Oh gee. The saddle looks way too small. Her girth has slipped way up into the groove behind her elbow & probably is not very comfortable, but more than that she is standing is a very self-protective posture. If I went out in the field and found a horse standing like that, I'd think belly ache or some pain in the hind end. I was going to write "pain in the rear" but that's come to have other interpretations..
All this would be allowing for the fact that cameras stop action and this may be the only moment in her life when she ever stood in that posture. If that is her norm, I'd say she's in pain. Which of course, you already noted. Oh - question - does she seem uncomfortable when she is not saddled? Nancy
