I watched his show this past weekend, just to see what all the fuss was about. I did enjoy it and I'd watch it again, but I just have to say--He's no dog whisperer. He is a marketing genius and an extremely savvy business man. His training techniques all seemed pretty basic to me--a tired dog is a good dog and dogs need leadership. Those are the two principles I manage my pack on!
I have a friend who is a dog whisperer. It's astonishing to watch. Even dogs who have never met Will before respond immediately to him!
