Tonight, a friend from church came over to help me with some yard work, and one of out projects was reinforcing the base of the dog pen fence to stop Belle from exiting at her leisure. We identified her latest bolt-holes and we blocked a lengthy section of the fence with logs, rocks and scrap lumber. It wasn't easy work but we did a thorough job and we tested it by putting the dogs out in it. Belle went from one spot to the other and was frustrated every time so we pronounced it a success and went inside to drink beer and talk reloading in my shop.
About fifteen minutes later, my phone rang. It was my neighbor across the street. He called to tell me that Belle was out on the driveway just sitting at my door.
Sure enough, I opened the door and she walked in nice as you please.
