She's pretty for sure. I might crop some off the bottom to put the subject more toward the bottom third and to slightly enlarge her. The top is a good backdrop for the shot. She's a beauty definitely ... the pup and the picture.
I'd say crop it a little all around and a little more off the bottom and left side. More dog, less scenery. I agree with Steady about the collar, too. For an action shot, she might look better herding sheep than cattle. Maybe jumping through a tire at an agility trial.
