If it were me I would have the specialist look at her. She's so young that doing surgery now would probably be for the best because she has alot of years ahead of her and you want her to be comfortable. Don't get me wrong cosequin is a great supplement but I don't think it'll help enough on it's own for a issue like this. It seems to help more with earlier stages of arthritis. But that's just my silly ol' opinion Good luck with her! She's a cutie!!!
