It’s always a heartbreaking sight to see a forlorn dog peering out of a car, windows up, no owner in sight. UK photographer, Martin Usborne, whose photographic career began after a number of years working as a creative director in children’s TV, has created a melancholy series of photos entitled Mute: The Silence of Dogs in Cars - a little nod to all those quiet dogs out there, sadly waiting for their owner to return.
