Why is my Japanese Chin coughing?

When Japanese Chin starts coughing, it is usually a symptom potentially affecting the respiratory system. However, cough can be caused by a variety of diseases, which can be divided into four categories: autoimmune and inflammatory diseases, sources of infection, senile and degenerative diseases, and congenital diseases.


Autoimmune and inflammatory causes of cough

Allergy and asthma are the two main causes of cough. Like humans, the Japanese Chins are allergic to a variety of irritants, including certain foods, vaccines, drugs, fleas, second-hand smoke, and other environmental allergens.
Asthma is usually more common in dogs of any breed during cold or hot weather, and its worst symptoms can be affected by their age. When the dog has asthma, she will show greater dyspnea, which tends to produce wheezing. A cough usually breaks out after an asthma attack.

Infectious causes of cough

Infection can be caused by four pathogens: viruses, bacteria, fungi and parasites. In many cases, canine cough is a sign of a more serious problem, such as canine distemper virus, heartfilariasis, pneumonia, Valley fever and other infectious diseases, and of course, canine cough.

Canine distemper virus

Canine distemper virus is a very dangerous disease, which can be proved to be fatal, because there is no cure at present. However, there is a vaccine that can help protect your pet from the infection. Symptoms of canine distemper include drowsiness, cough, fever, loss of appetite, tremor and seizures.
Cardiofilariasis is caused by an 8 to 10 inch worm that occupies the dog’s heart. It then produces tiny larvae that enter her dog’s blood. Common symptoms of the disease include persistent cough, weakness, dyspnea, loss of appetite and weight loss. Without treatment, heartworms can lead to heart failure and severe lung disease.



Pneumonia usually occurs in dogs after a long period of respiratory disease or immune system suppression. Symptoms usually include fever, runny nose, and persistent loss of appetite.


Cough is the most common or serious respiratory infectious disease in Japanese Chin The disease can lead to dry cough in dogs, often retching or vomiting after coughing. Other symptoms include a runny nose and eyes, as well as loss of appetite.

Senile and degenerative causes of cough

There are several age-related diseases that can cause cough attacks in dogs, including congestive heart failure, laryngeal paralysis, and some types of cancer. Congestive heart failure may affect dogs of any age, but it usually occurs in late middle age to old age. The most common condition is caused by a leaking heart valve. In some cases, the puppies may have valve leakage at birth, and when this happens, the puppies will show signs of congestive heart failure earlier. The most common symptoms of congestive heart failure are cough, dyspnea and exercise intolerance. When Japanese Chinese suffers from laryngeal paralysis, it is difficult for him to breathe comfortably because when he inhales, the curtain on the inside of his throat will not move. This situation is due to the deterioration of laryngeal nerve function, the laryngeal nerve basically paralyzed.
