A dog has an instinctual desire to push back when you push on their chest. By wrapping a collar or harness around them and attaching a leash, you are putting pressure on them that they return in kind. It‟s an instinctual reaction and it isn‟t abnormal. But, it can make walking your dog a painful experience. To avoid this from happening, you need to keep your dog from putting that pressure on the leash. The more pressure they create, the harder they end up pulling.
As the owner and the holder of the leash, your control over the walking experience is absolute – or it should be. The walk begins the second you pick up the leash, the moment your dog realizes that they are about to go for a walk. The training to control a pulling dog must begin at this exact moment – reigning in all that excess energy before it can be transferred into pulling your arm out of its socket.
