4,000 years ago: Ancient dogs enter human literature

The experts at Alaska Dog Works share this moment in dog history: 

Long before “Clifford the Big Red Dog,” there was “The Show Dog” and “Why the Dog is Subservient to Man.” These two ancient tablet-based texts were written around 2000 B.C., long before “Aesop’s Fables” made dogs a common subject of literature. Once again, early dog lovers had the Sumerians to thank.
