At the moment I am working four days a week, this may be only temporary or it just may be a permanent thing if I am lucky. In the past there has always been someone around during the day to let my little dog out when she needed but things change as you all know and nowadays if I'm not home for any length of time I either have to leave a door open a little bit or shut her in. This morning we solved that problem very simply with a doggy door that fits into the frame of the glass sliding door. It took all of 20 minutes, cost nothing as we got the old Murray Pine lining boards for free and it works perfectly. I have to get a heavy piece of clear plastic for the little door but it still beats leaving this door open all day and coming home to a freezing house and puddles on the floor if it has been raining.
