Many people spend a good amount of money to have their dog trained so that they will have a dog that obeys them and doesn’t drive them nuts. They have trainers over to their house and spend time every day practicing with their dog walking, sitting, waiting, etc. They do all these “dog training” things and their dog still doesn’t listen to them and is always bugging them to play, let them out, etc.
The problem is that they missed a very simple point in telling their dog “Who is the Boss?”. They went through the motions of trying to establish leadership, but they missed the bull’s eye. They didn’t maintain the concept of “Who’s idea is it” to establish the leader and the follower.
