From the vault: On September 11, 2001, pup Roselle guides blind handler Michael out of the Twin Towers

On September 11, 2001, Michael was working on the 78th floor of one of the Twin Towers, with his guide dog Roselle by his side as always. Since Michael is blind, his best friend Roselle constantly acted as his eyes. When the planes hit the Towers, Roselle and Michael had to work as a team to get down 78 flights of stairs and out of the path of danger.
