Patricia McConnell, PhD. has written some of the best training books for you to read and incorporate with the training of your dog. Leader of the Pack is a 16 page pamphlet packed with years of knowledge of how to get the respect your dog wants to give you. Ms. McConnell's books are easy to read and in simple to understand directions. I give these books to all of my puppy people, The Bible's of the Dog Training World to me! Never own a puppy with out them!
