The only faults I can see with Reggin are fairly minor. He's got a high tailset. The planes of his head don't look even (he's got the sloping forehead). And his topline doesn't slope down, but that also changes depending on which standard you read. I can't see too much from those pics, to be honest. My overall impression is that he's a pretty true-to-type dog. A little on the thicker side, but still correct enough. He's got a lot of strengths: tight feet, short loin, good muscle tone, looks like an arched neck if he were stacked up, clearly a masculine male dog without being overdone, better front angulation than many, proper head/muzzle ratio (at least for UKC). If he were registered UKC, I'd think you could finish him. He looks big, but he may just project himself like that.
