We did have a discussion about dogs being injured during the Penn-Hip exam, and I e-mailed Fred Lanting a link to the thread. Lanting, as many of you know, has written a book on Canine Orthopedics and Hip Dysplasia, and is a very strong supporter of Penn-Hip. He was extremely indignant at the suggestion the exam had caused injury.
So indignant I really can't quote his e-mail, even if I had permission to do so!
I am going to include one line from it, though, just to establish his credentials: I have been actively researching and teaching about HD since 1966. I would wager that far more people would trust my judgment than that of this [poster's name removed]
In addition to having a PhD, he got his license as a veterinary technician so he could actually be present and assist during orthopedic surgery, and have a better, hands-on understanding of orthopedic problems.
