The sudden abnormality of a dog not sleeping at night may be caused by hearing movement outside the door, hunger, fear, or feeling cold. It is best to prepare dog food and water for the dog before going to bed, and take the dog with you after dinner. When the dog goes out to defecate, if the weather is cold, you should pay attention to keep the dog warm to prevent the dog from catching a cold.

Tip:
If the dog does not want to sleep by itself because it is scared or lonely, you can let the dog sleep next to the owner and soothe the dog's mood.
