This dog absolutely loves peanut butter, or beurre d'arachide as we have learned to call it. Even the Wal-Mart brand will do, he's not picky. Friends and neighbors know to drop off their empty jars at our house as a treat for Duke. It makes him very, very, happy. And it makes me happy because it occupies him for at least an hour. Are we talking about a toddler or a dog? Some days I wonder.
