How to comment on looking like a person and acting like a dog?

Dragon humans are human beings and behave like dogs, so comment. People put on airs in front of people, and people put on airs behind people, which means that people are born to look and act like dogs and are often used to tease. People are people: born like people, people like dogs: people, but behave like dogs. This kind of person's own quality is not high, lack of education, lack of self-cultivation, and often lack of self-knowledge.
