First, read the English article below.

Perhaps there are other issues causing a bit of unrest in your dog. Are you packing for a trip or moving? Are there guests in the house? A new neighbor? Loud noises? Just remember, dogs appreciate a routine.  A small change to you (like moving your bedroom furniture) may seem like a big deal to the dog. Some dogs are more anxious than others, so be patient and think about things from your dog's perspective. Then, you can make changes accordingly. If this is an older dog that has been quiet and content before, try to determine if there is a medical problem. Talk to your veterinarian about any unexplained changes in your dog's behavior, including appetite, energy level and ability to move comfortably. Pain or needing to go outside to eliminate in the middle of the night can cause a pet to whine and be restless during the night. It may take a few days (and nights) to adjust to the new household and routine. Establish ground rules at the beginning to create a good routine. This will help your puppy understand the end of day rituals that lead to getting to sleep in the new household. Feed your puppy at the same time in the evening, followed by a trip outside 15-20 minutes later to eliminate. Place the pup in his crate, which should be in your bedroom so that the puppy is close by. This way, he can communicate when he needs to go outside to eliminate during the night.
