Combat:
Death dogs are vicious predators.  On an attack roll of a natural 19 or 20, they have knocked down their prey.  They tend to attack humans on sight.

Disease: After every successful bite attack, the victim must pass a Fort save (DC 11) or succumb to a rotting disease which will kill in 4d6 days.  Only a cure disease spell can save the victim of the disease.

Society:
