"Titus wants to be a good dog in his new home on the farm, but he can't figure out what that means; when he tries to board the school bus with the children, chase mice or lay eggs, or help the farmers plow and milk, all he hears is "No, no, dogs don't..." What DO dogs do? Titus learns at last that night, when he spots a fox sneaking up to the henhouse. Halpern's neat, brightly lit cloth-and-paper collages make perfect accompaniments to this simply told story; the widely spaced farm buildings are set on a grassy hill dotted with flowers, and Titus, golden, flop-eared, the picture of puppylike confusion, draws the eye even when the point of view is pulled back. Treat fans of Eric Hill's Spot books to a story with a real plot."
