Halloween // Costumes ideas for couples and their dog?

I’m trying to think of costume ideas for my partner and I and our dog. I would prefer it to be fictional characters and would really like it to be like a fictional couple and their dog or creature. So far I’ve only thought of courage, Muriel and Eustace, Jack, Sally, and Zero, and Shaggy, Velma and Scooby, and Team Rocket. Any other ideas?
