If an alien arrived on Earth would we recognize it as an alien? I guess we always assume an alien will look humanoid but what if an alien looked - well - more like a dog? So here is my question to you. Is this an alien? Have they already arrived?

Need another look to be sure?

I'm not at all sure. But if it is just a plain old ordinary dog and the old adage is true that owners look their pets - I wouldn't want to meet this dog's owner!
