It is said that dog is a man’s best friend. The fact might actually be true. The University of Sao Paulo, Brazil conducted an experiment on them to find out whether the dogs could assess the emotional content of human voices.
17 dogs took part in the experiment. Pairs of photos of someone looking happy or sad were shown before them. In addition to the photos, the person’s voice speaking in a cheerful or angry tone were also played.
Research revealed that the dogs spent more time looking at the facial expression that matched the tone of voice. This means that canines are actually capable of matching a person’s facial expressions with his voice.
Researchers say this might be an inherent capability domesticated in canines, which can go as far back as 30,000 years!
Now we can undoubtedly believe people who say they feel a connection with their dogs who react to their emotions on a daily basis.
