Sooner or later the medical profession at large will catch on. Dave Groomer has more knowledge on this subject than most. He works with dogs and has many of his own, and it wouldn't surprise me to find out that all of his pets get cannabinoid therapies. It can make all the difference. For sure I'd try a topical. That's probably a little tender for the dog. The cream would eliminate much, if not all of the discomfort.
It really feels like magic Lady G. You hurt, you rub the cream in, and before you've stopped massaging it in the pain vanishes, or at least drastically diminishes. Get some and make a cream for yourself. Arctic Bowl's beloved swears by hers.
