Query: Very Helpful Book!!!

I love this book. After adopting 2 baby Great Pyreness puppies, this book helped me understand them in a way I would have never known. They are beautiful dogs that have lots of love for there owners, however they like to have a lot of land to roam, and have a big barking issue. This book taught why they bark so much, it is because they are WATCH dogs, and they feel the need to bark in order to protect there heard/Owners. Great book!
