Paranormal activity in my home--Dogs behavior is making us think its messing with him!!

My Dog Louie turns into a demon dog when we are gone..I think whatever is is my home is scarring him to death when were gone. He was fine when I first got him, and at the time, I had just moved down here from Maryland and was staying with my Sister Patty, and he never acted this way at all....as you watch this video, you will see what looks like a "entity" walk in front of the camera.....
