The Wisconsin Veterinary Medical Association will be inducting three Labrador Retrievers into their Pet Hall of Fame. Their human's car rolled and she was thrown from the vehicle, suffering severe injuries. While one of the dogs remained to look after her, the other two ran to a house a mile away, then scratched and barked at the door to draw attention. When a man came outside to look, the dogs took him by the sleeve and tugged to get him out to the road, where he could see the accident.
So how much do dogs understand and think? These three performed some remarkable feats. There are humans who would not have figured it out. How did they know to have one of them remain behind? How did they know to go for help, and where to stop? How did they know they needed to get the man at the door to where he could see the accident? It does make a person start to wonder just how sentient another animal can be.
