Frank is Greg's, Rodrick's, and Manny's father. He is the husband of Susan Heffley (Greg's mom). He sent Greg to some camp thing due to Greg being 'wimpy' (as shown in the title).In Dog Days, it says that he used to have a dog when he was a kid, but his dad (Greg's Grandpa) ran over it while backing his car up. So frank gets Greg a dog named Sweetie (Susan named it). Greg grew tired of the dog, so Frank gave it to Greg's Grandma.
