our crazy dog

We have a strange dog. Willow is a 4-year-old mutt. She has some Chesapeake Bay Retriever, possibly some pit bull, and who knows what else. Four years ago, our kids prayed like crazy and saved their pennies, and we finally found Willow. We love her dearly, but there is one little thing she does that makes us wonder about her. You see, a couple years ago, she discovered our ficus tree in our master bedroom. At least once a day, often more, she, well.... You'll just have to watch the video. If anyone has an explanation for us, it would solve a great mystery in our home. "What in the world is that dog doing??"
