3D model, medium-sized fantasy beast, Crag Hound. Creature has a lean, athletic wolf-like anatomy with visibly powerful jaws. Fur should be a mottled grey-brown, appearing thick, somewhat shaggy, and coarse. Features include unnervingly intelligent, perhaps faintly glowing, yellow eyes and a snarling muzzle with bared teeth. The model should emphasize lean muscle definition beneath the fur, conveying agility and ferocity. Overall style: realistic canine features but with a more savage, monstrous edge suitable for a gritty low-fantasy setting. Natural, slightly desaturated earth tones for fur.
