Relaxation walking

I did my first session on my own today of the relaxation walk where we have to walk in circles at a slow pace round an obstacle. I set up two chairs in the back yard and walked round, sometimes changing direction. We walked for 20 mins at a slow and steady pace. I had expected him to react to this as he had at Thursday's training session. But he didn't and we plodded round with no ground sniffing, no lead biting etc. I'm supposed to do this 3 times a week as a minimum, but everyday if I can.

We finished off with a little round of his known cues like: touch, sit, down, go round etc.

I need to think of 2 new behaviours to teach him that I can add into this.
