Why Do Dogs Get Pneumonia?

1 Dog Pneumonia: Symptoms and Causes

I. About Dog Pneumonia

A healthy dog’s lungs are not full of fluid or pus. With pneumonia, alveolar inflammation makes the lungs swell and collect pus and fluid, causing breathing trouble because the chest loses room for air. Signs: constant cough, shallow breath, fever, hard breathing, coughing up blue/gray matter, lost appetite, drowsiness, easy fatigue.

Dog pneumonia signs are much like human pneumonia—breathing gets hard. Its hallmark: shallow breathing and coughing up green, yellow, even blood-tinged mucus, with a continuous high fever.

When lungs inflame, they can’t work normally, so the dog struggles for oxygen; in poor airflow it also gets drowsy and tired. Pneumonia also dulls the smell of food, lowering appetite.

II. Causes of Dog Pneumonia

Pneumonia ties to lung irritation, injury, and common infection. Causes include:

1. Inhaled irritants—smoke from owners smoking nearby, air pollution, or other sharp odors can inflame the lungs. Homes with regular smokers raise a dog’s pneumonia risk.

2. Aspiration of foreign matter—food or small objects accidentally drawn into the lungs.

3. Secondary disease—many illnesses hurt the immune system and damage airways; cancer or laryngeal paralysis make bacterial lung infection more likely.

4. Viral invasion—parainfluenza and canine flu can cause pneumonia and spread among dogs.

5. Bacterial infection—E. coli, Pseudomonas aeruginosa, Streptococcus, and Pasteurella are common causes; infection spreads between dogs.

6. Trauma—a hard blow to the chest (car hit, fall) can inflame the lungs.

The above are the signs and causes of dog pneumonia. Here is a reminder to dog owners who smoke: for your family’s health, please smoke less!
