Let's face it: Packaging sells. Beauty sells. Cuteness sells. And the 6 million to 8 million dogs and cats that land in shelters every year need something to help "sell" them to their potential owners. If you're scrolling through Petfinder looking for your new best friend, which dog are you more likely to click on? The one whose face is obscured by bars, or the one joyfully chewing on a stick? That's the power of a photograph — to get you to look twice, to fall in love, to change an animal's life.
