Nala is a big, strong dog and she pulls on leash because she likes to sniff things, so her owners thought that by keeping her on a short leash would fix their problem. In reality it just frustrated Nala, which caused even more pulling. Tonight we taught her owners that by letting her sniff she would actually walk better. Her reward for not pulling was the ability to move forward to the next scent, and she walked better than ever. If we make no changes nothing will change.
