Shelly - If you aren't using boots get some right away. The difference might be night and day. I personally like Easy Care Clouds, but there are several others (I think I've tried half of them!!) Use whatever makes him comfortable. I currently use a different pad in my Clouds, because that is what my horse likes.

For arthritis, I have had very good results with a product that hadn't been mentioned here. But for your horse, right now, I would take one thing at a time...following the emergency plan, and not add anything else into the mix that isn't recommended for the emergency diet.
