Just try not to smile
March 23, a.k.a. National Puppy Day, was founded in 2006 by celebrity pet and home lifestyle expert Colleen Paige. (She’s also the founder of National Dog Day, which is August 31, and National Cat Day, which is October 29.) The holiday is meant to help save orphaned puppies across the globe and educate people about puppy mills.
To help you celebrate, we’ve compiled some of the cutest pictures of puppies on Instagram. A few are the pets of TIME 100 honorees, some are prominent Internet celebrities in their own right and others are from shelters across the world—in case you decide to get a new best friend after seeing all of these squishy faces, floppy ears and puppy-dog eyes.
