Mad Cow is a bull who's an inmate at Petropolis Prison. He was first seen as prisoner who escaped in Snap Dad. However, in Dog Dish, he was shown to be in jail again. It's possible that he was captured off-screen. He almost escaped with the help from D.O.O.M., but was stopped by Dudley Puppy and Kitty Katswell. He was also briefly seen behind bars in Doom and Gloom.
