Can a commercial house keep a pet dog?

Yes, but pomeranians need careful care. If they accidentally get sick, they will spend hundreds of dollars in the pet hospital. The most important thing for you to live in a commercial house is to buy a dog toilet and put it on the balcony to teach him to pee in the dog toilet. The dog won't pull in its own place, so let it play indoors, sleep indoors and pull the dog toilet on the balcony. If you put it on the balcony to sleep and play at the end of the day, it will go into the house to pee. I suggest you get a Beijing Ba dog or something. It's easy to take care of, and it won't be too much.
