ''Scenes From A Hat'' game was 'what Lassie is really trying to say', and later on an actual Lassie became the only animal guest on the show.
* "Sassy the Wonder Dog" is a series of radio ads from The Shelter Pet Project, where Timmy and Sassy often pause from helping one of Timmy's luckless friends out of the well in order to tell the listeners about adopting a dog from local animal shelters.
