Gemma maybe I am putting it on wrong but Jack's Easy Walk harness goes no where near his neck ! It pulls on his chest when he pulls me but not his neck. He also pulls less because of the front hook.
You're right the harness doesn't come near the neck. Sorry I might wrote it wrong. For Corey he likes to walk in front of us (he doesn't pull though) and since the hook is on the front, the leash touches his neck area, it's hard to explain . But i notice when we rotate the hook to the the back he scratches less often.
