6 - Nice pose and clarity in the eyes. Perhaps a little more width in the framing for visual balance may have given this an edge. Toning works well but a little more 'depth' / contrast (difficult with the coloring) may also have made this even better in my opinion. Slightly tighter crop at the bottom too.
I like his expression and the use of the milk bone, but the angle seems a touch "off" as does the crop. The focus is good. I think the design of the rug is a distracting factor as well. 6
my what a well behaved dog. composition feels awkward to me as it feels like you tried to force the feet in, though they don't seem as important as the head in this shot. dog's left side feels a bit over exposed and it doesn't seem warranted to me.
