Thanks Cinnys Whinny for the post. A friend told me that I could pour bleach in his hooves, but I was to scared to do it. I'm afraid it will burn them or something. As for the Koppertox, it looks like I will need to order it online. I guess I could use the bleach and water for a couple of days until the koppertox gets here.
To answer your question, his ear is hairy. I first noticed the soreness yesterday when I went to put his bridal on and he squealed, threw his head and backed up (he normally doesn't mind me touching his ears). He didn't want to let me get near it today either....putting on his halter was a real task. I don't think it will be better by tomorrow, which will make the third day (if not the fourth...I used a turnout rope sunday, so I wouldn't have noticed if something was wrong). I think tomorrow I will just go ahead and make him an appointment with the vet...just to be on the safe side.
