I've had my horse for ~a year. His feet were not good when I got him and then they went straight down hill. I changed barns and farriers and he's made such a difference. I have him on a supplement for his feet--called Equitin, 100mg of biotin per serving and I forget the levels of the other things. I have been using rainmaker, the farrier has him in corrective type shoes (he was so out of balance and flaring was out of control and one hoof cracked all the way through the coronary band). New growth is much better and stronger (coat is wonderful, too) but his feet are so dry it is a disaster. The farrier keeps telling me he can't do anything else until we can get the dryness under control. He has come back from EPM in his early life, he has EPSM and I feed accordingly, and he has supplements and electrolytes, and trace mineral salts, etc...What can I do? His feet are just crumbling Can anyone recommend something that will help? Hay was tested, it is good quality and forage is good...I just don't know what else to do and even my farrier is frustrated....his feet are embarrassing and though he doesn't act as if they bother him, I can't imagine they feel good!
