What should I do to help correct Moe's hoof? The inter wall is cracked and pulling away from the pad. He gets a pebble stuck in it sometimes. It has been like this for several weeks. I keep trimming it, plus using a sure form after but, the crack doesn't seem to be getting any better. Today I trimmed again and put some "Tuff Stuff" all around the hoof wall. Does anyone have a suggestion? Is there something else I should do?
