The Transportation Security Administration has shown off dogs that are being used to detect explosives and explosive components at Detroit Metropolitan Airport.

The TSA uses passenger-screening canines to identify and locate potential explosive threats at security checkpoints. Authorities recently received four specially trained dogs. The TSA held a demonstration for media Thursday.

Officials say the dogs are different from other explosive-sniffing dogs that have been used at the airport and elsewhere in the past.
