Six dogs from six different law enforcement agencies in southeast Michigan performed a training exercise and routine check at Trenton High School Wednesday.
Officers lead drug sniffing dogs around the parking lot to check for drugs and/or drug paraphernalia by sniffing the exterior of vehicles.
Superintendent Rod Wakeham said the district routinely requests training exercises be performed at the high school as a preventative measure.
"We do it once or twice a year to make sure our buildings are safe and secure, and it allows local law enforcement to put their dogs through different types of situations for training," Wakeham said.
Deputy Chief Steve Voss of the Trenton Police Department said the dogs sniff the outside of a vehicle to find out if there are drugs inside.
"If a dog gets a hit it gives them (police) enough probable cause to get a search warrant," Voss said.
Voss added officers had not reported any drugs found in the parking lot at about 1:30 p.m. Wednesday.
Officers and dogs also performed a demonstration for the emergency medical technician and criminal justices classes while at the high school.
