WATCH: Puppy Power at Its Best

Even at a testosterone-filled gym, little dogs are disarming mood liftersIs someone you know having a bad day? Anybody feeling bored? Show up with a puppy. Surprise visits from little canines seem to transform people’s moods in a matter of seconds. This video is a demonstration of that. It was created to coincide with the release of Purina’s new dog food made without artificial flavors, colors or  preservatives. Purina will donate a pound (and up to 500,000 pounds) of its Puppy Chow Natural to Rescue Bank, a charity that distributes pet food to animal shelters, each time somebody views the video. Even if you’re not a “dog person,” you’ve got to admit these puppies light up the room, whether it’s a retirement home or a gym.
