The main reasons for puppies to stay up and whine in the middle of the night are as follows:

1. A sudden change in living environment, some fear of the new environment, and the puppy is not used to it. The owner can put it in the kennel Or put something with the owner's scent next to it, or put the dog closer to you to make the dog feel safe.

2. The dog may be sick and feel uncomfortable. If this happens, you should pay attention to the dog’s symptoms in time.

3. Dogs need to eat some food because they will whine because they are too hungry.

What to do if your dog doesn’t sleep in the middle of the night:

1. Let the dog consume its energy first, whether it is through playing or exercising.

2. When going to sleep, please start from the moment you turn off the lights and do not have any form of interaction with your dog, whether it is language or movement. Even if we scold it or hit it gently, it will think that we are playing with it, so we should not think about sleeping quietly. The dog's various movements and barks will continue to appear.
