Sailor (my horse) has an abscess. The farrier came out and trimmed him and the abscess popped. I have wrapped it the last two days with an epsom salt and iodine poultice, but he won't keep it on for more than 12 hours. He looked good yesterday so I thought he was all good so I didn't rewrap it. This morning I went out and he's limping again (it's all muddy and I don't have a stall). So I cleaned it really good with Dawn soap and just wrapped it just to keep it clean with no poultice. How long will it take to heal and what is your recommended treatment?
