Query: This is an outstanding book for the first time dog buyer!

I have always wanted a dog and when a good friend of mine said that he would purchase one for me I was ecstatic. Not knowing what kind of dog I wanted, though, I decided to get online and get some information. Picking this book was the best decision I could have possibly made. I knew I wanted a small dog but didn't realize the different breeds and some really important characteristics that dogs have. This book was excellent in telling me the dogs' habits, what kinds of environments they need to be in, their health problems, and even what dogs not to pick out of the litter. It even gives you tips on how to recognize a dog that isn't a true breed; and with the detailed pictures that are contained within I am very confident that I will pick a perfect dog for me. This book is a must have for anyone thinking to buy a dog for the first time and wants to feel comfortable with their final decision.
