I love this book. Love it. It's short, simple and funny. Kid wants a dog - kid finds a dog and keeps it secret.
I work with reluctant readers, so something accessible, entertaining and short enough to get through in a couple of sessions is a great find, but I also liked it for what it is - just a great little story.
The illustrations are deceptively simple, just stick figures and line work, but they work. What's more, it gives another great message to kids because they are easy enough to copy, showing that you don't need to be a brilliant artist to tell a fantastic story.
