I read this for a school-age storytime. It's an epistolary story told completely through letters, primarily from Arfy the dog who is searching for a new owner. There's a great back-and-forth between Arfy and each household who denies him until ultimately he receives a happy ending with an owner. It's great to demonstrate the different ways letters can look and how mail works. The kids really liked this book, and they used clues from the pictures to guess whether or not the house to which Arfy was writing would reply yes or no.
