I have posted this somewhere else, but since this is about HOD: after having been limping for about an entire year, rest or no rest, I was worried that the HOD remainders would cause permanent lameness in Cam. X rays came out clear and no-one knew what was wrong. Deja plays hard and since they are my house dogs it was tough managing them both in limiting their fun, inside and outside unless I completely separated them. I decided to rehome Cam to a responsible Collie home where he would have a calmer life. I got some cr*p because of this, here and in the community. But I did the best I could and followed my gut. It was a very tough decision as he is an awesome dog with a golden temperament. The good news is that a month into his new home, he no longer limps. It came as a shock to me. But it was my objective anyways. Would he have recovered here? Maybe. I just didn't want to put his health in jeopardy by keeping him along with Deja.
