First Book of Puppies

Part of the Baby Einstein series, this cheery lap book repeatedly poses the question, "What do puppies love?" The answers appear in a mix of photographs and cartoon scenes that display puppies running, playing, eating, or sleeping. Each spread includes one or more windows, embedded within the page, that can be slid up. When readers do so, cartoon portraits of puppies are replaced with photographic ones engaged in the same activities. A toddler-pleasing combination of realistic and make-believe. All ages. (Aug.)
