Well it looks like the body scanning company will have to find some new orders while Pedigree pet food may be looking to add more orders to the London Underground's account. Sniffer dogs will be used "indefinitely" across the Tube's network to seek out explosives.
According to the BBC: "The sniffer dogs being used, which tend to be labradors and spaniels, undergo an intensive eight weeks of training with their dog handler.
The spokesman added: "They operate just like dogs who search for drugs except they have been trained to sniff out explosives.
"They [the dogs] are far more effective than any machine."
Bloomberg's site continued: "The dogs, mostly spaniels, are being positioned at ticket barriers, sometimes three or four at a time, to check the smell of passengers' luggage, police spokesman Donal O'Reilly said in a telephone interview. On trains they are being used to search carriages for suspicious packages. As many as 30 dogs are being used in the operation.
I'd not seen many sniffer dogs on the Tube - apart from the one above which I saw in action at Piccadilly Circus last January. He/she was bloody lively and got into action pretty quickly, and with a dog barking and crawling all over someone or their bag it probably would be more effective (and scary) than a bleep of a scanner.
