I was hoping not to have to post again, but, Sasha seems to have had a set back or possibly a new injury. Two days ago we noticed her favoring her right front paw. By last night she could hardly put any pressure on it at all. The temperature here has been extreme over the past few weeks. The current temp. has dropped 30 degrees over the past 3 weeks. We've noticed before that temperature extremes seem to bring on these limb problems. And that the pain will tend to "hop" from one limb to another. She has been feeling and looking so good the past few weeks, I was hoping we had the problem solved. It's possible this is a new injury, but from her past history, I'd probably guess it's not. What would be our next step with her, GM? Thank you, in advance. Kathi
