Faith McNulty, a prolific children's book author, has written many science books for children. In this easy reader, she invites children to imagine a pooch-patrolled world! "If dogs ruled the world, they would keep people as pets." The dogs are taking us to the vet, giving us flea baths, and reading training books on how to teach us to sit and lie down. Children will love this silly story, with lively illustrations by Julie Durrell, about a topsy-turvy world.
