Chronic Bronchitis

Chronic Bronchitis in Dogs is a long-term inflammatory condition that affects the bronchial tubes—the airways that carry air to and from the lungs. It is characterized by persistent coughing that lasts for at least two months or more without any other identifiable cause such as infection, heart disease, or parasites. The inflammation causes the airways to become irritated, swollen, and produce excess mucus, making it harder for the dog to breathe comfortably.

The condition is most common in middle-aged to older, small-breed dogs, such as Cocker Spaniels, Poodles, and Terriers, though it can affect any breed. Environmental factors such as exposure to cigarette smoke, air pollution, dust, or strong chemical fumes can contribute to or worsen the condition.

Symptoms of chronic bronchitis include a dry, hacking cough that may worsen with exercise, excitement, or cold air. Some dogs may experience wheezing, gagging, or retching after coughing, and in severe cases, difficulty breathing or reduced activity levels. Unlike infections, the condition does not usually cause fever or sudden illness but rather develops slowly over time.

Diagnosis is made by ruling out other causes of coughing. Veterinarians may use chest X-rays, blood tests, airway cytology, or bronchoscopy to evaluate the lungs and airways.

Treatment focuses on managing inflammation and reducing symptoms, as there is no permanent cure. Common treatments include corticosteroids to reduce airway inflammation, bronchodilators to help open the airways, and cough suppressants if needed. Managing body weight, avoiding irritants, and using a harness instead of a collar can also help reduce strain on the airways.

With proper management and regular veterinary monitoring, most dogs with chronic bronchitis can live comfortable and active lives, though they may require lifelong medication and care to control the condition.
