Prehistoric people may well have had an emotional bond with domesticated dogs much earlier than we thought. Leiden Ph.D. candidate and vet Luc Janssens discovered that a dog found at the start of the last century in a grave dating back 14,000 years had been sick for a long time and had been cared for.
