This should be on of the first books any dog owner reads. I was fortunate enough that I got it within two weeks of receiving my new AKC puppy. This will teach you about how your, and others behaviors affect and what they mean to a dog. It explains the instinctive pack mentality of dogs and the way they interpret dogs, animals and persons around them and their places in the pack. It explains how to understand the visual signs and actions of your dog so you will know what to do in the best way possible. My puppy peed in the house twice and pooped three times over a period of the first three weeks. I did not put his nose in it or yell at him. I reacted properly thanks to this book with my actions, care and love. My dog has not repeated this action indoors anywhere. My dog is cooperative in my training techniques and does what I coax him to do. The potty training alone makes the book worth the money but teaching is a breeze as well as knowing what he wants and the way he understands. I've had the precious baby for 10 weeks now. He is happy, intelligent, responsive and very loving. (A very cooperative relationship) It's great!
