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.
She and her sibilings eventually got tired of cursing, as they realized it’s bad for them, and after all the scoldings from Queen Ava V. The other pets also decided they shouldn’t swear anymore, since they also realized they would get in trouble. She had been told by Princess Delilah that her mother should not tolerate any swearing.
