Practicing turning right and left

We’re taking a few minutes at a quiet train station to practice working on left and right turns. I am purposefully, avoiding the edge of the platform where the trains pull in because in general, I want to keep my dog away from that space unless I am working with him to get on a train. When I am practicing like this, he is often looking up at me the entire time like he is in this video but when we are out walking in public for a relaxing walk, he only tunes in like that when I am asking him to or we’re navigating a complicated situation. This dog has been trained using positive reinforcement, which is also known as clicker training. He is currently four years old in this video.
