Bretagne, a 16-year-old golden retriever and the last known remaining Sept. 11 search dog, was euthanized Monday in Texas.
Searching through the rubble of ground zero was her first-ever deployment, according to a press release by the Texas Engineering Extension Service, or TEEX, provided by KBTX-TV. Bretagne (pronounced Brit-nee) was 2 at the time, a newly certified FEMA Search and Rescue dog.
With handler Denise Corliss, Bretagne looked first for survivors, then for remains. They worked at the site for 10 days.
Bretagne was both a dedicated worker and a source of comfort for the human search and rescue teams, according to Corliss and others who worked with the golden retriever.
