Chainsaw is Pete's dog in Goof Troop. A running gag involves Chainsaw tormenting Waffles, Goofy and Max's cat, and she usually ends up chasing him. Frank Welker did her vocal effects.
- Chainsaw is absent from both A Goofy Movie and An Extremely Goofy Movie. Though it is possible that she passed away due to the movies taking place three and six years, respectively, after the events of the series, the most likely reason for her absence is that she (as well as Waffles) simply didn't factor into the father-son story that the movie wanted to focus on between Goofy and Max, at least not in any meaningful enough way to warrant an appearance in the movie for Chainsaw.
- In earlier model sheets, Chainsaw was to be of a breed of a Bulldog or Great Dane.
