A dog will stay stupid. That's why we love them so much. The entire time we know them, they're idiots. Think of your dog. Everytime you come home , he thinks it's amazing. He has no idea how you accomplish this every day. You walk in the door, the joy of this experience overwhelms him. He looks at you, and thinks, SHE'S BACK, IT'S THAT GAL, THAT SAME GAL. He can't believe it. Everything is amazing to your dog. ANOTHER CAN OF FOOD? I DON'T BELIEVE IT.
