Sad Puppy Face: Really Trying To Tell You Something?

A new study suggests dogs use facial expressions to communicate with people. The story by Hilary Hanson was curated by and published in The Huffington Post.

It might seem pretty obvious to dog lovers, but researchers have found scientific evidence suggesting that dogs use facial expressions intentionally to communicate with humans.

That’s according to a new study was published Thursday in the journal Scientific Reports.

“The study adds to a growing body of evidence suggesting that for dogs, human attention is important during social interactions,” Juliane Kaminski, senior lecturer at England’s University of Portsmouth and the study’s lead author, told HuffPost in an email.

While most people already know that dogs make a variety of facial expressions, researchers wanted to know whether the expressions were involuntary displays of emotions, or whether dogs move their faces on purpose with the goal of communication.

To gain some insight, researchers with the University of Portsmouth in England enlisted 24 dogs of varying ages and breeds. The dogs were all “family dogs” with “typical” training backgrounds for pets, and went back to their homes when their part in the study was over.

The researchers aimed to figure out how the dogs’ expressions changed during different situations. In one trial, an unknown human faced the dog. In another, the human turned away from the dog. In the other two trials, the human performed the same actions, but also held a treat. The person was instructed to stay still and not respond to the dog’s actions in each trial.

The researchers found that the amount of facial movement in the canine was largely dependent on the human’s position, with the dogs being much more expressive when the person was turned toward them. In particular, dogs were more likely to show their tongues in a relaxed fashion and to make an expression many people think of as a “sad puppy face,” which dogs make by raising their inner eyebrows…
