A truly heroic lab, Roselle the Labrador was a guide dog who saved her owner and numerous other business people when they became trapped on the seventy-eighth floor of the North Tower of the Twin Towers, during their collapse on September 11th 2001. While everyone around him panicked, owner Michael Hingson, blind since birth, was kept calm by his guide dog Roselle, who led him down the staircases of the collapsing building. As they descended the stairs, they gathered more and more panicked people who ultimately followed the Labrador to safety. The descent took approximately an hour.
