Mmmmyyeezzzzz. But...was “The Hound” created early on to aid in the de-fanging, or later to preserve it?
Not specified, but I'm going to go with later based on the narrative that was provided.
Side note, apparently Ray Bradbury didn't have much in the way of ready cash or assets when he wrote Farenheit 451 so he wrote the entire thing on a library typewriter for which he paid by the hour. I think it was some exorbitant sum like $.10.hour. Anyway, that's why it is such a minimalist story.
