Canine Committed
Short of taking up smoking, this is probably your best bet for the old slipping out early excuse. Obviously you'd love to stay to see where this third round of apres dinner inconsequential chat is going, but really, there's a living, breathing, potentially made up dog sitting back at your apartment with his legs crossed waiting for you to run your tush home to take him for a walk. A furrowed furry face is hard reasoning for any host to argue with. Just think of the poor animal. And if that doesn't work, think of the hardwood floors.
