Of course when we work with our dogs we are going to get excited. We are also instructed to get excited when our dog is not paying attention to us but what happens when we go to far. It is absolutely possible to be too exciting and scare the hell out of our dogs when they are getting over fears or if they are startled by our excitement and their temperament is fearful. Make sure that you are working at a level that helps your dog instead of hurting their progress.
