The dog seemed to intuit that something huge and noisy was coming up. Kind of like animals escaping and hiding before earthquakes/tsunamis. One might postulate that humans have less of such a sense because we rely on thinking and not intuition. I even heard how like Native Americans and Australian Aborigines had more of these traits when they had to survive in nature. Cats are known to hide before vet appointments. Just ask my old neighbor; it was uncanny.It is a good question. Animals have instincts, but do they have consciousness? I would think they do. Notice anything in this gif?
