Elmyra is chasing Buster and Babs again. They hide in a tree and are safe until their cover is blown by Furrball, who is being chased by a dog. The bunnies get away, and Elmyra returns home to her numerous pets. One of those pets is a brown dog that contains the Flea family. The dog starts scratching and Elmyra starts chasing him with flea killing spray. The Fleas try to get away from the spray by jumping on the dog that happens to chase Furrball to Elmyra's window. The youngest flea, Fliorello, bounces off the dog's nose and onto Furrball! The Fleas spend the rest of the episode trying to find their lost loved one. Menawhile, Furrball tries to get rid of Flio, but comes to like him. A big Bedbug comes along and tries to capture Flio. Furrball shows Buster and Babs the situation, and they try to help him. Buster, Babs, and Plucky (looking for fame in this episode) shrink to help out Flio. Furrball is chased by the dog with Flio's family on it to Elmyra's house. Elmyra gives Furrball a bath to get rid of the fleas, and ends up getting rid of the bed bug. Elmyra makes the mistake of suggesting that Furrball play with the DOG! Buster and Babs try to get him to confront the canine to get Flio's family back together. Furrball goes up to the dog and Flio's family quickly jump on Furrball to reunite with Flio. After scratching the dog on the nose, Furrball goes after him and shakes his hand, making a friend. The Flea family decided to live on Furrball.
