Mister Dillon or D was Troop D's police dog and was present when the Buick Roadmaster was brought in. The dog would be present at several of the lightquakes and just like Curtis Wilcox had a bad feeling about the Buick. He would howl and whine whenever he was around the Buick. He would later be present at the killing of the thinking being and would accidentally ingest some of its acidic blood after biting into its flesh. The blood started burning Dillon's insides and it was apparent he was in serious pain. George Morgan then shot Dillon to put him out of his misery.
