Does Rusty over-reach a lot? Just curious, beacuse we had a TB that used to pull shoes left and right, wether he was playing or working. Got to the point where he wore bell boots almost all the time, just to protect him from himself.
The only time he has ever overreached is when he is running a bucking out in the pasture. He has never done it when riding. I think he just get very exuberant, he really slings himself around when playing.

I used to have a horse that over reached and would loosen the front shoes. I believe this is called forging. Anyway, a good farrier can fix this easy. Found a link for you that will give you a better explanation than I can.
