WBRZ - Baton Rouge

UPDATE: Area crime-fighting organizations are testing their police dogs and handlers this week at Zachary High School.

David Williams has worked with police dogs for nearly 20 years. He says these yearly tests, "show you have discipline with your dog. That you can, if happen to have a call out and have to apprehend someone in a building, you have control over your dog."

Testing continues on Tuesday, when the test topic will be outdoor narcotics.

The public is invited to watch.
