I'm a Japanese/Australian born in Kanagawa, Japan. A translator by trade, I hunt, breed, and show the Nihon Ken.
I like Akane Go's hips better.One thing that I've noticed in your x-rays is that the kneecaps are not centered. Still lots of information in the x-rays, but the under-rotation shows up as a squarish joint instead of a ball joint. The flattened portion is where the ligaments are attached (normal feature), and aren't seen if the legs are rotated more.
If you look at Claire's/Kaiju's FB album with the x-rays, you can view how the kneecaps are lined up.
@ayk do you mean the lower part of the legs need to be turned inward a bit more to straighten everything?
Thanks! I'm teaching my vet how to take hip x-ray's haha.
