I love heelers, but feel there is a bit too much motion in this one. Faster shutter speed next time! Also, moving the dog left of frame. It's looking down into the very bottom corner and out of the frame. The viewer follows his gaze out of the frame, and out of the image. There is really no reason to look at the rest of it. It's kinda like the first chapter telling you how the book ends. That works sometimes, but not here, IMO.
