When I was 4 years old we had a big dog that had bitten many people. One day, I climbed down inside a rock lined well on an abandoned farm. That dog went nuts, and, as luck would have it, a man who live half a mile away was walking by, and the dog wouldn't let him pass. It kept barking and running from the road to the well. Finally, the neighbor realized that there was a problem, and he came and got me out. If it hadn't been for that dog, I would not be writing this today.
