Dogs, depending on the circumstances, are able to determine whether a person is cheating them. This is evidenced by the results of a study published in one of the main printed editions of the Royal Society of London - Proceedings of the Royal Society B.
Scientists from the University of Vienna conducted three experiments in which 260 dogs of various breeds took part.
Two opaque bowls were placed in front of the animals: one was empty, and the other contained a treat. One of the volunteers, whom they had never seen before, began to tell the dogs which bowl the food was in. They chose the indicated container, received their reward, and eventually began to trust him.
Then, in the presence of the dogs, the new stranger carried food from one bowl to another while the person from the first part of the experiment watched what was happening.
Then this procedure was repeated, but without his presence.
After that, the scientists repeated the first part of the experiment and came to the conclusion that dogs ignore the advice of a person if he was not present when the treats were shifted.
Even more important, experts consider the fact that about half of the animals tested did not follow the advice of this person if he saw how the food was moved, and then tried to convince the dogs that it was actually in an empty bowl.
This, according to scientists, indicates that dogs are able to distinguish between human lies.
It is noted that similar experiments have already been carried out with children under the age of five, as well as with macaques and chimpanzees. In all the studies, experts concluded that children and monkeys were much more likely to trust the advice of an obvious liar than dogs.
