I love this command! I've branched it off into two separate commands, touch (with a ruler) and nose boop (with a hand or object). Enzo loves to nose boop. To teach him, I just held the end of the ruler (for touch) and my hand (for nose boop) and clicked and treated when he booped it. I want to try to teach Enzo to touch or ring different things (for example, a bell for outside, a different one for play, etc) if he wants something.
