This totally blew my mind. We took Willy out to go potty, and he felt like running. So he tore off running like a mad man and all of a sudden came running up the steps and decided it was a good idea to take a leap and blow through the screen on the screen door. I was mad because he completely destroyed the frame and all, but how can you stay mad at something that funny. I hope you all find this a humorous as I did. Maybe he'll learn to slow down as he approaches the porch from now on.
