Dogs barking every night may be due to missing their owners, boredom, wanting to go out, noises in the corridor, etc. Especially when dogs first arrive at a new home, they are not used to it and lack a sense of security, so they will be more vigilant. If the owner does not want the dog to bark, it is best for the owner to let the dog sleep next to him, pet the dog, talk to the dog more, or play with the dog for a while, which can make the dog feel more secure and relaxed.
