There's a dog show in Greendale. Cassandra has a stunning entry. Margaux and Tiffany are helping her train and show it. Harvey has a nice little dog that he is entering as well. Sabrina decides to help Harvey so she can spend time with him, but also so she can beat Cassandra. But Cassandra's dog is so good looking and so talented that Harvey is almost ready to give up before the big day. Sabrina starts to wonder if something is wrong. She and Salem spy on Cassandra and discover that Cassandra's "dog" is really her evil rabbit Mephista, magically transformed. Sabrina then talks Salem into turning himself into a dog so they can beat Cassandra & Mephista, and the stage is set for a raucous, spell-filled, combative dog show. In the end, two witches' fake dogs take each other out - leaving Harvey's modest little dog to win the prize.
