Book excerpt: Illustrated stories about dogs that knew how to sit, stay, and witness history—from the loyal Greyfriars Bobby to Lizzie Borden’s Boston Terriers. Most dog lovers know Fido and Laika, but how about Martha, Paul McCartney’s Old English Sheepdog? Or Peritas, Alexander the Great’s trusted canine companion? As long as there have been humans, those humans have had beloved companions—their dogs. From the ancient Egyptians mummifying their pups, to the Indian legend of the king who refused to enter the afterlife unless his dog was allowed there too, to the modern meme and popularity of terms like the corgi sploot, humans are undeniably obsessed with their dogs. Told in short, illustrated essays that are interspersed with both historical and canine factoids, The History of the World in Fifty Dogs brings to life some of history’s most memorable moments through the stories of the dogs that saw them happen.
