Ok now his feet were not long but walls were soft from all the wet, he has no smell, nothing coming out of the area. In fact after I cut this back and got him on concrete it was dry. The ground here has frozen, then thawed, horse hoof makes walking on the ground a challenge. It looks like this inside wall got tore off then packed with mud. Tonight it had slight mud in there but was dry after I cleaned it out. Is there anything I can do or put on this to help it heal. He is not limping or lame in anyway.
