Cave dogs

Cave dogs bare little resemblance to their canine counterparts.  Blind, hairless and with razor sharp teeth, they were designed to have a heightened sense of smell for dark environments.  Highly uncontrollable, Cave dogs were meant to be used for patrols of sewers and subways by Corporate, but instead many got loose and now roam the dark hidden corners deep beneath New York City.  Even Voids will make a wide berth of these creatures, doing their best to avoid them at all costs.
