It is a custom in some places to curse people with the word dog. People will think that using the word dog when swearing will be more insulting, but this behavior is wrong. Not only that, it is rude, impolite and insulting. The language is inappropriate.

Dogs are friends of mankind, and they should not be a tool for us to vent our emotions or express our dissatisfaction. Therefore, when we communicate with others, we must remain calm, respectful and polite, and avoid using offensive or insulting words to hurt other people's feelings.
