In ancient times, the image of a dog in people's minds was 'flattering, snobbish, shameless, and despicable'. Therefore, speakers are less likely to address others or themselves when using words that contain the word '狗'. It is also generally difficult for listeners to accept the use of the word '狗' when addressing themselves. However, with the change and rapid development of society, many new words containing the word '狗' appeared on the Internet to call others or call themselves. This paper analyzes the new meaning and image of new words containing '狗' from the perspective of semantics and image. Among them, there are three new meanings of the word '狗'. This paper mainly analyzes the new image of the word '狗', which consists of 5 categories: lonely image, miserable image, hard work image, negative image or others image. By contrasting the image color of neologisms with the inherent words, the traditional negative image color of dogs disappears slowly in neologisms, so neologisms containing '狗' are increasing more and more widely.
