Dogs can read your face and understand your emotions, science confirms

A new study has found dogs can distinguish human emotions from facial expressions, including fear, sadness and anger. Here's what happens inside their brains.The discovery builds on years of research showing that dogs are unusually attuned to humans.

The findings, published in iScience, provide the first evidence that dogs can distinguish between different human emotions that are all negative.“This is the first demonstration that the dog brain can distinguish between emotions from the same valence,” lead researcher Laura Cuaya of the University of Vienna told news agency Reuters.WHAT DID DOGS REVEAL? The researchers used MRI scans to watch what happened inside the dogs' brains while they viewed the faces of their beloved humans. A dog is seen sitting on the pavement.

Researchers said dogs may need additional clues, such as body language or voice, to make that distinction. A child plays with dogs on a hot summer's day.

So the findings may not apply equally to every breed or dog.DOGS AND IMPRESSIVE SOCIAL SKILLSThe discovery builds on years of research showing that dogs are unusually attuned to humans.Earlier studies have shown that dogs can combine facial expressions and vocal cues to distinguish positive from negative emotions.They can also recognise familiar people, respond differently to human emotional signals and even distinguish between familiar and unfamiliar human languages by their brain activity.The new findings add another layer to that relationship, showing that dogs can extract finer differences from a human face. They may not simply recognise that a human is happy or unhappy, but researchers believe this sensitivity may have developed through thousands of years of living alongside humans.As Nottingham Trent University professor Bridget Waller, who was not involved in the study, told news agency Reuters, dogs have been shaped through domestication to understand human behaviour, perhaps because reading us has been useful for survival and companionship.- EndsPublished On: Aug 12, 2026 17:05 IST
