I've always thought mysteries with cat protagonists were silly, so I was surprised at how much I enjoyed Dog On It. The narrator, Chet, is a mixed breed dog. Quinn does a wonderful job at getting inside his doggie mind, at least at what we humans imagine to be in there.
At one point in the story they go off to Las Vegas which Bernie (the human private detective) refers to as the "ninth circle." Chet sees The Strip as "a broad avenue lined with weird buildings, weird lights, weird people, weird everything."
