Freckle has skills that are not to be sniffed at.
The 10-year-old has helped out at hundreds of blaze investigations as the county's fire investigation dog.
As he gets older he will be helping handler Dave Coss pass on his abilities to his successor Dexter.
Dave is the regional fire investigation dog handler and with Freckle works for fire services in Leicestershire, Nottinghamshire, Derbyshire and Lincolnshire.
Freckle uses his talent to sniff out any trace of accelerants, such as petrol diesel, turps and meths, at the scenes of fires.
He was called on during the investigation into the fire at Wood Hill, Spinney Hills, Leicester, where a family of four lost their lives last September.
Shehnila Taufiq, 47, her daughter, Zainab, 19, and sons Bilal, 17, and Jamil, 15, were asleep when petrol was poured through the letter box of their home and set alight in the early hours.
Two men were convicted of murder and six other young men were found guilty of manslaughter at a trial.
Dave said: "We were called in during the early house and Freckle sniffed out the petrol on the floor at the front door.
"Once he identifies the presence of an accelerant the investigators take samples and it just helps speed their job up."
Dave said he thought said Freckle has got about another year of the job left in him.
"We were looking for a dog to take over the mantle and the South Yorkshire police dog handlers recommended Dexter as having potential.
"So I have taken Dexter in and he is busy getting to know Freckle."
Dave, who lives in Mansfield and has his office in Chesterfield, now has both dogs living with him at home.
He said: "I can't believe how well they get on with each other.
"They have got separate beds but they sleep together in one bed at night. It is lovely to see."
Freckle is a Sprocker - a cross between a Cocker Spaniel and a Springer Spaniel.
Dexter is a five-month-old pedigree Cocker Spaniel.
He said the way they train the dogs to sniff out accelerants is to put one of the liquids on a tennis ball and encourage the dog to fetch it.
This process continues until the accelerants are put on the ground and on other surfaces and if the dog sniffs it and responds it gets the tennis ball as the reward.
Dave said: "It does not happen overnight and does taken weeks of training. Dexter is too young at the moment to start training but we can start the process next year.
"Freckle has proved he has real talent and we hope he helps pass that onto Dexter."
