At the foundation of new China, the public security organs in Shanghai, Nanjing, Tsingtao, Harbin, Xi'an, Nanchang etc. took the lead to set up police dog divisions, on the basis of taking over the police dogs of the police organizations of Japanese Puppet Regime and of the Kumintang Administrations. These divisions did a good job in solving criminal cases and searching narcotics, and thus made contributions to the consolidation of the new born people's regime.

     In 1957, the Ministry of Public Security built up two teaching & training teams of police dogs, and introduced some excellent breeding dogs from the former Soviet Union, Democratic Germany, and North Korea.

     On September of 1961, the Ministry of Public Security dispatched A Circular on Using Police Dogs, affirming the contributions made by the dogs to solving criminal cases, pursuing escapists, and guarding the frontiers and coastal borders, etc. and stipulating definitely the scope, principle and sanction of police dog uses.

     On November of 1962, the Ministry of Public Security sent out A Circular on Reinforcing Police Dog Works, which required that there should be more provision of police dogs, better equipments and treatment to handlers.

     On September of 1963, the Ministry of Public Security placed police dog work into Rules of the Work of Criminal Applied Science (Draft). Since then, this special technique has gained general recognition and sound development in public security organizations.

     By the end of 1965, the two training teams had run training classes for professional police dog officers for totally 20 times, training more than 1 000 handlers. And there were about 1 500 police dogs all over the country and more than 500 grass-roots units were equiped with police dogs.

     According to the statistics by the Department of Public Security of Shandong Province alone, from 1961 to February of 1962, police dogs went to the scenes for 2 560 times, did identifications for 768 times, and assisted solving criminal cases for 1 105 times. During this period, China started providing foreign aids of police dog.

     During the Cultural Revolution, police dog technical work suffered reproach and was finally stopped in 1968. In 1972, the Ministry of Public Security proposed in A Circular on Several Problems of Criminal Investigations that "Police dogs can be used when needed in frontier, coastal and remote areas". This made a step toward resuming police dog work, however, the special technique of police dogs couldn't be fully resumed due to the special historical background.

     Since 1979, after the Third Plenary Session of the Eleventh Central Committee of the Chinese Communist Party, two police dog bases in Shenyan and Nanjing were restored successively, and two new bases were set up in Nanchang and Kunming. Nanjing base was later transformed into Nanjing Police Dog Research Institute.

     On November of 1984, the first National Conference on Police Dog Work was held, issuing Provisional Regulations of Police Dog Work and A Six-year Plan for National Police Dog Work, which symbolized the development of police dog special technique. After that, the Ministry of Public Security established Shenyang Police Dog Technical School, and entrusted Nanjing Police Dog Research Institute with the task of starting publication of Police Dog, a bimonthly magazine.

     On May of 1988, a national conference was held to exchange experiences on police dog work. On the conference, it was proposed that police dog work be developed as an important part of criminal investigations.

     According to the statistics by police organizations of the whole country , each dog solved on average 4.3 criminal cases in 1989, and 5 cases in 1990. A 4-level network of police dog work was formed from the Ministry of Public Security down to provinces, prefectures and counties. Police dog bases were set up in most provinces, municipalities and autonomous regions. In this period, many national conferences on police dog work and of academic exchanges were held, 5 volumes of academic papers were published, 7 special textbooks were compiled, many research projects were awarded the Prize of Scientific and Technological Progress at national or provincial level.

     In 1996, Committee of Police Dog Division of China Criminal Scientific and Technological Association was set up. At the same time, there was also a faster development of police dog work in the Chinese People's Liberation Army, Armed Police Forces, customs, railways and forestry.

     From 1992 to 1998, the unfavourable system and the improper macro-management led to a sluggish or even lagging development of police dog technical work, and to a decline in some areas.

     On December 28th, 1998, the Ministry of Public Security decided to adjust management system of police dog work, which represents a new opportunity for the development of China police dog cause.

     On February 12th, 1999, the Ministry of Public Security held a meeting on the adjustment of management system of police dog work in Beijing. It was pointed out at the meeting that police dog work is an important component of criminal technical work, has a role that cannot be replaced by other technical means and therefore must be greatly strengthened. It was also pointed out that ministry-affiliated police dog bases, research institutes and police dog technical schools should shoulder the responsibility of promoting the development of China police dog work, brace up to make good use of the opportunity, work hard and train special personnel, turn out more achievements in scientific research in order to provide better conditions for investigating and solving criminal cases, and strive to open up a new prospect for police dog work. In addition, the meeting made a division of jurisdiction and responsibility of those ministry-affiliated police dog bases, research institutes and police dog technical schools, and decided focal points of their works.

     Criminal Investigation Bureau of the Ministry of Public Security set up a police dog technical work office on May 16th, 1999, and held regional meetings of police dog work successively in Nanchang, Shenyang, Nanjing and Kunming from April to June of the same year to act in the spirit of the administrative meeting of ministers, resuming and/or developing regional police dog technical work.

     Since the adjustment of management system of police dog work, the leadership of the Ministry of Public Security paid much attention to resuming and developing police dog work. The problems concerning police dog technical work were studied for three times at the administrative meetings of ministers, and three summaries of the meetings were issued, setting specific tasks and requirements on police dog technical work of the whole country.

     Party committees of the Criminal Investigation Bureau implemented the instructions of the leadership and party committee of the Ministry of Public Security. They decided that efforts should be concentrated on ministry-affiliated police dog bases, research institutes and police dog technical schools so as to promote the development of police dog work in each province. Thus, they took a series of measures to have an overall evaluation on and make some adjustments in the leading groups of ministry-affiliated police dog bases, research institutes and police dog technical schools. They practiced the personnel system and organization reform, unified the names and functions of internal offices, employed middle-level cadres through competitions, standardized the teaching system, perfected management rules and regulations on police dogs, and therefore started and/or resumed police dog technical work.

     From 2000 to 2001, the Ministry of Public Security successively held a symposium on teaching police dog techniques, a national conference on publicizing and reporting police dog work, a national conference on police dog breeding, a national conference on file management of police dog work, and a national symposium on training and using police dog techniques.

     As a result, some professional rules and regulations were worked out, such as Rules of Police Dog Breeding, Operating Rules of Police Dog Breeding Management, Rules of Police Dog Selection, Rules of File Management of Police Dog Work (Trial), Stipulations of Propagating Introduced and Original Domestic Breeding Dogs, Methods of Police Dog Earmark Management, Methods of Grading B-level Units of Police Dog Breeding, Rules of Training Police Dogs, Rules of Using Police Dogs, Criterion of Assessing the Training of Breeding Dogs, and Criterion of Assessing the Training of Young Dogs.

     In addition, A Development Plan for National Police Dog Technical Work from 2000 to 2001 was worked out. All these led to increased scientization, standardization and institutionalization of police dog technical work in our country.

     To promote the development of national police dog work, the Ministry of Public Security established Police Dog Breeding Management Committee of the Ministry of Public Security in Nanchang Police Dog Base, and Information Centre of Police Dog Techniques of the Ministry of Public Security in Nanjing Police Dog Research Institute, meanwhile it further defined the functions of the ministry-affiliated police dog bases, research institutes and police dog technical schools.

     In general, the ministry-affiliated police dog bases, research institutes and police dog technical schools take responsibility of directing their corresponding regions in police dog technical work.

     Specifically, Nanchang Police Dog Base focuses on police dog breeding and preservation of breeding dogs; Kunming Police Dog Base focuses on such research works as extension and use of Kunming dogs, training of police dogs and use of them on the sciences; Nanjing Police Dog Research Institute focuses on scientific research on police dog techniques and exchange of related information; Shenyang Police Dog Technical School focuses on training of police dog technical personnel.

     There have been 253 breeding dogs of 6 breeds introduced from Germany, France and Britain for police use, such as German Shepherd, Labrador Retriever, Rottweiler, Belgian Malinois, Doberman Pinscher, English Springer Spaniel, which have been distributed to the 4 above-mentioned ministry-affiliated units.

     There have been up to 7 breeds of police dogs used in our country, which have definitely improved the structure of our police dog breeds.

     During this time, the leadership of the Ministry of Public Security for many times heard reports on police dog technical work; Criminal Investigation Bureau convened a telephone conference on national police dog technical work, and held the first nationwide police dog technical competition in Nanjing on October 22nd, 2000. These have greatly facilitated police dog work in the whole country.
