Why is my dog barking non-stop?

Non-stop barking in dogs may be caused by stress response, heat, unmet physiological needs, diseases, and other reasons.

1. Stress response: When dogs are scared or in a new environment, they may experience a stress response, which can lead to constant barking. In this case, it is recommended that the owner transfer the dog to a quiet environment, stroke its head to comfort it, or let it stay in a corner alone. It is also advised to minimize changing the dog's environment as much as possible, especially before the vaccine is fully administered, to avoid a decline in resistance due to stress and infection.

2. Heat: During their heat cycle, dogs may exhibit constant barking and irritable behavior. Male dogs may urinate randomly, and female dogs will have bloody vaginal discharge. If the owner does not want to breed the dog, they should avoid exposing the dog to the opposite sex during this time and consider spaying or neutering the dog after the heat is over.

3. Unmet physiological needs: Dogs may constantly bark when they are hungry, thirsty, cold, or want to go outside. In this case, the owner should promptly satisfy their needs by providing enough food and water, ensuring warmth, and spending more time playing with the dog. Once the dog's needs are met, the barking will stop.

4. Diseases: When dogs suffer from conditions such as gastroenteritis, respiratory inflammation, trauma, or pancreatitis, they may experience discomfort and pain, which prompts them to bark constantly to inform their owner. The barking is usually accompanied by symptoms such as loss of appetite, decreased mental state, vomiting, diarrhea, runny nose, cough, and fever. If these abnormal symptoms are noticed, the dog should be taken to a veterinary hospital immediately for inspection and treatment.
