There are many reasons why dogs bark at night, such as:

1. Dogs who have just arrived at their new home are not adapted to the environment and will feel lonely and fearful. Barking all the time can provide them with a sense of security. . If you want the dog to stop barking, the owner can put the dog in a cage before going to bed at night, and prepare some small toys in the cage.

2. The dog will be very anxious during the estrus period, because the mental excitement cannot be satisfied, so it will bark in the middle of the night. This is also a way of its courtship. In this case, the owner can take the dog for breeding or sterilization.

3. The dog barks very loudly If you hurriedly and kept scratching the door trying to wake the owner, it is likely that the dog found something dangerous. At this time, the owner must get up to check the situation and pay attention to safety. If it is all right, comfort the dog and let it sleep peacefully.
