SAN FRANCISCO—The San Francisco Police Department Tactical Canine Unit is mourning the loss of “Cavik” on Thursday, January 4 after being ill.

Cavik was a Belgian Malinois Shepherd, trained in patrol and explosive detection. He was born on April 29, 2009 in the Netherlands and traveled to the United States where he joined the San Francisco Police Department in 2011. K9 Cavik and his handler Officer Matt Maciel patrolled the streets of San Francisco assisting with suspect searches, conducting explosive sweeps for dignitary visits and large venues, assisting in S.W.A.T. operations, and performing canine demonstrations.

During his 7 years on patrol, Cavik and Officer Maciel made numerous arrests and assisted with security at countless special events and VIP visits; notably the 2012 and 2014 World Series, Super Bowl 50, and the 2012 U.S. Open.

“Cavik was always eager to go to work but also enjoyed time at home with Officer Maciel and his family. He will be sorely missed by both the Maciel family and SFPD family,” said the SFPD in a press release.
