@Chunksmama Actually I have asked about 6 different (oh, wait, 7) vets at three different practices about the chin bumps. All said acne. None of them could give me any more info on how to prevent them. Their suggestions were: animax (panalog), chlorhexadine wipes, stainless bowls, smooth bedding (such as sheets), remove crate pan or clean daily, or try stridex pads or the lowest % of benzoil peroxide cream you can find at the drug store. I am actually not so sure that food is related. Gator's are completely gone now (knock on wood) and then Gypsy's flared back up and had to be treated with antibiotics and are almost gone.
