3 Bomb-Sniffing Dogs at Philadelphia Airport Fail Test

Three bomb-sniffing dogs assigned by the federal Transportation Security Administration to inspect cargo at Philadelphia International Airport failed recent recertification tests, according to a congressman who wants the dogs replaced.

U.S. Rep. Robert Brady, D-Pa., calls the situation "totally ridiculous."

TSA spokesman Greg Soule says the agency cannot confirm how many dogs are assigned to an airport or their status. But he says the rigorous nature of the yearly cerification tests means that some teams may need to go through remedial programs. He says in the meantime other security measures are used to keep passengers safe.

Brady says the agency should immediately send new dogs while the others are being recertified.

The TSA says 700 canine teams are in air, marine and mass transportation systems across the nation.
