I Had No Idea That Dogs Could Smile! LOOK At This Cute Baby!

It's usually easy to tell when dogs are happy – their tails wag, they get excitable, and sometimes they even run around the room. But this little chihuahua has another way to tell her owner that she's happy: A big bright smile that goes from ear to ear!

I'm not sure I've ever seen something cuter than this – A tiny little dog with the biggest grin. If you know someone who could use a smile today, please SHARE!
