So I've never had to deal with rain rot, this year Scarlet got her first batch.....I'm assuming. Everyone at my barn was saying that's what it is. I noticed it because we went for a swim yesterday (her coat is pretty grown out this time of year) and I could feel scabs. They were wet and lifting so when I went to pull a few off, chunks of hair came with it. No flakes or dry dandruff or anything like that. So they suggested putting listerene on it.
I drew a quick picture of where it's at on her. What do you think?
Is there something I'm doing or not doing to prevent this? I don't always rinse her off after riding, but majority of the time I do. And then sweat scrape her.
