Back to the foot rot....
Old school remedy. Put the animal up in a dry pen and keep them there for a week. Catch them every day and pour coal-oil on the infected area. This will cure it. Done it many times.
To prevent foot rot, you need more iodine. I kept salt blocks out, but they dont have enough iodine. I would get 50# sack of salt and mix extra iodine in it. Never had an animal with foot rot, again.
