This is lovely. Running with dogs is such a beautiful experience and brings me so much joy. I love watching the dogs have so much fun running.
Have you tried running with her with canicross equipment, so a specially designed running harness for her and you wear a belt, situated low down on your hips and you are connected with a bungeed line? This way, you can be handsfree, if she pulls, it actually helps you and it may harness her inner sled dog.
