Hellhounds are supernatural dogs of exceptional strength and size and appear in the folklore of many different cultures, including Greek mythology and Central American folklore (known as a ‘cadejo’). Common features that are attributed to hellhounds include glowing red eyes, black matted fur, phantom-like characteristics, and a foul odor. Legends claim they are ushers of the afterlife and omens of death. Some stories say one sighting means death is near, while three sightings means death is imminent. Fluffy from the beloved Harry Potter series is one of the most well-known hellhounds in the modern age. Another famous hellhound is Cerberus, the hound of Hades that guards the gates of the Underworld. Many have claimed to see a hellhound roaming in Kentucky and West Virginia (named the Appalachian Hellhound), which is said to be a large, black dog-like creature that hunts in the mountains.
