The last known rescue dog that served during the 9/11 attacks has died.
Bretagne was only a year old when she was sent into the rubble of the World Trade Centre buildings in New York in September 2001.
A few years later she was deployed to New Orleans in the wake of Hurricane Katrina.
Bretagne retired from search and rescue when she was 10, instead acting as a goodwill ambassador and reading assistance dog.
"Each week she would visit a first grade classroom and listen to young readers, providing a non-judgmental ear and soft paw," read a statement from the Cy-Fair Volunteer Fire Department based in Houston.
She was euthanised after suffering from declining health and kidney failure, but not before staff she worked with formed a wall of honour.
"She served her country. She served her community. And this is just a small way for us to honour her on her way out," firefighter David Padovan told local media.
"It's very hard. Bretagne's part of our family," said department chief Amy Ramon. "I've known her for her entire life and she's always been there. She's one of us. It's hard."
Bretagne visited the site of the New York attacks when she was 15.
Depending on which calculator you use, Bretagne was aged between 77 and 104 in human years when she died.
