If anyone could help me identify this problem I would be greatly appreciative. My 10 month old Black Lab has a clear, odorless vaginal discharge. She is eating, sleeping, and playing normally and has no signs of discomfort. She is however licking the vaginal area with some intensity mostly at night. She has been spayed. I am not sure if this is a serious problem or not and if it requires veterinary attention. If you have any information on the subject, please let me know.
