Border Collie!

I took my neighbours dog out for a walk yesterday to practice pet photography. I wanted photos that would show how active and happy this dog is. She rarely stands still, doesn't understand the word "stay" and I am confident she laughs at me when I say it!
I would appreciate any feedback, especially related to posing and post-editing. I am just learning Lightroom now and haven't tackled Photoshop. Black and White is also new for me, especially with a black and white subject.
