I recently had a problem where my horse had these huge bug bites so I used some iodine for a week to treat them and then , because the iodine says not to use longer then that, I used bag balm. The bites have gone away but now his whole chest is shedding so bad it's almost bald. The only other thing I put on him was fly spray. I was wondering if anyone else has ever had this problem or knows what caused it and how to fix it. Please.
