"Demon Dog" is only one of many names used to describe ethereal, black dogs that roam hillsides and graveyards. With their glowing red eyes, super strength and speed, and a tendency to trail fire and brimstone in their wake, Demon Dog make for a terrifying messenger from the underworld.
They are said to have been created by a group of ancient demons to serve as heralds of death, and seeing a Demon Dog — some say once and others claim it takes three sightings — inevitably leads to the viewer'sdemise.
Demo Dogs boast many titles, including Black Shuck, Hellhound, Cerberus, Garm, and Perro Negro. In the popular Harry Potter series, author J.K. Rowling referred to a menacing Hellhound as "The Grim."
Demon Dog legends date back to the time of Vikings and sightings have been reported throughout history.
These sightings, which are not confined to one region of the world, have more recently occurred near cemeteries in Connecticut, Kentucky, Louisiana and Ohio.
