GRAYSON COUNTY, TX -- Campers at Grayson College got to meet a four-legged officer Tuesday.
Ivar, Denison's Police dog, demonstrated his skills sniffing out drugs and helping apprehend a mock suspect.
The class watched video of how police dogs are trained and how they work.
Despite the K-9's tough job, his handler says he's good-natured dog.
Denison police say Ivar's visit builds trust between the police department and the community.
The campers, who are spending the week learning about the police department, also get to hear about fingerprinting and patrolling.
