Natural histories: Dog

BBC Radio 4

Krithika appears in this BBC programme about the impact of dogs on humans and vice versa. Brett Westwood visits Battersea to meet the animals whose history is most inextricably linked with our own. As the first domestic animals, dogs made it possible for humans to spread into the areas of the world that they did, to eat more protein and to take up activities from hunting to sledding. But it was only in the Victorian period that the dogs we know today were "invented", by breeding. And throughout all of this dogs have also been changing human lives as companions.
