Ghouls (Cthulhu Mythos)

Ghouls are creatures that were once human, having transformed after turning to an exclusive diet of dead human flesh. Their primary distinguishing feature are their dog-like snouts and hoofed feet. Ghouls are generally found beneath graveyards, and there is also a sizable population in the Dreamlands.

Ghouls are not hostile to humans who take care to be respectful, but those who enter their domain unbidden may not fare so well. However, a new faction of ghouls have appeared in some urban regions who kill living humans to eat them later; these ghouls are considered renegades by the more traditional, grave-robbing kind.
