Also, have your dog checked for any other medical problems. It is a very unusual presentation of medical disorders, but good to have full checkup and blood-work screen done if you can.

Great idea! Any time a behavior changes and something weird shows up is a good time for a med check. Licking might be OCD but also might have started because of a medical issue. How long has the licking been going on? Any changes in diet, exercise, environment?
