Tyrg
From Ardrana
The tyrg is a cross between a dog (in watchfulness) and a tiger (in stalking ability). A tyrg stands three feet tall at the shoulder and varies in length from six to nine feet. Its overall coloring is white with gray, black, and tan splotches. The tyrg's sleek stance while hunting is reminiscent of a cat, but its powerful jaws, containing many fangs, demonstrates its relation to the world's dogs. When tyrgs engage prey in melee, they emit fierce howls that serve to mildly stun their victims.
Note: Tyrgs originally appeared in this form in the Greyhawk Monstrous Compendium Appendix for the AD&D game from TSR. Their use here is for the purposes of providing context for the campaign only.
