Many of these dogs seem to be hopefully and inquisitively saying, "Are you my master/human?" a bit like the child in that Doctor Who episode ("The Empty Child", I think) that kept saying, "Are you my mummy?". Some of the dogs in the photos, however, seem to be saying "You keep away. I don't need you. If you are my master/human you abused me so much that I no longer want anything to do with you. Never again." sweet juniper!
