MTG smells like bacon or BBQ, hate the smell, but since I moved my horse, and no longer use MTG (only cause I don't have my own bottle yet), her rain rot has definitely gotten worse. I was a bit skeptical about using MTG because I've known several people who used it for itchy skin, not rain rot or anything, and it actually made their horses itchier, but after moving her, and seeing it get bad again, I do think that the MTG did help. I also just applied it everyday. Some days I would give her a bath cause she needed one, but then I started applying it again as soon as she was dry. What I like to do, is bathe her, soak her butt a bit, and then either take my fingers, or a flea comb, and gently remove as much of the scabs as I can, before reapplying medicine, because the scabs trap in the fungus, and keeps it from going away as well. Hopefully soon I can go and get a bottle of MTG, and start back up with it. Just make sure that you don't get it on your clothes, because the smell doesn't come out. Or wear clothes that you don't mind smelling like MTG.
