Hi Basil, another lovely capture and I really like the colour palette, that rich red/orange of the pan & water, the dogs are having a cracking time, like all dogs do.
Not sure what frames you have further on, but if you had that leaping dog just arching the one in the water and had more separation between the trailing dog and the leaping, how cool would that be, but in an ideal world...
Not sure what more DoF would have added, albeit it would increase your ISO and needed more SS. Perhaps dropping the whole frame down a fraction so you have a bit more at the foot?
I think overall it's well exposed and processed, perhaps a small midtown Curve adj, but.... just watch your sharpening on wet fur.
Keep the images coming and have a great weekend.
Steve
