How to you stop your dogs leash pulling? If your dog is pulling on his leash, the experts say that both you and your dog have developed a very bad habit. To get him to walk on his dog leash without pulling, you must change your behavior. Put him on his leash, ask him to “heal,” then move forward when the leash is not tight. If he pulls on the leash, stop right away and don’t move. When your dog turns to look back, call him back heal position and start again. If he pulls on the leash, stop and repeat the process. Move forward only when the leash is loose. It will be slow and frustrating at first because leash pulling is a hard habit to break. If you are persistant about not allowing your dog to pull you anywhere, he will eventually stop pulling on his leash.
