Dog meat can't be served on the table, which means that dog meat can't be served at the banquet. The reason for this is the following：

1. In ancient times, eating dog meat meant breaking up and leaving, so dog meat naturally could not appear at banquets.

2. Dogs are faithful friends of human beings. Many people think that eating dog meat is immoral, so dog meat can't be served.

3. Dog meat has derogatory connotations in China culture, such as "being friends with friends" and "being heartless". These words have bad meanings, which also affects the image of dog meat on the table. In modern society, with the improvement of people's living standards and the opening of their minds, many people no longer stick to traditional concepts, but choose food according to their own preferences and tastes.
