Five prerequisites for training a puppy well:

1. Gain enough trust with the dog, so that subsequent training can proceed smoothly.

2. Then the temptation of food is the most important. Food can help complete many instructions during dog training.

3. Rewards and punishments must be timely. Dogs must be rewarded with food or snacks if they have completed good training, and they must be punished if they make mistakes.

4. The instructions and passwords for the dog should be fixed, so as to help the dog complete the training in a funny way.

5. The trained dog should wear a collar, so that the dog can understand the key points faster.
