Poor baby. And poor you! How stressful! I have never personally dealt with one, however-I own a 22 yo who was so severely windswept at birth the vet recommended euthing him. Somehow the breeder used PVC and splinted him. I do not know the details, unfortunately, and have not been able to find her website in about 3 yrs(I just looked for you). Anyway-he was fine. I bought him as a 4 yo, and he has not ever taken a lame step, hunted, shwon, etc, until about 3 yrs ago, when he started with arthritis.
So, hang in there-they can be just fine. Follow the advise of those who know, and your baby will straighten up and lead a great life!
