This last video contains footage from the Chicago Police and Security Expo from 2008. You will see Darrel Hager from our Chicago location, and Fred Hassen the Sit Means Sit Founder and CEO, demonstrating how the Sit Means Sit system applies to all aspect of dog training including Police K9 Training. A Police K9 Handler, as much as anyone, needs to have control over their dog, especially in public situations. You can see Darrel’s pitbull exercise control and understanding as she goes directly from a full mouth attack to softly holding an unprotected hand in her mouth.  (312) 618-9663
