This is exactly what the dog saw on one of her walks. Note that. Her walk. Not mine. I’m just there. 

The picture looks  a lot like some kind of studio set up.

It isn’t.

We found it as you see it. 

We’ve been walking by it for a couple of days. We were waiting for a little rain to brighten up the details some. She had no interest in it. After the scene started sparkling from the rain water, she trotted right to it and I took the picture. 

All I can tell you is listen to your dog.
