This is awesome. I have literally hundreds of dog shots but none quite like this. Framing and action here is just so perfect. A nitpicker might say the focus should be more on the face than the body, but I've noticed more and more recently that when you have a great shot (and I mean Great - composition, subject, atmosphere, style, etc), all the little details like focus, sharpness, etc - they fade to nothing, leaving only a wonderful, unrepeatable picture.
