Equine Melody, just a thought, but are you sure your horse isn’t stretching his back? That reaching for the ground thing is a goal for most of us, and it could be that you’re fighting a good thing. Of course, if there are weeds involved and you’re sure he’s just rooting, that’s different. My oldest mount went through a period of excessive stretching (mine’s a sand arena, so no weeds to root for), and I finally figured out that he’d put on enough weight to make his saddle a little pinchy. I changed saddles for one with a wider gullet, and he only stretches now when we’re warming up.
