A tighter crop on the left would have made this a better photo. Cut out all of the up close hurdle. It's a great capture. While there are "lines" here, Imo they are not leading in a helpful way to the photo.
I'm a sucker for good dog photos. Looks like this pup is really enjoying himself and having fun. Nice focus for an action shot. I think I would have liked to see it cropped a little closer. 8
