I have 3 with LP and all are grade 3 and not limping or in pain and I'm not having surgery as long as there is no pain or limping present. Weight management and limiting jumping has helped mine avoid surgery. But of course I'd go to a board certified surgeon for this type of surgery. I personally am not electing surgery due to no pain or limping and my dogs still run full blast outside and in and out doggy doors with no problems
