I’ve recently noticed that my gelding will often have a patch of smegma or grease like gray material on the inner upper parts of his hind legs. He’s never has this before and I sometimes notice that the opening of his sheath seems to be a little dirty. However, he was sedated for the dentist the other day, so naturally I took advantage of that. His actual penis is very clean, and there was no bean. Inside of the sheath wasn’t bad either.
He is not itchy, swollen, nor does he appear to be in pain.
So, what causes this? How do I prevent it? I just scrape it off of the legs everyday, but I want to know why and how it even gets there. Any insight to this somewhat gross matter?
