I used to keep my horse's back hooves unshod, and when riding on our rocky, steep, nasty trails, I would put hoof boots on him. He would beat the heck out of the fronts of them, breaking latches. Last time it happened, I decided to shoe him on the back. After another ride on some nasty terrain, I found that he hits the front of his back hooves, and actually marked them and dug out a little chunk on one of them. Is there such a thing as hind bell boots? I tried googling, and didn't find anything, and I don't think front boots would work since they're higher in the front, where he needs the protection. Thanks!
The rubber kind that are the same length all the way around will work-- the no-turn ones won't help with your issue. You might also talk to your farrier first. Sometimes they can adjust the shoeing job to help/ cure this.
