Canine Pneumonia: Warning Signs That Require Hospitalization
By Rexvet

1. Causes of Pneumonia: When Infection Reaches the Lungs
Pneumonia is not a simple upper respiratory infection. It occurs when pathogens or foreign material reach the alveoli, the deepest part of the lungs where oxygen exchange happens.
Common causes include:
Bacterial infections (primary or secondary)
Viral infections that weaken lung defenses
Fungal organisms in endemic regions
Aspiration pneumonia, caused by inhaling vomit, saliva, or liquids
Once the lungs fill with inflammatory fluid, oxygen transfer drops sharply. At this stage, home care is no longer sufficient.
This is a lower respiratory disease with systemic consequences.
2. Systemic Red Flags: Signs the Body Is Losing the Fight
Unlike mild respiratory infections, pneumonia triggers whole-body illness.
Critical warning signs include:
High fever above 39.5°C (103.1°F)
Complete loss of appetite
Profound lethargy
Extended neck posture, used to maximize airflow
Rapid or labored breathing even at rest
These symptoms indicate that the infection has moved beyond local irritation into systemic compromise.
If these signs are present, waiting is not a safe option.
3. The Cough: Why “Wet” and “Bubbly” Is a Medical Emergency
The cough associated with pneumonia is distinctly different.
Typical characteristics:
Moist, productive sound
Crackling or bubbling quality
Often accompanied by nasal discharge
Worsens when lying down
This sound reflects fluid and pus inside the airways, not irritation alone.
A wet cough means the lungs are involved.
4. Diagnosis: Why Pneumonia Cannot Be Confirmed at Home
Pneumonia cannot be reliably diagnosed by sound alone.
Veterinary confirmation requires:
Thoracic radiographs (chest X-rays) to identify lung consolidation
Auscultation revealing crackles or crepitant lung sounds
In some cases, bloodwork or airway sampling to identify the pathogen
Treating without imaging risks missing the severity—or the cause—of the disease.
Accurate diagnosis guides survival, not guesswork.
5. Intensive Treatment: Why Hospital Care Is Often Required
Moderate to severe pneumonia requires aggressive, monitored therapy.
Standard treatment protocols include:
Oxygen therapy to stabilize blood oxygen levels
Nebulization and coupage to mobilize lung secretions
Intravenous antibiotics or antifungals
Continuous monitoring for respiratory fatigue
Early hospitalization significantly reduces mortality and long-term lung damage.
This is a condition where intervention timing directly impacts outcome.
Key Takeaway
Pneumonia is not an extension of a common cough—it is a life-threatening lung infection that demands veterinary diagnostics and, in many cases, inpatient care.
Persistent wet coughing, high fever, and severe lethargy are signals to act immediately, not observe.
A timely clinical evaluation can be the difference between recovery and respiratory failure.
