I am not sure why your pet would be self-mutilating herself. Typically self mutilation cases occur with a recently docked tail, or cropped ear, or some body part that was recently operated on. Or they occur when a particular body part is painful to the pet. Unless there is some condition occurring under the skin that is irritating to your pet that has gone undetected, I see no reason for her to do this. Maybe this should be looked at by your vet to see if they can detect any abnormalities with the skin in this area. You can try placing a cone on her or a t-shirt to prevent her from mutilating herself until you can get her seen by your vet. If she is causing serious trauma to the nipple, then you may want to discuss surgical removal of the nipple entirely and/or oral medication for anxiety to see if you can curb this behavior. I will say this is quite a peculiar thing and is not seen commonly in pets. Hopefully you can get to the bottom of it before she does more damage to herself.
