How do you guys treat rain rot? I'm currently using a diluted betadine and spray it on him after I take the scabs off. Also any tips for preventing rain rot?

M-T-G and medicated shampoo together.
My mare had rain rot and I started using medicated shampoo that fights fungus and rain rot. WORKS! Also helps thin mane and tail.
To prevent it you could take him inside when it rains if you can or get a waterproof sheet to put on when it rains. Hope this helps!
Use Dover shampoo. Works wonders
