I purchased this book before we got our Yorkie so I could study up on what all I needed to look for while searching for my dog and what to watch out for it. It helped in having what I needed in going to pick him up and taking care of him thereafter and when we thought he may not be feeling well. It covers a lot of different information, and even some tidbit information too. I also like the way the book is divided so that you don't have to read up from front to back and you can just look up exactly what you need to. This was a must have and we are glad we got it before and plan to keep refering to it. Thanks Overstock!
