The Secret Triwizard Challenge

Yeah, you're not actually gonna do that because dogs are too good for this world, and you'd feel bad killing it... unless you're not killing anything because it was a rock before? Is a transfigured rock even alive because technically it started as an inanimate object? Unless rocks and dogs are simultaneously alive and not alive because all rocks can be dogs and all dogs can be rocks? HOW IS TRANSFIGURATION ETHICAL???
After you have a minor moral crisis, you decide to do something else, anyway.
