Hell hounds are fire-breathing canines from another plane of
existence brought here in the service of evil beings. A hell
hound resembles a large hound with rust-red or red-brown fur,
and red, glowing eyes. The markings, teeth, and tongue are
soot black. It stands two to three feet high at the shoulder
and has a distinct odour of smoke and sulphur. The baying
sounds it makes have an eerie, hollow tone that sends a shiver
through any who hear them.
