While trolls themselves have had great success in domesticating, training, and even befriending trollhounds, the same cannot be said for other would-be masters. Whether impeded by constant exposure to trollhounds' diseased slobber, their ravenous hunger that never seems to be fully sated, or simply their foul personality and quick-to-bite temperament, most attempts to use trollhounds in place of more reliable guardians end in pain, misery, and a pack of feral trollhounds escaping into the hinterlands. Left to their own devices, a pack of escaped trollhounds can breed relatively quickly, and it can take less than a year for a small pack to multiply into a significant threat to the countryside. Best to leave the trollhounds to the trolls, as they say!
