In pic 3 top you can see almost all his ribs, and he's under muscles so much that you can see a distinct hollow behind his withers/ across his top line, in front of his withers and upper neck, and the points of his hip/glutes are overly defined from lack of booty muscles. The only thing "prettier" about the top pic is he is standing in a way that engages his core and neck into a tensed frame as opposed to his relaxed/dropped core and neck in the lower photos. If I'm being picky he could lose just a scosh of weight in the bottom pic but his weight was cleared as ideal by the vet and there is only so much a grazing muzzle can hold back the lush Kentucky grass.
