What do you have in your mouth Harper?

As soon as I walked in the house I knew he did something wrong he usually greets me at the door but this time he was on the top of the stairs looking and me laying down just thumping his tail on the ground. He actually is a very very good dog he is only a year and a half old.I felt bad but he will not even go near them anymore ... Excellent dog very very friendly and loves people.
