Something Trying To Get In Or Out Or More?

I was sitting at the computer in the play room and the girls were in the living room watching tv and playing on phone and we heard from the kitchen someone or something kicking or pounding on the back door forcefully. It was loud, even had our dog barking and running to see what it was. We thought maybe it was Nathaniel coming home, but checked and nothing around at all. Also, this gave you that kind of shiver throughout your body when it occured.
