Trophic Dynamics by Gabrielle Bleu

Sixteen dogs used to roam the back streets in a howling, violent mass. Until one day when their numbers began to dwindle; thirteen, seven, four. Until all that remained were two mangy survivors, tails between their legs. People were happy that the back alleys were safer, not questioning the disappearances. Only one girl wondered, and only after she saw the footprints, large and clawed and numerous.

Only she saw, as the thing with too many legs grew bolder, emerging from the shadows. Only she watched from her window late at night, as it ate the dog pack down to one.
