And then people started seeing dog skeletons walking around at night. First there were reports of single skeletons, and then packs of ghastly animated skeletal dogs. No one believed the reports at first, but then the sightings were reported nationwide. Each skeleton walking in its own unique way, a permanent toothy snarl on each skull, heads down, as if the habit of sniffing persisted in ghoulish phantasms with no possible olfactory sense. The empty eye sockets were wide and expressionless.
Occasionally a dog collar was spotted, dangling off a short span of spinal chord between the skull and shoulders.
At first people were alarmed, claiming it was a portent of the "end times," but biblical scholars had to admit that packs of dog skeletons fit into no known prophetic writings, old testament or new. Others conjectured that it was pollution, or radiation, but scientists had to admit they to could find no explanation.
As they passed through the streets at night, the dry, fleshless paws sounded like dry leaves skittering across the pavement, wind or no wind.
Motorists would see them crossing the street. Some would stop and watch the horrifying parade of dog skeletons cross the headlight beams, while others would hit the gas, scattering the bones everywhere, the satisfying crunch of bones sometimes costing them a chipped windshield if a particularly large skull impacted the glass. Later no bones would be found, as the skeletons, animated by some unknown supernatural force, would recombine and continue on toward whatever mysterious destination draws packs of dog skeletons.
