Query: This one works.

This video really works. I have two small dogs, a shih-poo and a shih tzu. They are adults and rescue dogs so neither of them had any socialization or training. I taught them both down in a less than an hour on one day. I also have been using this to train my shih poo not to pull when on leash. She has had more progress with this training method than with any of the others I have tried, including Cesar. I would highly recommend this video.
