The harness solves the pulling issue on a daily walking basis. The Front-clip changes the point of leverage. Every time dogs try to pull and the leash gives a tug on their chest to the side when the leash is attached to the front of them, it will force the dog to turn toward you and so stop them from moving forward. So if they pull, they get turned. And if they turn, they aren’t heading forward which is where they want to be going and why they are pulling.
