"In the process of being domesticated, dogs gradually developed sensitivity to be able to detect signals threatening from humans, and their reactions were often calming, apparent compromises." - Sanni Somppi of the University of Helsinki (Finland - said.

In a recent study by the University of Helsinki (Finland), scientists tested on 31 dogs of 13 different breeds, trained to be able to stand in front of a display without chains, locked up. They were shown a series of photos of people with enough emotions such as fun, anger, intimidation or normal. The camera captures the eyes of each dog to see their reaction.

First, the dogs look into the eyes, then look at the mouth, nose . This shows that dogs not only judge human mood based on a part of the face but consider many factors. then put the information together.

Next, if faced with photos depicting people who are angry, they tend to avoid the human eye and often look downwardly under their teeth. Scientists conclude that dogs can fully identify signs of threat when people are angry and respond by compromising.
