‘Early results from studying about 100 dogs suggested they had some insight into human emotions, and could “differentiate between happy and angry verbal tones”.
But the tests had not yet proved if dogs were also picking up on emotional cues from facial expressions.
Malaysia-born, Ms Yong is seeking a further 50 dogs for her continuing research, with owners also having to be present during the testing, at a university laboratory.’
There is no doubt in my mind that dogs can pick up different tones of a human voice. I am not sure about facial expressions though (I have trouble doing that myself sometimes).
The lesson here is – next time a client says to me that they can’t pay the bill on time, their dog will pick up the frustration in my voice.
