We Dare You NOT Yawn When You See These Adorable Animals!

Pugs, polar bears, and puppies, oh my!

These super sleepy animals can't stop yawning, and we can't stop staring, because they're just WAY too cute for words. A yawn is a reflex in which air is inhaled and the eardrums stretch, followed by an exhalation. Animals (and people) yawn due to a number of reasons, including tiredness, boredom, or overwork.

What makes you yawn? Please SHARE these lovable yawning animals with your friends and just DARE them not to yawn!
