Query: A Godsend!

This book is a Godsend for folks trying to decide which is the right breed of dog for them. Concise yet complete, and very readable. You sit down intending to glance through your new book, and end up reading it cover-to-cover (often laughing out loud). You now have a short list of possible breeds, and you know just what to do next, to find your dog. Great book for dog-hunters!
