K-9 Ritter of the University of Wisconsin-Madison Police Department retired on June 4, 2026, after eight years of service [1].
The retirement of a specialized K-9 marks the end of a critical security partnership on a major university campus. Ritter served as a primary asset for explosives detection and human tracking, providing a layer of safety for students, faculty, and visitors.
Ritter worked as a team with Officer Justin Zurbuchen [1]. Together, the pair managed 327 deployments [1]. Their duties included securing countless special events and attending every Wisconsin football home game during Ritter's tenure [1].
To mark the occasion, the department held a traditional "10-42" sign-off ceremony [2]. This radio code is used to formally commend a veteran K-9 for loyal service as they exit active duty [2].
"Ritter and Officer Justin Zurbuchen have worked side by side as an explosives-detection and human-tracking team, helping keep our campus safe through 327 deployments, countless special events, and every single Wisconsin football home game," the University of Wisconsin-Madison Police Department said [1].
During the ceremony, a radio operator addressed the dog directly. "K9 Ritter, we thank you for your eight years of service," the operator said [2].
The transition from active duty to retirement follows a standard tenure for police dogs. Ritter's career spanned eight years [1], during which the dog acted as a veteran presence within the UW-Madison security infrastructure [2].
“K-9 Ritter retired on June 4, 2026, after eight years of service.”
The retirement of a highly deployed K-9 like Ritter highlights the operational reliance of campus police departments on animal partners for specialized security. With 327 deployments, Ritter's role was integral to the risk management of high-traffic collegiate events, meaning the department must now integrate a new certified team to maintain the same level of explosives and tracking capability.
