Zack and his dog, Rufus, are best friends. So when Zack goes to school, Rufus follows along. And once he's there, Rufus joins right in with painting, lunchtime, and even garden time — which makes for one messy pup when it's time to go home! In her digital illustrations, Alison Murray presents a very active tousle-haired tot and his scruffy pup, in colorful scenes filled with the things readers 4 to 6 love so much: toys, costumes, bikes, and piles of autumn leaves to jump in.
