"Ludo is a dog--Simon Garfield's beloved black Labrador retriever, one of millions of canines who have become integral parts of our lives. But how did the dog become top dog? How did these faithful animals come to assist us not only in hunting, but in bomb disposal and cancer detection--and ultimately become our closest companions? Dog's Best Friend examines how this bond developed over the centuries, and how it has transformed countless lives, both human and canine. Garfield begins with the earliest visual representations--dogs depicted in ancient rock art--and ends at the laboratory that first sequenced the canine genome. Along the way, we meet the legendary Corgis of Buckingham Palace, the dogs of the Soviet space program, the world's first labradoodle, and a border collie that can identify more than a thousand different plush toys. Garfield reveals the secrets of the world's best dog trainers, takes us inside the wild world of dog breeding and dog shows, and unearths the deep psychological roots of the human-dog link. And Ludo pops his snout in from time to time as well."--Amazon.
