Enterprise has an office dog. She’s a baladi dog, mostly black but with a patch of tan on her chest. Sweet-natured, she lives in the garden of our office building. We feed her and lavish her attention on her (as do our corporate neighbors, good-hearted souls that they are) and in return protects us from scoundrels, youts, and random passers-by on bikes. Her name is Rita, though one editor’s daughter insists “Diego” is a much more appropriate name. Like the hundreds of others what inhabit the streets of Maadi, Rita / Diego and 750 mn other street / village / free-breeding dogs around the world are “the closest living things to the dogs that first emerged thousands of years ago.” The New York Times profiles a couple whose research on street dogs has turned on its head everything we thought we knew about the evolution of Man’s Best Friend.
