Starting a blog where people can share cute pet photos and stories, Janey receives a heartbreaking photo of an abandoned dog and enlists the aid of her friends to start a pet rescue club, in a story based on a true ASPCA rescue.
The kids in the Pet Rescue Club work together to help raise funds for a giant lovable dog named Millie who has been helping her owner train for a marathon but whose knees have been injured, requiring an operation her owner cannot afford.
When a tornado strikes, the Third Street Pet Shelter overflows with animals separated from their owners so Janey and her friends help take care of them.
