Seems he would easily turn out to be a good roo. If he should come at you, you come at him looking him straight in the eye, and keep making him back up and back up....every time. Do not back up. Just keep stalking him. Do this each time and you will be telling him that you are the alpha roo- in roo-speak.
I will try that,thanks. Since feeding treats he hasn't charged us. I don't walk around him, I make him move when I'm walking.
