I don't agree with giving a dog too much space to run around in when you want them to be calm or when you are out. My dogs know they have to sleep on the floor of our bedroom and not move apart from to get a drink of water. I think we either closed the bedroom door to start of with or we used a baby gate, can't quite remember. She'll prob just be happy to be in the room with you. With regards to the fire place - if she starts to get more intent about her staring, then distract her. Not good for a dog to get fixated, it can lead to other things. Best nip it in the bud by distracting her x
