What should I do if my dog ​​keeps barking at night?

The reason why dogs keep barking at night is because dogs will attract attention and keep barking at night because of a little noise outside the door. This is the original nature of dogs. If the owner doesn't want the dog to bark all the time, when the dog barks at night, he can raise his hand in front of the dog to cover its mouth, shake his head and say not to bark. Repeat this several times, and the dog will gradually understand the owner. It means it, but you can’t use a soothing attitude. The dog will think that it thinks it is doing the right thing, creating the illusion that it is being encouraged, and it will still keep barking in the future.
