Saying that others are dogs or dog people means that the person being scolded has a bad personality, which means that this person is not very good. Therefore, when describing the meaning of dogs and being stingy, some people say that they are dogs and dog people, and they know that they have done something wrong, but they still feel that what they have done is right. In this way, some people say that they are dogs and dogs, and even dogs are not as good as dogs. A kind of venting is also annoying when others are doing things.
