Synopsis

Harvey Smithers is opening a new pet shop in Mayberry. Harvey is moving his business from the smaller town of Blue Hill. Mike asks Sam if he can have a dog, but Sam says he's not responsible enough. Mike visits the pet shop and befriends a mutt there. He asks Harvey if he could have a job there after school and on weekends. Harvey wants Mike to get Sam's permission. Mike talks to Aunt Bee and the two of them convince Sam to let Mike have the job. While at work, Mike tries to talk people into buying the mutt. Aunt Bee, Mike and Millie finally get Sam to agree to Mike having a dog. Mike brings the mutt home and names him Fritz. But, they soon learn that he is allergic to the dog. At the pet shop, Aunt Bee embellishes the dog's background and talks Howard into taking Fritz.
