Spunky Level IISpunky Level II was developed for the canine with symptoms of arthritis beyond the reach of glucosamine alone. A proprietary blend of Glucosamine, Hyaluronic Acid and MSM helps manage inflammation and pain associated with overexertion or arthritis and helps aging dogs continue their activities with increased vigor. Our Spunky formulas were designed specifically for the companion animal eating modern, highly sanitized and processed food.
