Last known surviving 9/11 search and rescue dog laid to rest

Firefighters and rescue workers lined the sidewalk as her body, draped in an American flag, was carried out. Tears streaked down some faces.

Bretagne, believed to be the last surviving 9/11 Ground Zero search dogs, was euthanized Monday.

The golden retriever was 16. Old age had slowed her down, and it was time to put her to sleep.

So, the firefighters at the Cy-Fair Fire Department in Harris County, Texas, lined the path up to the Fairfield Animal Hospital, as her owner, Denise Corliss, walked her in to be put to sleep.
