As part of the Patrol Unit, our K-9 team consists of Officer Schack and his four-legged partner, Zeus. Zeus, a German Shepherd originally from the Czech Republic, joined the force in 2018 and is certified by the Law Enforcement Training and Standards Board of Illinois in patrol and narcotics detection specialties. Zeus is the third K-9 purchased by the Crystal Lake Police Department; the previous two dogs, Ike and Ace, retired after successful careers with the department.


In addition to Zeus’s initial eight weeks of training, Officer Schack and Zeus continue to train at least eight hours per week to further develop Zeus’s detection and tracking skills. The weekly training maintains their state certification and strengthens the bond between handler and canine.

Benefits of a K-9

Officer Schack utilizes Zeus for many situations including narcotics detection, article searches for discarded evidence or lost items, building searches, missing person or criminal suspect tracking, and crowd control. In addition to serving Crystal Lake, Officer Schack and Zeus assist other local police agencies and communities on calls for service that require the assistance of a K-9’s detection and/or tracking abilities. 

Community Outreach

Crystal Lake’s K-9 team make public appearances with community groups and conduct skill demonstrations for school children and civic groups. Want to meet Zeus for a community event? Contact Sergeant Behning
