It was quite a surprise how good the new "controlled environment" went for Henry on Friday. He did not have the run of the backyard nor did Walter. I was back to the way I use to train puppies, especially those only 12 weeks old. Once they eat, wake up from a nap or stop after playing hard ... I opened the patio door and he or they went outside. Just like he was taught before I bought him, he peed immediately. But this wasn't so much about house training but prevention of destroying my yard with his digging. I wanted to control what he did in the backyard.
