James, I just looked at this again...I love the last shot. I'd leave the ball in and the rear foot. But I would take the catchlights off the ball.

Is the color right? Does the dog have yellowish/brownish/dingy fur, or should it be white? Just asking, I pulled it into Photoshop and picked a white point in curves on the dog's forehead and I thought the ball and the bone looked better...since I've never met the dog I can't say what is accurate.
