A boy's best friend

So I'm kind of embarrassed that I'm putting this picture up. But Yes, my back door is really this dirty. The reason I took this picture though is because Cooper and Chalupa love to go in the backyard together. Cooper goes on the side of our house where it's still dirt and digs all day long. Chalupa sits next to him and digs too. I was cleaning the kitchen one morning and I heard a knock at my door and this is what I saw. They were done playing and wanted to come in. So cute.
