Sniff, sniff

Talking to one of my colleagues who wanders around with the "sniffer" dog today, I asked him, in the light of the latest wave of terrorist bombings, how do Muslims deal with a copper aiming a dog towards them?
Not that I particularly care about their sensibilities, I just thought it would make the officer more suspicious of the person.
"Un-bloody lucky" was the answer "the dog's got a job to do".
