If there is mud, there will be a Golden Retriever

There are few certainties in life, but even at a young age I've discovered that if there is dirt you will find Belle or if there is a tennis ball, it will be in Belle's mouth. As this photo proves, if there is dirt and a tennis ball, Belle will be on it with the ball in her mouth. Dogs are so predictable. Now if only I could figure out how to play in the mud without moving Belle.
