I'm not very sure if its rain rot but I think it is. It's hard to explain what it looks like but the soonest I can get some pictures is tomorrow or the day after.
If you don't mind i'd like to see some of your pictures of horses you've had/have that has had/has rain rot and i'd like to know a good treatment to. I lite to have a supplement that I can put on not one that goes into there food.
If you can help thanks. He's had whatever it is for a little over a month maybe more. It's not bad that's why I never worried about it but it's making me very curious what it is and since where about to start working him under saddle i'd like him to be healthy.
