Four Connecticut State Police drug-sniffing dogs are being credited with helping troopers collar two men on drug-trafficking charges.

“Troopers from Troop G stopped a truck on I-95 in Darien,” state police said of Friday's bust. “When something didn’t smell right, the big dogs were called in.”

Those big dogs, police said, “alerted” on the truck, a U-Haul rental, and a search turned up 420 pounds of marijuana.

They were each being held on $100,000 bonds pending court appearances, the station reported.

Their truck was stopped on the busy interstate in Darien, heading in the direction of New York City, police said.
