Seek a novel about whether people become dogs or dogs become people.

Hello, it suddenly occurred to me that this book was searched and searched on the Internet, and only your question was similar.

Does it mean that dogs live in sewers and then hit walls or something and become people? The police took him away and went to school to take the entrance exam. Just touch the earthworm scar on his forehead and the whole meeting will be over. Later, it was found that the PE teacher seemed to be his relative at school. When he became a man, he would accelerate his aging. It seemed that his father's hair was later found in the market.

Excuse me, is this the book you read? I am looking for this book, too. If you know the name and author, can you tell me? Thank you.
