With American airport security on the top of people's minds, TSA dogs that are trusted to sniff out bombs at Philadelphia International Airport failed federal testing.
This is a developing story that actually started when the dogs were tested late last year, reports Fox 29's Jeff Cole.
The Transportation Security Administration says its canine teams are an "invaluable asset" to defeat attempts to put explosives in the county's transportation system. But Fox 29 Investigates has learned that, at least for now, the TSA has lost that asset at Philly International.
