Four years later he helped to find people buried under rubble in the Nepali earthquake which killed almost 9000.
Diesel was named Animal of the Year in 2019 by the International Fund for Animal Welfare for his life-saving work, while having also been recognised for his contribution to both the SFRS and the UK ISAR team.
But now, a statement posted on social media has revealed Diesel’s death.
“Unfortunately, we have to announce that Diesel’s collar was removed for the last time today,” the SFRS’ post on Twitter said.
“He is at peace now but his memory will live on from what he has done for SFRS & UK ISAR. Stand down Diesel boy your work is done. Sleep well.”
His death has prompted a flurry of tributes online.
“Heartfelt sympathies to Gary and everyone who loved Diesel. They were an incredible partnership and outstanding ambassadors for SFRS. We were fortunate to work with them at an incident and witness the bond between them,” one said.
Another said: “Diesel was a truly fantastic servant and made a huge difference at so many jobs… R.I.P. pooch.”
After Diesel’s 2019 commendation, his handler Gary Carroll said it was a proud moment.
“I’ve had Diesel since he was a puppy and seen him progress into a fully qualified search dog,” he said at the time.
“We have a unique bond where he looks after me and I look after him.”
