Dogs Understand Human Perspective
Dogs of course do make a study of the family that they have become part of, or at least the smart ones do. In fact the whole subject of dog cleverness needs to be properly investigated. The best are not automatons simply channeled.
We had an excellent farm dog who simply chose to not eat what we would not eat ourselves or directly give him. He still hunted out the pests, but then brought them to us for disposal. And he always acted in an intelligent manner.
Knowing this, the following item is unsurprising and is actually a nice exercise in experimental design to ferret out the actual details. It still needs to be applied against the population of dogs.
Dogs understand human perspective, say researchers

Dogs are more capable of understanding situations from a human's point of view than has previously been recognised, according to researchers.
They found dogs were four times more likely to steal food they had been forbidden, when lights were turned off so humans in the room could not see.
This suggested the dogs were able to alter their behaviour when they knew their owners' perspective had changed.
The study, published in Animal Cognition, conducted tests on 84 dogs.
The experiments had been trying to find whether dogs could adapt their behavior in response to the changed circumstances of their human owners.
It wanted to see if dogs had a "flexible understanding" that could show they understood the viewpoint of a human.
It found that when the lights were turned off, dogs in a room with their human owners were much more likely to disobey and steal forbidden food.
The study says it is "unlikely that the dogs simply forgot that the human was in the room" when there was no light. Instead it seems as though the dogs were able to differentiate between when the human was unable or able to see them.
The experiments had been designed with enough variations to avoid false associations - such as dogs beginning to associate sudden darkness with someone giving them food, researchers said.
Dr Juliane Kaminski, from the University of Portsmouth's psychology department, said the study was "incredible because it implies dogs understand the human can't see them, meaning they might understand the human perspective".
This could also be important in understanding the capacities of dogs that have to interact closely with humans, such as guide dogs for the blind and sniffer dogs.
Previous studies have suggested that although humans might think that they can recognise different expressions on their dogs' faces, this is often inaccurate and a projection of human emotions.
"Humans constantly attribute certain qualities and emotions to other living things. We know that our own dog is clever or sensitive, but that's us thinking, not them," said Dr Kaminski.
"These results suggest humans might be right, where dogs are concerned, but we still can't be completely sure if the results mean dogs have a truly flexible understanding of the mind and others' minds. It has always been assumed only humans had this ability."
