Read carefully, and two different bellcurvey elements present:
(1) Dinduistands are notorious for packs of dogs running around; the dogs are former pets that the owners jettisoned or just let drift free. The dogs meet each other and form packs. And they’re even more dangerous packs than the typical dogs, because dogs that black people own tend to be vicious breeds, pit bulls among others.
(2) Dinduistans are also notorious for unkempt cemeteries and memorials. You can tell if a cemetery you’re passing by is a black one if the grass is overgrown.
Of course, those aren’t the only two bellcurvey elements of this narrative.
