I was taking Duke for a walk around our house, which he really enjoys because there is no collar or leash required. We got down to the back yard and I went down HARD. He went back up to the house, and my wife came out and helped me up and helped me back to the house. She has issued a decree that I must always have a working cell-phone on me when I leave the house - no exceptions. Duke is a great second line of defense, but how can he help me when my wife is not home? She's also going to call on our doctor to get a waiver to let her leave work when I might be in trouble. Getting old ain't for sissies.
