Peanut butter is one of the world's most wonderful foods. Its delectable nuttiness lingers long after you take your first taste. No one knows this truth better than dogs do. Dogs, more so than any human peanut butter devotee, appreciate the food for its simplicity. And they're willing to work for it.
They may not be able to craft a sandwich, but dogs knows there's nothing wrong with eating PB straight from a spoon.
