I use Platinum Performance products- Platinum Performance Complete Joint.

I started my golden on the regular Platinum a year ago (without the extra joint support of the PP Complete Joint) and her regular right-hind limping completely quit. She is now on the PP Complete Joint. Platinum and Cosequin are the only products I trust, due to their solid research and testing, and their excellent customer support (including vets and nutritionists). The use of SLS is really scary, and if I used the product, I sure would be calling and raising a fuss about this.
