i love the focus on the face - it is fantastic - with good details - i just wish we had a slightly different composition and perspective - the brown object in the background is a bit distracting - would a crop help? perhaps
Great face, great angle and nice job on the tricky exposure a black and white animal presents. I would move me or the dog or both over a little so there was only deck in the background and nothing would distract the eye from the dog.
