Although dogs like to bark very much, as long as their owners educate them properly, they will generally not bark. So why do dogs bark at 2 or 3 o'clock in the middle of the night? What should you do if you encounter a dog barking at 2 or 3 o'clock in the middle of the night? In fact, the dog owner should first analyze several situations that the dog may encounter, and then think of countermeasures. Let’s take a look at the reasons why the dog barks at 2 or 3 o’clock in the middle of the night.

1. Hungry

If the dog has not eaten for a long time or is not full, it will keep barking when it feels hungry in the middle of the night, trying to get the owner to provide food. Therefore, it is recommended that owners feed their dogs regularly and rationed food every day to prevent their dogs from barking due to hunger. They can also prepare some water and dog food in the areas where their dogs move, so that their dogs will eat by themselves when they are hungry.

2. Feeling threatened

Dogs have very sensitive senses of hearing and smell. When they feel that there is a threat around them, they will bark to intimidate the other party, and at the same time attract the owner's attention and seek help from the owner. At this time, the owner needs to check the surroundings to ensure that the environment is safe, and just pet and comfort the dog.

3. Estrus

During the period of estrus, dogs will also have symptoms such as barking in the middle of the night, being irritable and restless, in order to attract the attention of dogs of the opposite sex. This is a normal phenomenon. At the same time, male dogs will urinate everywhere, and female dogs will have bloody secretions from their vaginas. In addition, during the period when the dog is in estrus, the owner needs to pay special attention to the hygiene of the external reproductive organs and clean the dog regularly, especially the female dog. If the owner has no need for the dog to breed offspring, the dog should not be exposed to the opposite sex during this period, and can go to a pet hospital for sterilization after the estrus is over.

4. High energy

Some dogs will bark non-stop at night because they are energetic and spend a lot of time resting during the day. In this regard, the owner can prepare more toys for the dog so that the dog can consume excess energy through more activities during the day. If you have time, you can also take the dog out for more walks, so that it will feel tired at night and will not have the energy to bark.
