What are your thoughts on the Cesar Millan's methods? I want to be a pack leader. I want a well behaved dog. I know when I adopt I may not get a dog that listens good, I'll hope for one of course, but I want to be prepared for the worst. One of Cesar methods is when you bring your adopted dog home for the first time, take a 20-30 minutes walk before going in the front door. That it initiates the "right state of mind".. And his walking methods. Are those good or bad methods?
