Why does Bomei bark whenever he sees any animal?

Dogs have their own personalities. Bomei is naturally active, curious and surly. This is the lovely place of Bomei. Hehe, how lovely. Bomei, who is raised by my aunt downstairs, is the dog king of our whole building. Every time a foreign dog passes through our building, that little Bomei will lead everyone to encircle the foreign dog and shout together. Even the golden retriever who doesn't like to scream will listen to his call. Join the choir.
