I got the idea for that story in May of 1979. I didn't know what it was going to be; I just thought it would be neat to write something about Jack the Ripper's dog, and ask Gahan Wilson to illustrate it, partly because of the fact that a dog is such an unusual person. No matter who owns a dog, if that person is nice to the animal, the dog is going to love him. I thought at the time, if you take a really despicable person, a serial killer or someone like that, and tell a story from his dog's point of view it would make him look pretty good.
