It could be a penis ring, or just over grooming. My bucks tend to "Overgroom" down there and sometimes they cause themselves to bleed. They usually do this after they eat, and from what I've been told it's normal. However it could be a urinary tract infection or just a nick.


Chinchillas also get penis rings. I am not sure how to go about treating it, but the hair would have to be removed. Let us know how he is doing.
