The Pounding And Crying/Whining

We heard some very loud and persistant pounding coming from somewhere within the house. We couldn't find out where it was coming from and it happened a few times before it eventually stopped. Not long after it stopped, coming from the dingroom area there was something that sounded like a cry or dog wimpering, but when I went out there to see what it was and where exactly is was coming from, it stopped.
