You've given me a few ideas for working with Kita. She is okay with moderate traffic, but often startles and moves a foot or so away when a large truck or other noisy vehicle goes by us. I worked with Zoomer on both left and right, just because there were times that it was handier to have her on my right. Teaching Kita that too. I usually have my dogs on my left, because that is where we started when I was first told how to train, and it did work okay for us. Jo
