A shot of my daughter's working cocker spaniel, Ronnie, while playing fetch at the local park recently. I was laid on my belly shooting with a Nikon D780 and Sigma 150-600 sports lens at 600mm f/6.3 @ ISO 800. Shot in natural light, on a fairly bright day, with trees some distance away in the background and a shallow grassy slope immediately in front of me. It was quite a challenge to get a shot in focus, as I was shooting through the viewfinder and not via live view.
