Brave pooches that ate their dog food and slept on the site of the fallen Twin Towers ten years ago have been commemorated in special book.
Dutch photographer Charlotte Dumas has put together Retrieved, a book of portraits that focuses on the rescue dogs who helped save lives after 9/11, reports the Daily Mail.
Researching her book, Ms Dumas found that around 100 dogs were part of the first responders deployed by the Federal Emergency Management Agency.
Of the dogs who helped find survivors in the rubble, only 12 now survive.
Ms Dumas is quoted as saying: "I felt this was a turning point, especially for the dogs, who although are not forgotten, are not as prominent as the human stories involved
"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."
An exhibition of the photographer's work will be on show Julie Saul Gallery NYC from September 8th.
