Ok so i have been having a "friend" feed, ride, and groom one of my horses for me. I usually check on him once a week (just an eyeball) to make sure he's ok. We'll she left to go out of town for the holidays today so i went out to feed him and groom him. I pulled his blanket off and ran my hand over his back and discovered he's covered in rain rot. Poor guy obviously has not been getting groomed like he's supposed to. Anyways i have a tiny bit of muck-itch left which i sprayed on him today, however when thats gone i'm up a creek b/c i dont have the money to buy him more. I'd rather not dip into my emergency fund to pay for a bottle of fungus spray if i dont have to. Does anyone have any easy, low cost, home remedies for getting rid of rain rot?
