Amazing Product
I started using this for my lab-boxer mix who is a 118 lbs (healthy girl). However, being true to her lab side she has hip problems (sure her weight is not helping). However, this products really helps. Anytime she is out for any length of time, I notice the different in her ability to get up and down.  I use Crystal Star products myself, and was pleasantly surprise that the products provides my doggie with the same holistic benefit to life/aging challenges.
