Mystery of the day - what is this, how do we think it happened, and what to do about it? I noticed my gelding's sheath looked swollen, and upon closer inspection, he has the appearance of growing 2 extra fuzzy peaches in the wrong place. I only noticed it today, and it doesn't appear to be swollen inside, just what you can see. He doesn't seem to be in any pain, but I'm more concerned that swelling in the area might impede his ability to pee. Ideas?
