The Last Dog Scout.

“You’d see firefighters sitting there, unanimated, stone-faced, no emotion, and then they’d see a dog and break out into a smile,” Otto recalled. “Those dogs brought the power of hope. They removed the gloom for just an instant — and that was huge because it was a pretty dismal place to be.”

Thirteen years after a dark day, 15-year-old Bretagne, one of the last surviving 9/11 search dogs, returns to Ground Zero. “In the years that followed 9/11, Bretagne and Corliss deployed together to numerous disaster sites, including Hurricane Katrina, Hurricane Rita and Hurricane Ivan. Bretagne retired from formal search work at age 9 — but today, even though she’s roughly 93 in human years, she still loves to work.”
