Did you guys know that last week was National Smile Week?! Well, we did, and we know that it might be a new week, but we can’t resist a good smile! There’s just something about them that makes us so happy. So, in honor of this beautiful week, we rounded up 10 photos of cute animals showing off their grins. And as much as we love a good human smile, an animal one is even better! Check them out in the gallery below!
