My yearling broke out in a horrible case of rain rot. Nothing was clearing it up, I used Cowboy Magic spray/shampoo for it, Eqyss medicated shampoos, and sprays, Iodine, and dish soap, anything and everything I could find, and it was honestly just getting worse!
Cherie, a member on this forum told me about Vitamin A, and how that would probably help. I was kind of biased to be honest, because he is perfectly healthy. But I ended up giving in and buying some, literally 3-4 days after I gave him some Vit A, the scabs were falling off by themselves! He now thinks it itches for me to rub him in those areas, where before he was flinching with pain! I highly suggest small amounts of Vit A! It really did wonders for my little guy! Good Luck!
