Fan Question: I don’t think I’ve seen Sparky since he ran away in season one. Did he run away for good?
Answer: The toughest dog on the mountain? Hell no!
Sparky was front and center in “Proper Condom Use” when Stan tried to milk him in front of his parents… and their friends. “Come on Sparky! Red rocket! Red rocket!”
When Butters took a ninja star to the eye in “Good Times With Weapons” the boys had to dress up Butters as a dog to get him to a veterinarian (and avoid a grounding). Sparky unwillingly gave up his fur to complete the disguise.
He’s also occasionally spotted in Stan’s house, like this scene from “Woodland Critter Christmas”.
Most recently, Sparky played a huge role in “South Park: The Stick Of Truth” where he (and his red rocket) are needed to advance through different parts of the game.
