A few days ago I was out petting my sisters horse and I noticed that she had a rough patch on her shoulder... So I naturally looked at it and ran my hand back across it... I pressed on it and she acted like it was tender. I went back today and looked, and it looked as though whatever it is that's on her had spread...Whatever it is that's on her feels like little scabs of some sort.. just in a patch.....
So, I started looking around on the internet to see if I could come across anything......... I came across rain rot... and it said that it happens primarily in hot humid locations.. and it's the middle of winter here.... So, I am not thinking that it's that?
I was thinking that it could be a fungus of some sort.. but I really don't know.
Does anyone have any suggestions as to what it might be?
