Since Charlie and Itchy don't get along, and the former doesn't want the latter going with him on another mission, Annabelle takes Itchy's place as they go on a mission to teach a child exterminator named Teddy not to treat dogs as he treats them. Eventually, after Charlie uses Annabelle's miracle to turn Teddy into a dog and the latter learns about what it's like to be a dog, the mission gets them sent to the pound. Will Charlie admit he needs Itchy?
