First of all, Su Mu is very sociable and will not fight with Jingba, so you can rest assured. Secondly, when moulting, a large amount of hair will be shed, and the floor needs to be mopped every day. Su Mu has little body odor, is very smart, understands human nature, and knows what you want to do. If he is a male, he will be very beautiful when he grows up. When I was young, I had to buy teething sticks or the like, otherwise the furniture would be chewed up. If there are no problems with the above, then the rest is to walk the dog every day. It doesn't matter on the sixth floor. She will happily follow you down, but you have to hold her back to avoid scaring others if she rushes down before you.
