Here’s a great video someone sent me from the Clicker Training website. Even if you don’t use a clicker, this provides some good lessons. I love how this video demonstrates calm and persistence to achieve a calmer dog.
I wish there was a little more narration, but it’s worth watching through to the end because as the video progress, you can actually see the dog start to calm down. At least until the owner shows up at the end (isn’t that always the way!) But even then, you can see how the training has allowed the dog to regain control of himself faster and that the dog is now seeking guidance in how to behave.
