I have been using this product since 2003. I had one rescue shar pei with mobility issues and after using this product, he was able to go up and down stairs without pain. My newest Shar Pei has been on this product since he was a puppy. He is thriving. His mobility is smooth. His allergies and coat are beautiful. He will be seven years old in October. I believe this product keeps all my fur babies healthy and strong. Kudos to you!
