Bella instantly falls in love with her scruffy puppy Sid when she sees him at the animal shelter. She gets her family to agree that he's the perfect pet for them and she cannot wait to bring him home! But one person is not too impressed with Sid - Bella's friend Megan, who is getting her own pedigree pup. Megan is pretty snooty about Bella's beloved mongrel pet, and she begins to wonder if she's that good a friend after all. Bella decides to enter Sid into a dog show, so she can prove for once and for all that all dogs are brilliant, no matter where they come from.
