Sadly, animals are often born with deformities. There's not much that can be done about that. But did you know that dogs can be born with a tail on its head, too?
This actually has happened to at least one puppy, and pictures of the doggy have gone viral.
This is Narwhal. Narwhal is a rescue puppy who was born with a tail on his head. He currently lives in Missouri but is without a proper home right now.
