Hi. Walkamile, they do sound familiar. I wasn't necessarily convinced it was rain rot but my boarder who has much more experience with horse health issues than I do, decided that's what it probably was. I'll try to get a picture when it stops raining, Countrygal--
He has had the occasional mystery crud now and then over the years, ringworm once a long time ago. I pulled out the Betadine last night. He's mostly old-style Morgan and grows a coat like a buffalo.Walkamile, I'd love to hear what your vet says, and it is an interesting similarity, I'm in Vermont. The ticks have been really active lately but I'm not sure that's what this is, dunno. Betadine to the rescue!
