A veterinarian for 25 years and operator of Indianapolis's Broad Ripple Animal Clinic for 22 years, Dr. David Brunner specializes in treating small animals--cats and dogs. He has two daughters, Molly and Kendell, and two black Labrador retrievers, Lucy and Noel, both of whom come to work with him every day. Sam Stall is the coauthor of As Seen On TV: 50 Amazing Products and the Commercials That Made Them Famous and Dirty Words of Wisdom . He resides in Indianapolis with his three terrier mixed-breeds, Tippy, Katie, and Gracie, as well as his wife, Jami (who has no terrier blood whatsoever), and their cat, Ted. Paul Kepple and Jude Buffum are better known as the Philadelphia-based studio Headcase Design. Their work has been featured in many design and illustration publications, such as American Illustration , C ommunication Arts , and Print . Paul worked at Running Press Book Publishers for several years before opening Headcase in 1998.

Both graduated from the Tyler School of Art, where they now teach. While illustrating this book, Jude acquired a Boston terrier named Huxley, which he has since programmed to sit, stay, roll over, and mix cocktails. Paul's dog, an imaginary Jack Russell named Crackers, was last seen romancing a pair of running shoes.
