This is the last surviving rescue dog from 9/11, sitting at Ground Zero. She was 2 years old during 9/11 and is 15 years old pictured
The rescue dogs at ground zero were upset and agitated by their failure to find survivors. Volunteers hid in the rubble so the dogs could find them.
This raised the dogs spirits and allowed them to continue their efforts.
By the way, have you considered that it might be armour for a war elephant?
