Stone-age peoples shared graves with their dogs. Stone age communities in the Iberian Peninsula (today’s Spain) buried dogs alongside humans - mainly in circular graves, together or near humans. The burials may have been sacrificial or religious in nature - “found in an area of cultural influence that gives a symbolic value to the dog during that period.” These dogs were also fed a diet very similar to that of their owners and their proximity to their owners’ burial suggests the important role they played in the lives of Neolithic populations.
