Hero sniffer dog proves she's top dog at Heathrow airport

Jessie the springer spaniel, the youngest member of the UK Border force, has proven she has a keen nose for cash. The top dog sniffed out £1million cash smuggled through Heathrow in her first five months on the job. It goes to prove that while the airport has plenty of high-tech security, when it comes to tackling crime instinct is not to be sniffed at.
