Players are dogs working together during a series of tests (rounds) given to them by famous Dogtors such as Sigmund Fetch, Collie Jung, and Bark F. Skinner! Each round one player is the Dogtor and ensures that the dogs are following the rules. All players start with 3 bones. If they ever make a mistake they lose a bone and if one player is out of bones the game ends immediately. Whenever you are a bad dog, you lose one bone. The Dogtor then resets the total test value to zero and play continues until all dogs are out of test cards. The game end immediately once one dog is out of bones and all players fail. However, players may share bones in between rounds as long as each player has at least one bone but no more than 3 bones. If all players still have bones at the end of your final round, you pass!
