There are wild dogs in the community, how to solve them?

1 10 didn't catch it when it came ... It seems that this dog is the owner, which is much more useful than 1 10 ... Dogs usually bark in the building, and most of them find anything unusual. You can go to the corridor first. Second, make sure that this dog is really a wild dog without its owner. (Some people like to raise), the owner can contact the owner.
