What Dogs' Facial Expressions Mean

What Dogs' Facial Expressions Mean

Dogs really do use those puppy dog eyes on you...according to science. A study published in Scientific Reports, found dogs make significantly more facial expressions when a human is facing them than when a human has her back turned. Even more surprising, when food was brought into the picture, the dogs in the study didn’t change their behavior.

Researchers say their findings show dogs don’t make facial expression involuntarily, but rather as a way to communicate. Human attention also affected how vocal the dogs were, but not how much they sat or stood, which are considered their non-communicative behaviors. 24 family dogs were observed in quiet rooms. A video camera was placed in the room to record the dog’s faces.
