Mike D'Abruzzo, who trains guard dogs, showed IE how household pets react when burglars break in.
"Most people really do not know what their dogs would do," he said.

The homeowners told IE: “I’m kinda surprised. I’m surprised he didn’t lunge at him.”
At another house, two big dogs named Sam and Mojo barked at the “burglar,” but they seemed intimidated and eventually backed off.
