My opinion is that you can take something from ervery book and video out there. I also believe that you cannot follow every bit of advice in any of them for your dog. I have read and watched many training aids and have come up with this hypothosis. My reasoning is that when I tried to follow Wolters exclusively, I got discouraged and so did " pup" . I found that taking what worked for my puppy worked best for me. Love is the most important thing at an early age. Good luck.
