MailOnline - During the chaos of the 9/11 attacks, where almost 3,000 people died, nearly 100 loyal search and rescue dogs and their brave owners scoured Ground Zero for survivors.
Now, ten years on, just 12 of these heroic canines survive, and they have been commemorated in a touching series of portraits entitled 'Retrieved'.
Travelling across nine states in the U.S. from Texas to Maryland, Dutch photographer Charlotte Dumas, 34, captured the remaining dogs in their twilight years in their homes where they still live with their handlers, a full decade on from 9/11.
Contacting the NYPD, the New York Fire Department and the Federal Emergency Management Agency, Charlotte discovered that out of the nearly 100 dogs among the first responders deployed by FEMA, there were in fact only 15 still alive last year.
"The dogs are now old and they will soon pass away. Even during the time it has taken since my first work on the 'Retrieved' portraits to now, three of the final 15 have died," said Charlotte.
"These portraits are about how time passes, and how these dogs and their portraits are offering us a way to deal with the things that happened as well as relying on them for comfort."
