Honestly, without better pictures, I wouldn't know whether I'd consider him breeding worthy or not. His shoulder is too straight for my taste, but his front legs look perfect from the sides. I'm not sure about his entire hind end. I don't know whether it's just his wonky stance, but his croup appears rather steep, his hocks look like they might be rather straight, and he may well be bandy legged on the back.
But, again, it may just be the way he's standing. I would want several pictures from each angle that were better quality, and I would want to scrutinize his pedigree before I did anything.
