Dogs can help track down DVD pirates - but don't expect them to be able to distinguish between copyright and pirated works. Leave that to the lawyers. Two black Labradors, Lucky and Flo, displayed their talents at the Customs and Excise Department's training school yesterday. The two-year-old dogs successfully and quickly found the luggage containing optical discs among packages and containers. Lucky and Flo, who are on a world tour, are the first two dogs trained to find optical discs in packages piracy syndicates use for smuggling stolen movies, music and software. The dogs search for the unique scent of polycarbonate and other chemicals on the optical discs. The training programme was initiated by the Motion Picture Association of America in 2004. The dogs were trained in Northern Ireland for about eight months. Veteran dog trainer Neil Powell said there was basically no difference between training sniffer dogs for optical discs and drugs. Customs said it had no plans to buy the dogs or train its own.
