If it's just a little licking I would just keep an eye on him but if it becomes excessive it could be an allergy or maybe even a form of OCD. This kind of behavior can evolve into a big problem. They can start chewing, develop hot spots loose hair etc. See a vet if you are concerned. Also make sure you are feeding a good quality kibble and no people fool so you can try and figure out if it's a food allergy. I have heard wonderful things about a product called missing link, it's a supplement that you sprinkle on their food. You can purchase on line, at petsmart, petco, etc. I have heard many testimonials from many people that have had dogs with skin or allergy problems. The see major changes in their pets. It's suppose to be great for them and improves coat quality. I started mine on it about a week ago...not for skin problems...just the health benefits. Visit the website of the company and read some testimonials. I first heard about from Dogomania. It may be worth a try. Also...Bitter Apple can be applied directly to the dog to discourage licking, fur biting. etc. That may seem harsh but to prevent a very disfiguring habit from forming sometimes may take some extreme measure. It says directly on the bottle that it can be used for this. I have no idea how much your dog is doing this but I have seen photos of some pets that get themselves into a bad situation from this type problem. I would try and nip it in the bud. Good luck.
