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! It's wintertime, and Little Dog is snug in his red doggy sweater. Big Dog wants a sweater, too! Their search may lead to some messy drawers, but who could mind when Big Dog looks so cute in his new duds? With simple text, graphic illustrations, and tongue-in-cheek humor, Dog Man creator Dav Pilkey taps into the joys of friendship through his tales of two lovable dog pals.
