Deputy D. Perez & K-9 Brixx

K-9 Handler Deputy D. Perez joined the San Francisco Sheriff’s Office in April 2006 because he wanted to serve the city where he was born and raised. He started his SFSO career at County Jail #5, then moved to the Civil Unit, where he eventually ran the Eviction Assistance Unit, before joining the K-9 Unit. 

Deputy Perez is also a member of the Sheriff’s Office’s Emergency Services Unit, Crisis Negotiation Team, and the Honor Guard. He earned a Bachelor’s degree from San Francisco State University in Criminal Justice.

His K-9 partner, 7-year-old German Shepherd Deputy Brixx, is trained in explosives detection. Deputy Perez and Brixx patrol high-profile buildings and facilities, such as San Francisco City Hall and Levi’s Stadium, where the San Francisco 49ers play, making sure they are safe for everyone. In times of emergencies, Deputy Perez and Brixx also provide mutual aid from other agencies and counties. Deputy Perez also takes Brixx to schools, fundraisers and other events to showcase Brixx’s skills.
