Can animals smile? Or put on a happy face

How many faces do you show to the world? Happy, sad, surprised, scared, mad, excited? Yes, all those and more. We know what a happy smile looks like on the faces of our friends and families, but do animals smile?

Smiles on animals’ faces perhaps are just misconception we have made.
