The North East's only hydro-carbon detection dog has been put through his paces against the latest technology.

Scrappy has been helping gather evidence at suspicion fires for five months by sniffing out flammable liquids.

He wears a harness and special boots, donated by a North East company, to protect his paws.

Teesside University are comparing the cocker spaniel's skills to devices used by the fire service to detect hydro-carbons like petrol which may have been used to start fires.

So far, they have found that the machine can't trace chemicals after 8-10 days whereas Scrappy has no trouble at all finding the scent.
