By the time our third walk with Chandler came around, I could see real improvement. Chandler began walking very well on the leash today and rarely pulled. When he did pull he stopped, backed up (to release the tension on the leash), and looked at me. I was amazed. This dog has come such a long way in a very short time. It just really goes to show that if you put the work in, you can see the results almost immediately.
During this walk I added the "Wait" cue at street crossings. Although we had always paused at these places in our previous walks, I waited until Chandler picked up the behavior before adding the cue. When training any dog it is important not to try too much too fast. This can confuse a dog and set back progress.
