A cheerful take on the "dog ate my homework" excuse and the "can't teach a old dog new tricks" adage, "A Very Old Dog" follows the player-character's attempts to housebreak a grad student's science experiment.
This experiment is a playfully menacing pet, and your attempts to train him involve diverting, but straight-forward, puzzles. Unfortunately, a bug in the game's auto-naming feature can break the game, so name your new pet yourself, and you'll likely enjoy this little romp.
