You slowly back off, but the dog leaps toward you. Incredibly, it leaps past you and out the cave.
You turn around to spot it battling with a hideous black animal that somewhat resembles a wolf. Sludge hangs from its skin. It runs on four powerful legs with claws longer than your entire hand. Standing on four legs, it is slightly taller than you and had no jaws. Instead, there is a round closing-and-opening mouth filled with jagged teeth. Two bulging eyes seem to have been just stuck onto the sides of its head.
You have to get past it.
