Zen - I'm at home, thus can't see videos (dang dial-up). Did this possibly start with some sort of bug bite? I had the same problem with Nala, my Aussie shepherd, and battled it for years I'm afraid to say. She constantly licked her left foreleg, and had three lick granulomas at the worst of it. Part of her anxiousness was that I was an unhappy camper.

What worked: I changed jobs. Started walking Nala every day for 20-30 minutes. Treated the wounds with antibiotic ointment that had some pain killer in it (OTC), covered with a sterile dressing, wrapped with kling gauze, then wrapped in kerlex (put those EMT skills to good use!). Fortunately Nala would leave the dressing alone. Change the dressing daily until the wound started healing. Yell "NO LICK" any time I heard the slurp slurp slurp.

You've got to redirect the pup's mind when they're doing the Obsessive-Compulsive thing, every time. Does pup get regular long walks? Not stroll around sniff every bush, but out there with a purpose, cover territory, brisk walk for 20-30 minutes every day? Maybe even twice daily?

Ever watch Ceasar Milan, the Dog Whisperer? I learned a lot watching his show.
