Book excerpt: When the going gets tough, Dog . . . takes a nap Dog can Sit. He can Stay. He can even Dance. But when he's in charge, can he keep the cats in line? All one, two, three, four, five of them? Illustrated by Caldecott winner, Dan Santat, and packed full of slapstick silliness and utterly earnest charm, Dog will quickly wiggle his way into preschoolers' hearts.
