It might be a reaction to insect bites. Try "Cough Free", an equine antihistamine.

Just guessing here and it's very unusual but I think horses can get fleas from mice and rats if there are a lot of them and your horse is in a barn or stall situation. Don Huston

Hi all,
was wondering what insect bites the horses under the tail and also
around the anus area this time of year?(march-april)
the rain has not stopped and am wondering what bug is doing this to my
poor gelding! He wants to rub his tail off- he even backs
up to me wanting me to scratch his butt! the midline under his belly is
already eaten-up. I have tried the clear swat but doesn't seem
to help.Thanks, Tara
