I just started my 9 year old girl on this product and I can not say enough good things. When she was 6 months old the bone in her back leg died due to a genetic defect and had to be removed. This threw her in to early severe arthritis. Some days she would just move to go outside to potty. I’ve had her on rimadyl all these years when I realized It was destroying her kidneys and health. I’ve tried so many all natural products the glucosamine anything to help her. Nothing has helped …..UNTIL NOW… yesterday my baby ran in the back yard hopping all over the yard for 5 hours …something she hasn’t done for so many years. I’m so pleased with the product. We have and vet appointment Wednesday and I’m telling her all about this . THANK YOU THANK YOU THANK YOU… from me and Reese.
