I hope she grows out of it without any further treatment. It does sound terribly frustrating. She isn't spayed yet is she? And that won't help. I do wonder if there is something wrong with the formation of the vulva. Someone said, keep the puppy empty. I can't go with that. It is ok to take the water away in the evening to get a dry night, but you do not want a dehydrated puppy. She has to drink. In fact with problems like UTIs and diarrhea they need to drink. I agree that this is in no way her fault or yours. It is possible though that she will come out of this intact and be a great pet for you all. I hope that is the case.
