Thanks for giving us an update like this its very interesting, although I am sorry he has to go through, anything at all, I was surprised to hear of his hip score, although I did know of a mal who had a score of 69, even with this score, the dog did not show any discomfort in the past and enjoyed working in harness, although now he is getting on in years, its possible this may have changed. good luck and I pray for continued improvement.
