Police dogs on patrol at McCormick Place

Bomb-sniffing dogs are on patrol around McCormick Place as more visible security measures fall into place before the NATO summit.

One of the dogs is Deja, a 4-year-old Labrador retriever that is certified at detecting explosives and firearms. The dog completed 16 weeks of training and will be working during the conference.

"It's rigorous training. It's every single day. They're a food reward dog. They only eat when they find explosives," Mitchell Wido said.

The dogs are part of the security plan to serve the NATO mission -- although handlers will not reveal any more information.

When the dogs do find something, they are trained to simply sit down.
