When I first saw you photo, the first thing that came to mine was the movie "Caddyshack." GFreat pose of your subject with nice details visible. I really like the look on his face. Good composition too. I can tell he was in bright sunlight and considering that, you managed exposure well in my opinion.
Great shot. We have some 'dogs' in our area, but they are hard to get to pose. They are down their burrow as soon as you stop.
