The episode was written by series co-founders Trey Parker and Matt Stone, and directed by Parker. In this episode, Stan's dog, Sparky, is revealed to be gay after humping a rival male dog. Under peer pressure, Stan tries to make him more masculine, and as a result, Sparky runs away and ends up at Big Gay Al's Big Gay Animal Sanctuary. Stan comes to understand homosexuality and tries to make everyone in South Park accept it.

"Big Gay Al's Big Gay Boat Ride" addressed open homosexuality in a way that was uncommon for television at the time, which created some anxiety among executives at Comedy Central. The network initially objected to offensive remarks made by sports commentators in the episode, but the comments were kept in at the insistence of Parker and Stone. Stan, Kyle, Cartman and Kenny's designs were changed slightly in this episode and these designs would remain for the rest of the series. George Clooney made a guest appearance as Sparky, a small role with no dialog except for dog barks. The episode also marked the first appearance of Big Gay Al.

The episode received generally positive reviews for its portrayal of homosexuality. Creators Stone and Parker considered it their favorite episode of the first season, noting that it helped elevate the credibility and relevance of South Park during its early days. It was nominated for both an Emmy Award for Outstanding Animated Program and a GLAAD Award for Outstanding Individual Episode, and was the episode submitted when South Park won a CableACE Award for Outstanding Animated Series.
