Hi Marilyn,.Dogs can indeed develop behavior considered to be OCD. Often in a case such as you are describing, the dog develops skin infection, hair loss and even sores in the area, so stopping the behavior before it gets too much worse would be recommended. Often this licking behavior starts due to an allergy condition or thyroid issue. Those are things you would want to ask your vet to check for. .A dog that licks their paws often frequently develops a yeast infection causing hair loss and inflamed skin. If it progresses to that point, you would want to soak the feet in epson salt water and apply neosporin or miconazole cream 3 times a day until it clears up. I personally would think about having her Vet check for a thyroid condition if it becomes worse or she develops any aggression issues or hair loss on other parts of her body..Frequently a dog will start licking for a specific reason such as a cut or insect bite and continue long after the original cause is gone. This can develop into Acral lick dermatitis or lick granuloma. You can read about this here:

At this point, it doesn't seem he is doing too much damage to himself, but I would try to stop the behavior if you can. Baby socks might help stop him from using them to comfort himself. A dap collar that uses pheromones to calm dogs might also help stop the behavior since it mimics the pheromones produced by a nursing mom to calm her pups. You can purchase these at the pet store, online or at the vet office.
