Little Dog has a sweater, but what about Big Dog? After a quick search in the bedroom (and making a bit of a mess), Big Dog finds the perfect one. But how will he put it on? Good thing he has Little Dog to help!

With deceptively simple text, graphic illustrations, and tongue-in-cheek humor, Captain Underpants creator Dav Pilkey brings the joys of childhood friendships to life in his tales of two lovable dog pals. This Green Light Reader will help young children build basic reading skills while also tickling their funny bones. Parents and kids looking for skill-building activities will find a bonus activity section at the back of the book that includes a word search, story-sequencing activity, a maze, and more!
