Today when I caught Ace to take him back to the stall, I put a lead rope on him. I didn't want to do this in the stall the first time in case he fought. Out in the arena, I could handle him without worrying about him crashing into a wall. He accepted it well and only pulled back a bit but I stayed with him. Since he already knows the routine, he started trotting back towards the gate. I let him stay a step ahead of me, and kept my hand on his rump encouraging him to walk alongside while I guided with the rope. He got back to the stall without even realising he had just gotten his first leading lesson.
