My bedroom is at the end of the hallway. I'm not trained to clear houses, and the other end of the hallway is shaped light a doughnut (kitchen, dining, living room all in a circle with one wall in the middle. Two doorways I can get shot from, so I'm not comfortable moving down the hallway.
As far as the dog is concerned, I was thinking it would be a two pronged attack. The dog and I would both go down the hall to attack, probably ending in a dead or wounded BG, but also possibly a dead or wounded dog.
I'm thinking staying at the doorway of the bedroom is my best bet. I don't like the idea of keeping the door to the bedroom closed. I can't see anything outside the room, and thus can't locate the BG. It's more a sense of helplessness.
