Dr. Gerbil is a minor villain in Courage the Cowardly Dog. He appears in the episode "Human Habitrail".
In the episode, he poses as a vaccuum cleaning doctor, and uses a vaccuum to suck up Muriel and Eustace. He then tells Courage that he'd been freed of his torment. He then puts them through all kinds of tests as an act of vengeance on humans for their mistreatment of animals. He later chases Courage in a waterboat, and falls off a waterfall to his apparent doom, later on it is revealed he survived.
- Despite being one of the more comical villains in the show (horribly experimenting on humans aside), the scene where he chases Courage near the end of his eponymous episode can be considered very dramatic due to the creepy music in the background that is played during his chase and him nearly drowning after going over the waterfall.
- The song played in his lair 'It's the Gerbil's World' can be considered a jab at the widely-disliked song 'It's a Small World After All' that is played at Disney World as Courage is seen barely keeping himself together when listening to the song. The ride that Courage takes in Dr. Gebril's lair is even a parody of the ride at Disney World.
