Canine Pneumonia in 2025: Vet-Backed Guide 🐶🩺

By Dr. Duncan Houston BVSc

📌 What Is Pneumonia?

Pneumonia is inflammation of the lungs, often with fluid or pus filling the air sacs, leading to coughing and breathing difficulties.

🧬 Types of Pneumonia

Infectious (viral/bacterial): Often from Bordetella, Streptococcus, or viruses like distemper, influenza—highly contagious.
Aspiration: Caused by inhaling food, vomit, or fluids—classic cause is regurgitation.
Fungal: From soil-borne spores like Blastomyces or Histoplasma—less contagious.
Irritant: Triggered by inhaling smoke, chemicals, or allergens, leading to inflammation.

👀 Signs & Symptoms

Persistent deep or moist cough
Labored or rapid breathing, wheezing
Fever, lethargy, loss of appetite, exercise intolerance
Nasal discharge and bluish gums in severe cases.

🔍 Diagnosis by Your Vet

History and physical exam, including auscultation for abnormal lung sounds.
Chest X-rays and sometimes an ultrasound to assess lung changes.
Tracheal wash or bronchoalveolar lavage for culture & sensitivity.
Blood tests to evaluate severity and guide treatment.

🛠️ Treatment & Hospital Care

Targeted antibiotics for bacteria, antifungals for fungal pneumonia.
Supportive care: NSAIDs, bronchodilators, expectorants.
IV fluids, oxygen therapy, and hospitalization in severe cases.
Nebulization and coupage to clear airways.

🏠 Home Care & Recovery

Warm, dry environment and low stress.
Humidified air or steam sessions to help loosen mucus.
Ensure hydration and offer easy-to-eat, palatable foods.
Rest and gradual reintroduction of exercise based on vet guidance.
Complete the antibiotic course and follow-up x-rays to confirm resolution.

🛡️ Preventive Tips

Vaccinate against Bordetella, influenza, parainfluenza, and adenovirus.
Minimize exposure to sick dogs and avoid high-risk environments.
Feed medications slowly and treat reflux to prevent aspiration.
Avoid smoke, chemicals, and pollutants.

📈 Prognosis

Many dogs recover fully with timely, appropriate care. Untreated or severe cases risking pneumonia complications like abscesses or chronic disease—early treatment is crucial.
