Several county agencies join forces today to train their drug dogs and their officers.

During routine traffic stops, or serving a search warrant, dogs and their partners must work as a team to get the job done.

Monongalia, Ohio, Taylor and Marshall County agencies set up scenarios.

If the cars had drugs in them the dogs would alert their owners.

In an instance today, a canine found bags of marijuana, but they're also taught to sniff out heroin, meth, and cocaine.
