The Dogs is a short story written by Jeffrey Thomas. It was first published in the 2014 anthology The Dark Rites of Cthulhu, edited by Brian M. Sammons.
Description[]
A lonely man uses his library of esoteric books to create a device which allows him to peer into the Earth's future. What he sees is a planet ravaged by the arrival of enormous floating abominations who have wiped out the human race.
As he looks farther ahead, he sees the descendants of Earth's dogs as they slowly evolve into something more intelligent, before devising a way to escape the planet as the Outsiders descend from the sky to render it completely uninhabitable.
