3. The same sound and visual symbols must be used repeatedly to make the dog remember it thoroughly.

4. The sound and visual symbols should be clear and easy to remember.

5. Don’t teach multiple things at the same time, but make them understand one by one.

6. You must train with love and perseverance. During the training process, if the dog is happy to do it, or if it does it correctly, reward it immediately. Usually the trainer uses the left hand to comfort, encourage and gain trust; and uses the right hand to punish the dog. Of course, the most important thing is to let your dog understand your password and the meaning of your actions. If you disobey orders, you should seize the opportunity and act decisively to treat it indifferently. Remember, punishment after the fact is absolutely wrong and can cause misunderstandings in dogs. For example, if it associates your calls with beatings and scoldings, then your commands or actions will not receive appropriate responses. In particular, violence or whipping training has long been out of use by dog ​​trainers and has become outdated. After all, trust between the trainer and the dog is the main training element.
