Does anyone know how to properly measure rear angulation? If the upper and lower thigh bones are set to say 90 degrees, where is the hock suppose to be positions in relation to the body and what is the angle of the upper thigh to the pelvis? In other words, is angulation measured with the dog standing in a natural stance (with the hock close to the body) or in a show stack with the rear leg extended?
I have a couple papers by Dr. Morton Goldfarb (SV judge), but can't quote from them per his request in the front of them. Suffice it to say that even he doesn't know what exactly was intended by the FCI's description of the upper and lower thigh bone meeting at an approx. 120 deg. angle. He surmises that it is with the hind leg extended, metatarsal perpendicular to the ground.
I'm trying to track down a biomechanics book that covers canine gait (the more technical the better, might end up being part of a class project). If anyone knows of a book let me know, and if not then I will let everyone know if/when I find what I am looking for.

If the dog is stacked "correctly" the ideal angle is always the same.
(correctly being the German stack, not the AKC short front leg and pushed out long rear one)
The best stance in my opinion to see the true structure of the GSD is the old school alert stance. No stacked rear legs under the body. Both legs out to the rear and forward body position. There are pics all over the web of the old school dogs stacked with both legs to the rear. . .just look.
