Flo. 'This is the photographer Martin Usborne's earliest memory: "Being left in the car, and this feeling that no one would ever come back . . . the impossible loneliness of this silent space."' Photograph: Martin Usborne

Bones. 'Usborne spent many days wandering around supermarket car parks, barking ("I was looking for dogs but I couldn't see any. I thought they must be all lying down"). Then he realised that people actually didn't leave their dogs in cars that often.' Photograph: Martin Usborne

Peggy. 'There was nothing for it but to find particular dogs, and then put them in cars.' Photograph: Martin Usborne

Bones. 'Many more hours were spent matching the expression of the dog to the type and colour of the car. Much ham was wasted.' Photograph: Martin Usborne
