Nice composition and exposure. First you gotta think of it, then you gotta get the dogs to cooperate, then you gotta get your camera to pull it all together. You clearly did all three here - nice!
Thanks, Dave. It's really just the old dog honoring the young dog's point, and me thinking it would make a cool shot. They were just doing what they do....It's very seldom that they would cooperate for the sake of a photo....
