Friday is National Dog Day, an annual observance with the goal of honoring your pups and spreading awareness about rescue dogs. Started by pet expert Colleen Paige, National Dog Day is held every year on Aug. 26 — the anniversary of the day she adopted her first canine.

It's a chance to donate to your local shelter, volunteer with animals or simply cuddle up to your furry friend. If you're stuck at work, though, you can still celebrate with these adorable puppy photos and great quotes, collected from Goodreads, DogTipper and DogTime:
