Savvy the Sheltie is 1 year old. She is very hyper when I take her for walk. Everything form school bus to dogs to people to birds gets her attenion and often tounge. She does not heal to my left side as we trained her at puppy class. She turns around and lashes out at anything that gets her attention. Any ideas how I can heal walk her to my left when in real world ?? She does that when there are no distractions but as soon as something gets her going she is all over the place.
