It could be that your dog hears something (another dog, a certain car or truck especially one that sound like a the mail man or a delivery truck) which he considers a threat. It could even be a cat prowling around. I would do what you are doing - get up and check, but I would make sure to stand in front of the dog to show him that I am in control of whatever is out there. Even open the door and look outside. Then I would yawn (a calming signal) close the door, and walk away like it is no big deal.
