All my dogs so far have been obsessed with fireplaces, when the fire is lit. It goes so far that they don't sleep at night, they keep hopping up and down next to the fireplace. When I put their sleeping pillow next to the fireplace, no matter how often I call them to sleep on it, they just don't. They have to be excited about the fireplace. The dogs only sleep if they are far, far away from the fireplace or when the fire is out. This really bothers me, as I want my dogs to sleep close to my people and I don't want to put out the fire each night so that the dog sleeps.
