To construct the four-legged protagonists of The Last Dogs, he draws on his recollections of Salt, Pepper, Cupcake, Ariel, Shadow, Brandy, Sir Edmund Spunk, and Showtime Double Double. He's done a variety of professions, including selling gum and gum machines, but he started writing professionally at the age of eighteen.
