University of Vienna study confirms dogs recognize human emotions

A study published in the journal iScience provides scientific evidence that dogs can recognize human emotions. Researchers from the University of Vienna used brain scans to observe how dogs process various facial expressions, including happiness, sadness, anger, and fear.

The research, led by Laura Cuaya, involved scanning the brains of eight dogs—including Border Collies, a Labrador, and a Golden Retriever. The results showed that happy human faces triggered increased activity in brain regions associated with higher cognitive functions and reward processing, specifically the temporal cortex and the caudate nucleus.

Unlike primates, whose social abilities may stem from a common ancestor, the study suggests that dogs developed these social skills through a unique evolutionary path driven by domestication, allowing them to understand and cooperate with humans.
