My male lab/mix dog weighs about 130lbs. I think he is mixed with a large Pointer. He was x-rayed 5 years ago and had bad hip dysplasia in one hip. He is now having trouble getting up. I was told if and when he could no longer get up I needed to have him put down. Is there any supplements I can give him to prolong his life and can I give him asprin every night? He was adopted and about 10 years old.
