Sandy is the eldest of Angela and Mitch's puppies. She is a Retriever like her brother, Marcus. She enchants everyone with her winning smile and kindness toward others, but the other puppies also like her because she watches "Pet Park" and isn't afraid to swear. She bites her potty tongue in front of her parents and sister, though. Almost every day after school, Sandy and Mandy hang out at the Collar Parlor to chat with their friends.
