A heroic fire investigation dog, who played a crucial role in the Grenfell Tower fire response, has retired after 12 years of dedicated service with the London Fire Brigade (LFB).
Sherlock, a working cocker spaniel, joined the brigade at just 10 weeks old and went on to become their longest-serving fire investigation dog. Over his career, he assisted in countless fire investigations, detecting ignitable substances to help determine the causes of fires across London.

Sherlock’s Role in Fire Investigations
Sherlock was trained to detect up to 10 different ignitable liquids, including petrol and acetone, which helped investigators identify arson cases and determine how fires started.
One of his most notable assignments was the Grenfell Tower fire in 2017, where he worked tirelessly with fire crews to examine the aftermath of one of Britain’s worst residential fires.
His expertise was also instrumental in several other major incidents, ensuring arsonists were brought to justice and helping the London Fire Brigade promote fire safety.

A Well-Earned Retirement
Sherlock’s handler, Group Commander Paul Osborne, praised the dog’s dedication and unwavering service, saying:
“In dog years, Sherlock is 100 years old, so it’s only fitting for him to hang up his boots now and take a well-earned break.
“He’ll enjoy a relaxed retirement filled with naps on the sofa, his favourite walks, and plenty of belly rubs.
“As Sherlock embarks on this new chapter of his life, his contributions to fire investigation and public safety will never be forgotten.”
A Special Dog for a Special Role
The London Fire Brigade carefully selects its fire investigation dogs based on high energy levels, motivation, and a strong work ethic. Sherlock was chosen due to his keen sense of smell and drive to work, making him an ideal fit for the job.
He was trained using a tennis ball as a reward, a technique that kept him engaged and eager to locate fire accelerants. While most fire investigation dogs serve for around 10 years, Sherlock continued for an extra two years, showcasing his exceptional abilities.
Legacy and New Recruits
Sherlock leaves behind a remarkable legacy, and his retirement makes way for the next generation of fire investigation dogs. The London Fire Brigade’s current fire dogs, Simba (8) and Smokey (3), will now take on his vital responsibilities.
His career has been a testament to the incredible role that dogs play in fire investigations, and his retirement will see him enjoying the simple pleasures of being a beloved pet.
