Wow, way to go Rex! It's a good thing you noticed him acting strange. Layla darts out the door sometimes, and it scared me to death when we lived on a busy street. Yesterday actually I came home from a couple of hours at work and everything was hectic with Scott working on the kitchen. After about half an hour I said "Hey, where's Layla?" He hadn't seen her either. She was in the hallway!!!!
Thank goodness she couldn't get out of the hallway, but if we had been in a house and didn't notice for half an hour that she was gone, I don't know what I'd do with myself.
