Porter attack

Porter loves playing with the girls.  He follows them all over the house and most of the time he is fast enough to keep up with them.  But sometimes the girls get a headstart and this is what happens. . . I wasn't fast enough with the camera, but just before I got there he was laying on the floor trying to peak under the door.  Just behind the door came squeals of delight from the girls, "Don't let him in he'll attack us!"
