Dogs! Who knows?

Today my dog diamond has shown a fascination with our electric fire place. Usually she will just sit by it, loving the heat being so close to her. Today however she has not only sat next to it but has stared at the flicking fire most of the day. At moments during the day I have found myself wondering what she is thinking about sitting there. I wonder do dogs find staring at the glow of the fire as soothing as we do?
