Dogworld

After a catastrophic event on Earth, humanity is directed underground and into pods for their safety. You are told that the surface world is dangerous and uninhabitable, and inside the pods is the only safe place to be. But when you are launched from the underground in a freak accident, you realize that the surface is just fine and there's more to this world than you thought. The surface is teeming with life, except... they all seem to be dogs. And some of them talk.
