Meet Alfie - one of Britain's most successful police dogs, who has sniffed out more than £11 million of drugs, cash and guns.
The hardworking springer spaniel joined Staffordshire Police in 2006 and his work with handler Julie Hargreaves has led to more than 400 arrests.
When the nine-year-old is not finding illegal substances or stolen money, he uses his spare time to educate schoolchildren about how to stay safe around animals.
Ms Hargreaves said: "He's the best dog I could ever have asked for - he constantly goes above and beyond expectations.
"It's difficult to keep count of the times that he has found things we had been desperately looking for with no luck and kept the community safe."
In his eight years in the force, Alfie has sniffed out £8 million in drugs alone.
During a raid on a car by the Central Motorways Police Group in August, Alfie came up trumps with one of the biggest single finds in history.
Police stopped a vehicle where intelligence suggested drugs may be concealed on board, but officers could not find anything in a search.
It was only when Alfie was left to sniff around the car that he unearthed a large quantity of class A drugs with an estimated street value of £4 million.
His ability to smell traces of ammunition and weapon components means he also helps to take guns off the streets with a total find value of £1 million.
After an armed robbery in Alsager, Cheshire, in 2011, Alfie searched the house where the perpetrators had hidden and managed to find the weapons used in the theft which could then be used in evidence.
And, thanks to extra training three years into the job, he is also able to detect the special ink used to print money and can sniff out all sterling and euro notes. He once found a haul of £10,000 in cash believed to be the profits of crime.
Alfie retired in October and is being supported by the Staffordshire Retired Police Dogs Scheme now he is no longer in active service.
Ms Hargreaves added: "Although I was very sad to see him retire, I know he'll enjoy his new home."
