If you've ever had...or seen... a pet dog, maybe you've noticed how they "raise their eyebrows" at you all the time. Turns out, dogs weren't always able to do that! Researchers compared the muscle structure between wolves and domesticated dogs and our sweet pets have the ability to raise their eyebrows while wolves don't. This movement makes their eyes appear bigger and therefore more infant like, which causes humans to form an emotional connection with them. I have two dogs at home and they are constantly making this face at my husband and I, and watching this video makes me want to go home and cuddle them immediately! Check it out in the tweet below to see everything, and scroll down for an example from my sweet babies!!
