Funny you should mention that. My son took the game to a friend's house, and he also left it briefly unattended around a dog who chewed up several of the pieces. Luckily, I had multiple copies, but I wonder if there's something in particular about the smell of Push-It pucks that attracts dogs?
Dogs love Push It too! Great marketing material. My son did some extra chores to earn payment for replacement. We're still having fun with this game.
