I started ignoring him. I walk away in the opposite direction and say 'leaving' or 'going home' and he stops. So far it's worked. However, I do like the clicker video. When he would not respond to clicker training. His ears would go back, he could turn his head and ignore. I may try it again. If it's distracting it might work.Have you tried any of the methods above?
We don't do a lot of brainwork. He can sit, lie down, but he doesn't often hold a stay. He listened more when he was a puppy. I will need to work more at his behavior.
