I really need to see your dog's walking/standing video or see him(her) directly before we can do anything to help you. I strongly recommend you take your dog to your Vet as soon as possible. For any bone/joint problem, doctor's early examination is very important. I can't tell you any comments by the signs you described because I can't image them.

If you have a copy of x-ray, you can post it in this website and I can try to review for you.
If you do not know how to post it, please ask Amy.
