Did you know that dogs can change faces when they know you are looking at them? It could be a try at communicating with you!

During the study, it was observed that when a dog looked into a human’s eyes they would lift their inner eyebrows which made their eyes look bigger and more innocent. This face is also known as a “sad puppy dog face.”

Dogs are always monitoring people according to research. They watch how we move, the gestures we make and look at our faces. Domesticated dogs do this more than even wolf puppies that have been raised by hand by people.

“Dogs read human gestures and communicative signals in ways other animals can’t,” investigator Juliane Kaminski, a psychologist at the U.K.’s University of Portsmouth stated.
