Bob and I both share similar circumstances, however, instead of one, I have three. If you are going to be gone that long during the day, I highly recommend getting two to keep each other company. All three of mine roam the house freely except the bedrooms, although they spend most of their time in "their" room sleeping during the day. As for the potty issue, I put training pads down in the laundry room which has worked out well. There is also now DOG LITTER you can get at Petsmart that is more absorbent than kitty litter.
