1. Observation: I don't know if anyone has carefully observed the dog. The dog has rich expressions, and the expression of happiness, anger and sadness is perfect. Dogs will not hide their emotions. At that time, emotions will evolve into rich expressions and body language.
2. Contact: If you just contact a dog, it will wag its tail at you with the idea of making friends because of curiosity at the beginning, and at the same time, it is timid and not dare to approach, and it is ready to attack or run away at any time with a little hostility and fear. At this time, you can slowly wave to it (don't frighten it) and signal it to come, and it will come closer and closer until you touch its head and make it feel safe.
3. Communication: I don't know if anyone will say how to communicate with dogs. In fact, dogs are very smart. They often talk to them and communicate with each other. They can understand some simple signs, such as picking up things, shouting at them, and so on. (Be patient. Some things can be repeated several times, and they can remember)
