Pickman's Model

Well, IIRC the model was a tunnelling intelligent ghoul-dog which was large and blasphemously evil (of course). My initial thoughts would be wererat or werewolf, or possibly a ghoul variant. Nothing really seems like a close fit though.

Here is a suggestion, sort of a combined werewolf/ghoul except that it doesn't shapechange. Any comments or suggestions?

These creatures eat flesh, whether living or dead. They are evilly intelligent and delight in torture and slaughter. Normally they live in a network of tunnels beneath a city; the maze-like network will have many exits and usually connects to a graveyard. The creatures only come out at night to kidnap victims for their bloody rituals and moonlight feasts. They exude an aura of evil and dread which causes temporary paralysation in their victims. If both claw attacks hit, the creature automatically bites!
