Where did the expression pack "Dog Head" come from?

Among many expression packs, one expression pack has a very high appearance rate, and that is "dog head".

0 1. The source of the dog's head

This emoticon pack originated in Weibo, and is designed according to the very popular emoticon pack "God's Annoying Dog".

When people comment, in order to prevent accidental injury, they often add "dog head" to prove that they are friendly, and the content of the comment is ironic.

Later, on some platforms without dog-head emoticons, people often use words (manual dog-head) to express their irony.

Later, major platforms began to design their own face characters, and now the dog head has derived various versions and become an expression pack that can be seen everywhere.

Dudu's figure was also designed after seeing the expression of Shiba Inu's head, revealing a hint of banter in seriousness.
