Can You Tell What Your Dog Is Feeling?
“Look at him, he’s so happy!”
Most pet parents will tell you they can tell what their pet is feeling simply by looking at them. For years, mainstream scientists have dismissed reading a dog’s emotional facial expressions as wishful thinking. New research suggests we may be able to correctly guess our pet’s feelings after all.
Back in 1964, Dr. Niels Bolwig, a pioneer in behavioral biology, described the facial expressions of dogs and their corresponding emotions. In 1970 Dr. Michael W. Fox, later of the Humane Society of the US (HSUS), dismissed Bolwig’s research and claimed pet dogs were unreliable test subjects for facial expressions. Fox postulated that due to domestication, dogs had learned facial expressions that worked best to achieve their goal, especially when their goal was food. Since then, little research as been conducted on dog’s facial expressions. Until now.
Teams from the psychology department of the Pennsylvania Department of Corrections in Marienville (you read that right - a prison), and tiny Walden University in Minneapolis (with help from the University of Florida) decided to see if humans could accurately read a dog’s emotional facial expressions. The scientists took photographs of a Belgian shepherd police dog, Mal, as he experienced different emotions. For example, they praised Mal to elicit a “happy” reaction. The handler reprimanded Mal to create a “sad” picture. A jack-in-the-box was used to “surprise” Mal, and a repulsive medicine that Mal strongly disliked was used for “disgust.” Mal disliked having his nails trimmed; that’s how they captured “fear.” To cause “anger” was easy; they suited up a police officer as a bad guy. Each photograph was a close-up of Mal’s face and head.
The pictures were shown to 50 volunteers divided into groups based on their experience with dogs. Their findings were surprising.
“Happiness” was the most accurately judged emotion in the study. 88% of the study participants correctly identified “happy” while only 37% identified “sad.” The next most predictable emotion was “anger” at 70% judging correctly. 45% recognized when Mal was “frightened” yet only 20% spotted “surprise.” A scant 13% knew when Mal was “disgusted” by the bitter medicine. Then it gets interesting.
This study found that people with minimal
