Hellhounds:

Hellhounds are a lesser-known type of supernatural entity. There are no confirmed visual evidence of them, leading to speculation that they may be invisible, or they are too swift to be caught. Some theorize that they don't exist at all. Though, evidence suggest the existence of these demons by grisly 'invisible' violent dog attacks.

Habitat:

Unknown

Method of Killing:

Hellhounds kill just like a regular dog would, typically using their sharp claws and teeth to rip into their victims.

Weaknesses:

Salt circles are believed to temporarily stop a Hellhound from getting near, although the truth of this remains uncertain. The ways of ending a hell dogs life is unknown.
