Since 2023, the K-9 team has participated in the investigation of 51 major criminal cases and completed 15 major national security tasks assigned by the Ministry of Public Security, ranking first in several national combat competitions.

The Shanghai police will continue to strengthen the professional training of police dogs and promote the standardization and application of police dog technologies, contributing to social security stability, according to the bureau.

As information technologies are increasingly applied in public security, police dog technology is also advancing into a digital era. Chen Jiajun and his K-9 "comrade" Tank are testing new equipment.

Jointly developed with Shanghai K9 Intelligent Technology Co, the equipment enables handlers to command the police dog remotely during dangerous crimes or rescue scenes where the handler and police dog cannot go together.

Apart from crime investigations, police dogs are also making eye-catching contributions to raising public awareness of public security.

"Most people have a special affinity with animals and are curious about how police dog work. So, with the police dogs, we are participating in many activities to raise public security knowledge and promote the mutual trust between the police and the public," says Chen.
