My horse, Splash has a round bare spot on his shoulder. He has had it for over a year. Hasnt gotten any bigger or smaller... But there are alot of little bumps on it.
Well then I put iodine on it and everywhere that the iodine went it swelled out a bit.. so I wondered if he had an allergic reaction to the iodine, so I put a little bit on his other shoulder just on the fur and it swelled up to.
So here are some pictures. The first & second picture is before I put iodine on it and then the other one is about an hour after I put iodine on it.
What do you think the round spot is?
