Dogs can distinguish between emotions in a human face, study shows
BERLIN, Aug 11 (Reuters) – A peek inside dogs' brains revealed man's best friend can distinguish emotions in people's faces, researchers at the University of Vienna have found, providing what they said was the first ever evidence of such an ability.
In the study, researchers used machine learning to analyse brain scans of 12 dogs as the animals viewed images of human faces displaying different emotions, the university said in a press release on Tuesday.
Researchers found that brain regions linked to higher cognitive functions and reward processing — the temporal cortex and caudate nucleus — were activated only by images of happy strangers.

If you’ve ever suspected your dog can read your mind—sussing out through some canine intuition when you’re happy, sad, scared, or cross—you’re half right. Many dogs can do exactly that, but it’s not mind-reading that’s involved: it’s face-reading. That’s the word from a new study in the journal iScience, in which researchers not only established dogs’ ability to discern human moods by examining our facial expressions, but also pinpointed the spots in the brain where that processing takes place. They did this by scanning canine brains with functional magnetic resonance imaging (fMRI).
