From New York Times best-selling author Dav Pilkey, creator of Captain Underpants and Dog Man, comes a charming board book series for toddlers about two canine companions who can't resist mischief! When canine companions Big Dog and Little Dog play a little too roughly with the couch cushions, they learn that best friends have to be great at sharing--in this case, sharing the blame! With simple text, graphic illustrations, and tongue-in-cheek humor, Dog Man creator Dav Pilkey taps into the joys of childhood friendships through his tales of two lovable dog pals.
