What do you mean by throwing a dog? What joke?

If it is a cross talk joke, Mr. Ma Zhiming has a cross talk joke. If someone throws the dog out several times, the dog will find its way home. Finally, the owner went too far and couldn't come back, so he had to follow the dog to find a home (well, it's all planned, hi! )

If you are talking about online jokes, "throwing a dog if you don't agree with a word" is the game stalk and the battle line of the popular game undertale. Now that there is a Chinese version, there are two modes in the game: fighting and reconciliation. If you choose reconciliation, there may be lines such as "the other party doesn't want to talk to you" or "the other party ignores you and throws XXX to you". One of them throws a dog, and now it is made into a "throwing dog" expression.
