Sherlock, a fire investigation dog who served with the London Fire Brigade (LFB) for 12 years and attended the Grenfell Tower fire, has retired. The working cocker spaniel, born in 2012, joined the LFB at just 10 weeks old and became their longest-serving fire investigation dog.

       Sherlock was trained to detect up to 10 ignitable liquids like acetone and petrol, and also worked on promoting fire safety and prevention in the community. The heroic canine attended the Grenfell Tower fire in 2017 among other incidents, met royalty, and won an Animal Hero Award.

       His retirement will be filled with walks, belly rubs, and plenty of rest with his handler, Group Commander Paul Osborne. Mr Osborne said: "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 contribution and achievements during his time within London Fire Brigade are testament to his dedication, expertise and unwavering service."

       The LFB selects specialist fire investigation dogs based on their drive to play.

       They currently have two such dogs: Simba, eight, and Smokey, three. Sherlock was trained to detect ignitable substances using a tennis ball as a reward.

       Those who qualify as a fire investigation dog usually enjoy a career of around.

       Over a decade, their skills are maintained at a high level with yearly training refreshers.
