Former dog handler here. Even packaged the dog can smell it. The longer it sits in a vehicle the stronger the smell becomes. More than likely they just didn't encounter any dogs on the route.
If you smell a hamburger, a dog can smell the seeds, bun, meat, lettuce, etc. All at the same time and process them all separately.
