I don't know if supernatural or a miracle but here you go.

When I was still living a Spain a friend once visited me with his dog, a boxer. We took a walk with our dogs to the top of the Castillo and for some reason his dog took a leap over a wall with a 30-35m drop behind it. At the bottom just ground, rock and a couple bushes.

Needless to say that my friend lost his mind and I was sure his dog was dead. We went down there around the entire village with two other locals and when we got to the bottom his dog came 'running' up to us and he didn't hadn't have as much as a scratch, no bleeding and, as it turned out later, not a broken bone in his body.

As went back into to the village they local were just bringing the virgin Rosario out of the local chapel for a local holiday and that gave me some sort of miraculous sensation. I'm not catholic or anything but "something" watched over that dog that day and when I saw the virgin I had goose pumps on my arms. A crazy day.
