Show your four-legged friend a little bit of extra love, because it's National Puppy Day.

Yup, it's a real thing. In fact, according to the National Puppy Day website, Puppy Day, which occurs annually on March 23 is now considered a national holiday. Colleen Paige—pet and family lifestyle expert, animal behaviorist, and author of The Good Behavior Book for Dogs—founded national Puppy Day in 2006 in an effort to educate people about puppy mills and encourage them to adopt. 

So, if you've thinking about getting a dog, here's your sign. If you already have a pup, show him (or her) your appreciation by getting outside for a run. Be sure to follow these 9 tips for running with your dog. Or, if you can't handle that responsibility, there's sure to be no shortage of adorable puppy vids circulating the interwebs today if that's how you should choose to celebrate. 

Happy #NationalPuppyDay, everyone.
