The fiery red eyes and the blood-curdling howls of ghostly Black Dogs have long haunted the pages of British literature. From Arthur Conan Doyle’s The Hound of the Baskervilles to the sinister Padfoot in the tales of Harry Potter, time and again nailbiting stories have been woven around the legend of mythical huge dogs.

Now zoologists and experts in the paranormal are calling for a probe to prove their existence.
