“A delightfully fun read that will leave you in stitches!”—Caldecott Medalist Dan Santat

When a bouncy, barky dog and an evil genius guinea pig move into the same house, the laughs are nonstop! Wedgie is so excited, he can’t stop barking. He LOVES having new siblings and friends to protect. He LOVES guinea pigs like Gizmo! He also LOVES treats!

But Gizmo does not want to share his loyal human servant with a rump-sniffing beast! He does not want to live in a pink Barbie Playhouse. Or to be kissed and hugged by the girl human. Gizmo is an evil genius. He wants to take over the world and make all humans feel his wrath. But first he must destroy his archenemy, Wedgie, once and for all!
