Why can't you add a dog's head to play inm terrier?

A magical rule invented by a group of inm people in order to find back their sense of superiority as elders in the field of short video.

At present, most cases of using a dog's head on the Internet are used to express "I'm a stalker, don't take it seriously", and some of them are making fun of other countries (it's nothing to laugh at other countries' artificial operation, but more to show their humor and speaking ability), and some of them are simply talking about shark arms with dignity.

In short, 90% of people who use dog heads are used to excuse themselves, let alone the silver dream circle. There are few people in foreign sub-cultural circles who look at your dog's head soybean.
