This would be one of the reasons I LOVE dogs. There is nothing better in life than a happy pooch.

I love when I walk in the door and our family dogs Bailey and Jet or my dog Blue go absolutely crazy! They grab their toys and come running back to show me, they wag their tails and end up whipping you in the leg with them and they look like they are smiling at me. In fact, I'm sure they are smiling.

This dog certainly is.

Chii is a Shiba Inu who resides in Japan and she really  does smile, but she only smiles for her owner! One of the best youtube videos I've ever seen, this is your pick me up on hump day:
