The systematic breeding of police dogs begins with breeding. Like Shenyang, the base has its own feeding room, and puppies are assigned to cooperative units for puppy training after breeding. When puppies are about 6 months old, dogs that are screened back to the base after puppy training will be trained by police dog trainers. Training mainly includes:

① Obey the subjects (sitting, lying, standing, leaning, jumping, calling, accompanying, dragging and taking things).

② Users (drug search, explosion search, blood stains, physical evidence, biting, stalking). There is no elimination rate of obedience subjects, because these subjects can be trained as long as they are not congenitally deficient, but dogs with good excitability can learn all obedience subjects within half a month.

However, the elimination rate of users is very high, which really depends on the dog's own ability, and the role of people is auxiliary. However, they all tried to adopt the adjustment system. If dogs can't get blood and physical evidence, they will search for drugs and explosives. If they can't, they will take a bite and take turns to try, so that the elimination rate can be lower.

China has four police dog bases, which are located in Nanjing, Nanchang, Kunming and Shenyang. The main breeds of police dogs in China: German shepherd (black back), Belgian short-haired shepherd (Malinua), Labrador, springer, Dutch shepherd, Kunming, Rottweiler, etc.
