There are many training subjects for police dogs, hunting dogs or play dogs. Must correctly grasp the training essentials, so that the dog can quickly develop a good and stable conditioned reflex. (一)诱导     诱导就是在训练中利用食物、物品、自身行为以及其他因素，诱导犬做出某些动作，借以建立A means of conditioning. This method is guiding and can arouse the appetite of the dog, especially the food that the dog loves to eat. Because this kind of stimulation is active, the actions made by the dog are naturally lively and willing to perform, especially the training effect of the subjects is better. However, its disadvantage is that it cannot be guaranteed that the dog can make movements smoothly and accurately as required under any circumstances, especially when the method is used improperly, such as excessive reward and food. Therefore, when using this training method, you should pay attention to the following 3 points:     First, the use of induction should be grasped at the right time, and it should be combined with a certain intensity of coercion, so as to ensure the smooth progress of the training , and can maintain the excitability of the dog. Prevent the practice of inducing substitutions for passwords and gestures.     Second, it is necessary to prevent bad contact caused by induction. For example, if the dog is moving but not holding the object, it is caused by inattentiveness in training.     Thirdly, it should be used appropriately according to the nerve type and characteristics of the dog. It can be used more for calm, quiet and less excited dogs, while it should be used less for excited and flexible dogs. (二)强迫     强迫是使用机械刺激和威胁音调的口令，迫使犬准确地做出动作。 The method of forcing is mainly used in the initial stage of each training subject, that is, in order to strengthen the formation of conditioned reflex, it is used in the initial stage, or under the influence of external incentives, it is used when the predetermined subject cannot be carried out. But pay attention to the following two points:     First, when using compulsion, pay attention to timely, moderate, combination of password and mechanical stimulation of corresponding intensity, and combination with reward. Excessive compulsion can easily lead to inhibition of dogs and affect human attachment. When the dog makes the correct action, in order to ease the dog's nervous state and consolidate the conditioned reflex, it is necessary to give sufficient rewards (give food or petting, etc.), so that the dog knows what to do and what not to do.     Second, it should be different from dog to subject, and it should be used with caution to avoid adverse consequences. (三)禁止     这是为了制止犬的不良行为而采取的一种手段。 It is a NO password with a threatening tone, combined with a powerful mechanical stimuli. For example, when dogs chase livestock and poultry, pick up food anywhere or bite people, they should issue a non password, and use strong mechanical stimulation to stop them. When using the prohibition password, you should pay attention to the following two points:     First, when stopping the dog's bad behavior, the owner's attitude must be serious, and the prohibition must be timely. The most effective time is when the dog has bad behavior. Stop it now. Serious attitude is by no means synonymous with beating and scolding. Whenever the dog hears the order, it must be rewarded.     Second, the intensity of stimulation must be treated separately according to the characteristics of the dog, especially for puppies. When the non password has formed a conditioned reflex, that is, when the dog can hear the command, it should be combined with mechanical stimulation frequently to avoid the response to subside. (四)奖励     奖励是为了强化犬的正确动作，巩固已培养的能力，调整犬的神经状态而采取的一种手段. The methods of reward include feeding, touching, granting wandering and praise (sending a good password) and so on. Generally, in the early stage of subject training, in order to make the dog quickly form conditioned reflexes and consolidate the learned movements, feeding and stroking should be used, and rewards should be given in combination with praise. Pay attention to the following two points for rewards:     First, rewards must be timely, and different reward methods should be used according to different situations.     Second, when rewarding, the host's attitude must be amiable.
