Urgent! The poodle seems to be possessed! What's going on here?

Sometimes dogs play by themselves, and my family likes to run wildly after eating for a while, then climb on the carpet to threaten shoes, and sometimes pretend to be defeated by shoes. How big is your home? Too much space is terrible for a puppy. There is more than 100 on the first floor of my house, so I always follow my feet. Especially yours is too small to sell without learning anything from the dog mother. Suggestions for improvement are: first, play with him more and divert his attention; Second, buy a fence, not too big. Now let him stay mainly in the fence. For the puppy, he will feel more secure, and let him play more when he is older.
