My 3 year old gelding has a hoof ring (hoof is all smooth above this ring) and I want to make sure they are from diet change and not laminitis. He has never been overweight. I feed/work/check him daily and I've never noticed ANY sort of soreness on his hooves. He walks on rocks with no soreness either. There is absolutely no separation of the hoof wall from the sole. He has been on grass all summer then got put on Nutrena SafeChoice, but I have switched him to Nutrena SpecialCare. I am aware of the fact that his hooves need done and he has an appointment I will ask the farrier then, but I want (hopefully) peace of mind. The photos make it look more severe than it really is. You can hardly notice it unless you feel his hoof.
