MRI Study Finds 12 Dogs Distinguish Human Emotions, Including Some Negative Faces

Q: Could your dog's ability to tell when you are sad or angry depend entirely on their specific breed?

No. Breed may influence how strongly a dog attends to human cues, but the evidence does not support the idea that a dog’s ability to sense sadness or anger depends entirely on breed. The Vienna study found that dogs’ brains could distinguish happy human faces from neutral and negative ones, and broader brain activity suggested they may also process some differences among negative expressions such as fear, sadness and anger. That points to a general canine ability, not one limited to a single breed. Breed still matters as a possible factor. Most dogs in the study were border collies, a breed known for being especially responsive to human signals, so the findings may not map perfectly onto all dogs. The researchers themselves flagged that as a limitation and said larger, more diverse studies are needed. What the evidence suggests is that breed is only one part of the picture. Dogs likely vary because of temperament, training, life experience, and how bonded they are to a person. The researchers also said dogs may rely on more than faces alone, using body language, movement, tone and other cues to tell whether someone is upset. So a border collie may be especially quick to pick up on a frown or tense posture, while another breed may be less reactive or show it differently. But current research supports the view that emotion-reading is a broader dog trait, with breed shaping sensitivity rather than determining it outright.

An iScience study found dogs can separate happy from neutral human faces and, in some cases, distinguish among negative emotions using MRI scans of brain activity.
Eight dogs showed reward-region responses to happy versus neutral faces, while scans from 12 dogs found they could tell happy apart from sadness, anger and fear.
Whole-brain patterns went further: the dogs distinguished sad from fearful and angry from fearful, but not angry from sad, suggesting they detect different kinds of threat.
Researchers said the work is the first evidence dogs can distinguish between two similar human emotions, though the tests used photos and mostly border collies.
The findings add to evidence that domestication tuned dogs to human cues; in real life, they also read body language and scent signals linked to emotion.
