There’s a free Purina One SmartBlend dog food offer available today. I was a bit fixated on the two questions at the very end though. How is “CAUSE IT’S FREE!” not a possible answer for what interests me most about Purina One? And I laughed pretty hard at “do you have a photo of your dog that shows his true instinct?” Nope. I don’t keep many photos around of her licking her butt.
