LOL I had a dog that would do that...flatten me in 1.4 seconds flat or drag me over the ice and snow. You can see all the energy in this guy...nice capture!!

Because hes moving, its hard to grab that 100% focus on him, but I am sure you didnt have time to prepare, let alone manual focus - so there is more focus on the background than the moving subject.

A little light in his eyes would be nice as well, but you can always fix that in processing.

Great composition and even better that you have the people in the background with the other dog.....really shows how wild the running dog is

Great shot, very emotive and the photo still tells a story!!
