One interesting point I will give to "non-sedaters" is that due to muscle relaxation that occurs with sedation, at least in theory, the joint should be tighter appearing in an unsedated animal. I have never cared enought to evaluate for myself if one can observe this variation in the same animal comparing awake versus sedated, though. Since OFA asks whether sedated or not one would expect the radiologists to compare based on the level of sedation if there is any noticeable effect. From a veterinarian's(and hopefully breeder's) diagnostic standpoint, I would prefer to see the maximum laxity on my films to have a better idea if dysplasia really exists. If one's goal is pass at all costs, you should also be running a radiolucent strap around the hips to force the head deeper into the acetabulum, the exact opposite of what PennHip does. I AM NOT suggesting anyone here would stoop to this unethical step! I guess my point is I would rather have a sedated "good" versus a non-sedated "good" if one could eliminate human error in evaluation. Just food for thought.
