With this September/October issue, Bark strikes gold! To celebrate hitting 50 (issues, that is), we set a lavish table, loaded delights for both the mind and the eye. In the triple-article feature “Genealogy,” we look at the ways DNA testing attempts to unscramble the genetic secrets of well-mixed pups. Dogs of the Mississippi Delta are also on tap, captured by renowned photographer Maude Schuyler Clay. The irrepressible Martha, star of Susan Meddaugh’s classic children’s stories, Martha Speaks, debuts on PBS, and we score an in-depth interview with the creators of the series. Well-versed vet Nancy Kay tells us how to speak up for our dogs, and just in time for Halloween, we show you how to sculpt a pup-kin or stitch up a costume for your pooch.
