The Black Dog is a legendary demon hound. Folklore has it that if you see this phantom dog with a black coat and blazing eyes (or horrible empty pits) bad luck or even death is close at hand. This huge dog has demonic red eyes, and it appears only at night, terrifying lone travelers. It is said that you will feel an unnatural chill before you see it appear. Tales of black dogs are especially rife in Britain, though some experts think Viking raiders brought these stories with them from Scandinavia. The dogs are often linked with churches. A black dog that visited the church of Blythburgh in Suffolk in 1577 killed three people. Black dog stories influenced Arthur Conan Doyle when he wrote his Sherlock Holmes story, The Hound of the Baskervilles.
