Canines’ brains, like human brains, are sensitive to acoustic cues of emotion. So you’re dog really can tell how you’re feeling. The researchers used MRI technology to peer into the brains of canines while listening to 200 human and canine sounds from playful barking to laughing and crying. Approximately 39% of the dogs’ vocal regions responded to other dog sounds, 48% to other environmental noises and 13% to human voices. But they found the dog voice areas in exactly the same location as human voice, meaning our pets are a little more like their master than we thought.
