Jake and Lucy moved into their new place late August and Main St is very busy so they had to learn to stay on the porch unless they are on a leash. In the first week they had a fail for running down the steps because there was a German Shepard barking at them from the sidewalk, but they did come back up on the porch when I told them to. Week 2 was not good for Lucy as she had about 4 fails but came back right away when I told her. Week 3 and no fails so far. Its like there is an invisible barrier that they have learned not to cross unless on leash.
