While dog keepers realize their dogs can read their moods accurately, scientists have always been a little doubtful. Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria, we finally have some convincing evidence.

For their study, biologist Corson Miller and his team exposed eleven selected dogs to digital images of women that were either angry or happy. Half the dogs were rewarded for touching the screen when shown a happy face, while the other half got their treat for selecting those that appeared angry.

Interestingly, the dogs were not provided with the entire face. Some dogs were shown only upper halves while the others observed lower halves. That’s because the scientists believe humans show their emotions on their entire face.

After some training like how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions ,the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face. The researchers concluded the dogs were smart enough to read human emotions.

They also found those being trained to read angry expressions took a longer time to learn. They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly. However, once the smart dogs realized they were getting rewarded, the trepidation seemed to disappear. In fact, the dogs had such a good time playing the computer “game” that scientists had a hard time keeping them away from the touch screens after the study was completed.

The researchers also noticed only dogs with a male owner had a hard time understanding the expressions correctly. Since the touchscreen models were all females, this confirmed what has been observed in previous studies—dogs are more efficient at reading facial expressions of people that are the same gender as their owner.
