I find the Freedom Harness to be the most effective tool in training dogs how to walk with their handlers. The two Leash System provides a wonderful communication tool to guide our dog through the learning process. In addition, if you have a dog that is pulling or lunging, I find the front loop redirects our dog’s forward motion with very little effort. There is an immediate positive result with the application of the Freedom Harness biodynamic action. I highly recommend it for puppy training as well.
