Humans aren’t the only ones that convey emotion through nonverbal behavior: animals do too.
New research by animal behavioral experts has found canine emotions are betrayed by specific facial movements, such as raising their eyebrows or cocking their ears.
Using high-speed cameras, researchers in Japan found when dogs were reunited with their owners they tended to move their eyebrows upwards around half a second after seeing them.
The study entitled “Dogs show left facial lateralization upon reunion with their owners” was published in the journal Behavioural Processes.
