Whenever I want to come back down to a walk after trotting, but mainly cantering, my horse wants to speed up again. But it's funny- if I give him a completely loose rein, he'll stretch his neck down and relax and walk, though he will try to speed up a little, though not as much as he would when I keep contact on him. Why does he do this? It gets tiring after a while having him keep trying to speed up. Like I said, if I give him a loose rein he'll settle down much faster, but I can't always do this. I want him to walk while still on contact. It's like he anticipates that I'm going to ask him to do something again, but I just want him to walk!
