Bretagne, the last known 9/11 search and rescue dog, was laid to rest. Firefighters lined up along a Houston area sidewalk to honor the canine as she took her final steps. Bretagne served our nation from trying to find survivors at the World Trade Center buildings to searching for victims during Hurricane Katrina. After Bretagne retired at 10, she became a member of a local Texas fire department. Bretagne was 16-years-old.
