My own boxer got arthritis early, and I started her on Nupro, the silver label for canines. I had to get it online or at specialty dog stores...but within weeks, she was back to running around and being her boxer self. I highly recommend it, and it has some awesome, natural ingredients. Give it a couple of weeks...But I've heard the same thing from many other dog owners.
