What a great capture! Love the lighting, colors, the sense of motion.
IMO, the dog is too centered - I think more space in front of him would add to the feel of the shot (even at the expense of losing some of the water droplets...).
Such a pity you wobbled this. Could have ribboned (I might still get egg on my face). The lighting highlights on hair and drops, the feet in the air, the tongue, the composition. Now all you need to do is work on that Shutter Speed...
