Photographer Charlotte Dumas' photo series 'Retrieved' captures 15 rescue dogs that helped search for and recover victims from the rubble of the former World Trade Center and the Pentagon following the 9/11 terrorist attacks.
Despite being playful and spirited like most dogs, the canines in these photos are depicted as displaying the weight of their histories. Their limbs stand at attention as if they are military personnel, and their noses sniff and whiskers perk up as if to convey a state of permanent alertness.
As the dogs grow visibly older, the passage of time makes itself felt on their features. Charlotte Dumas captured these incredibly loving and intelligent animals to catalog their heroic feats, and also to serve as a reminder of the tragic events of 9/11.
