well with a little more description that I provided my vet, I told him that she occasionally will drag her left leg as it comes forward, like she is stumbling. He decided to measure her front two legs, and her right leg is a bit shorter than her left. Causing an irregular gate, and added wear and tear on her front left wrist, thus causing what he said to equal a "bum knee". the gluco has helped, along with an occasional asprin, The only thing that is now causing the limp is when she goes on a full out sprint, which I try to eliminate, but as you know, we cant always do that. So its just a matter of keeping her in control and limiting her running, and she seems to be doing better....thanx for all the replies.
