…to pull at our heartstrings. Canines know how to alter their facial expressions to manipulate human emotions. Researchers from the University of Portsmouth (UK) investigated whether dog’s facial expressions were tailored to attention from people. Dogs really do put on their puppy eyes to pull on our emotional heartstrings, new research has found.
Experts found that pet pooches raise their brows when they are being looked at, making their eyes look bigger, as well as pulling a number of other expressions. Our manipulative four legged friends do not respond with more facial expressions upon seeing tasty food, however. This suggests that they change facial expressions to communicate and not just because they are excited.
