Not sure how to tell what The Black Dog Dialogues is about, lol! It was supposed to be a short story, at most, a novella, to go in an anthology with that title, a series of stories loosely tied together by the different Black Dog legends that have been told since -- well, since we started telling stories -- but it's taken on a life of its own. I'll probably still do an anthology, but this one's going to stand alone, looks like.
The Black Dog legend that appears in it is a modern one, from long haul truck driver stories. It's a phenomena, and appears when a driver is exhausted and starts to hallucinate. Weirdly, the majority of the hallucinations are black dogs. Sometimes guys will see something different (one guy's "black dog" was a baby in a briefcase), but it seems to be rare that, after a driver experiences his Black Dog, it ever changes. He'll experience the same vision -- or visitation -- whatever it is -- each time.
