Yes, you read that right. A thousand people gathered in Berlin. These people identify as dogs. They don't dress up as dogs. They claim to be dogs.

I have no idea what to think about this. I can see why someone might want to identify as a dog. Dogs are pretty special.
I am not sure how this could work. I guess it is harmless. I still don't see how this would work.
