WELCOME to YT> Many of us on here are dealing with LP.. did they tell you the grade (1,2 3 or 4?). A great suppliement that many on here are trying is called Cosequin. It is a glucosamine chondriotin suppliment that will help strengthen his joints. LP can not be reversed but the progression can be slowed down. Also walks are GREAT for strengthening the muscles around the knee cap and with layla I do hydrotherapy- which is just swimming in the bath tub
i fill it up and hold her in it and she paddles for 5-10 min. If you search Luxating Patella on here you'll see MANY stories of LP and see how those who have had the surgery have done.
