Have you ever heard the blood-curdling howl of a dog in a foggy forest? What does your imagination draw about this? Personally, I imagine a huge black dog with tan marks, with huge teeth, powerful long paws and a bewitching gaze. It looks like a Doberman. They are very fast and strong, and are ready to drive their prey long and hard, so if you hear a howl in a foggy night, or the tramp of powerful paws through puddles, you know that you will no longer be able to escape Baskerville.
