Each player claims a dog house. Create the game path with the 10 extra-sturdy game squares. Move the plastic puppy along the path - when you land on a space that features the dog in your dog house, you collect dog bones. As the puppy moves, so does the game path, so it never ends - and it's different every time you play! When all the dog bones are collected, the player with the most is the winner.
