Why do you always use the word "dog" when swearing? Not a "cat"

Answer the question: Although the dog is a good companion of human beings, this animal used to eat shit, and in the eyes of the swearing person, it is the embodiment of the person he hates. In other words, he thinks that people don't eat shit, and people who are scolded are considered inferior, and they can't even treat him as a human being, so "eating shit" is a good way to belittle people.

And those who realize that this is just a habit of animals and don't treat it as a joke or metaphor are also educated and won't use "dogs" to call names.

Cats have never had more contact with people than dogs, so even cats have a lot of habits that make those people dislike and joke, but after all, there are few jokes and curses about them, maybe they have not been handed down, maybe we have never heard of them, which may lead you to think that "cats" are not used to curse people.

Animals used to curse people are different in every region of China. For example, Sichuan seems to curse people with turtles.
