That’s not my point. I see what you’re saying. Street dogs can be very scary. If you met a dog trained by me, she/he would sit where I placed her and not move. Until I called a heal. she would instantly move to my left leg and sit, unless I was walking. Then she would follow along rubbing her/his right shoulder against my left leg. Making sure she is where she is supposed to be. Would do this all with hand signals. Dogs are very smart, easy to train, and very happy to please.
