Not a bad running dog shot, but higher speed running than this is typically where you get the best results. Like that one. There's another one somewhere on the site too that illustrates what I'm talking about but I can't find it. The other one is a head-on shot like yours, in BW.
A nice clean portrait of a dog running towards the camera. I am sure you are very fond of this image, which I suspect is your dog. However, for an outside viewer there is not much of interest. It is clean, its cute. a nice snapshot but nothing more.
