This Happiest Animals In The World Will Make Your Day Better

We know what a happy smile looks like on the faces of our friends and families, but do our animals smile?

Until recently, most animal behaviorists believed that an animal’s use of what we call a smile is no more than a collection of conditioned reflexes that move the muscles in the face. But new thinking on the subject is now allowing for the possibility that animals are expressing happiness when they “smile.”

In fact several new theories go so far as to attribute primary emotions like fear, sadness, anger and happiness – and even some secondary emotions like jealousy and embarrassment – to animals.

These photos of animals that look like they’re smiling are bound to warm even the stone-cold hearts among us.
