I’ve used the regular joint health chews and the advanced joint chews when they came out. With Desi, my now deceased Shih-Poo who had both rear luxating patellas that were bad, I used the regular joint health and they kept him surgery free all his life. Of course, I did curtail his jumping a little. Once Lucy apparently pulled a muscle in her leg (or something?) and I immediately started giving her the advanced chews. She was better in no time! I love Springtime supplements and have used them for many years for my dogs.
