Hmmmm. Honestly, his condition looked better when you got him than now, and he looks a tad old for his age. I see a lot of detioration along the topline.
Structurally, he's fairly solid. Got an odd-shaped back. Not sure if I'd call it true lordosis or what, but it deeps down before peaking on a steep croup. The angle of his pelvis, I think, is too rocked back and disengaged from his midsection. Legs are good, but are they actually that thick, or chronically stocked up, or what? The right hind in the first pic almost looks like it's got lympedema going on. What's his breeding?
