🐶🫁 Pulmonary Mineralization in Dogs: Causes, Symptoms & Treatments (2025 Guide) 🩺

By Dr Duncan Houston BVSc

Pulmonary mineralization, also known as calcium buildup in the lungs, is a condition where calcium deposits form within the lung tissues of dogs. This condition is more prevalent in older dogs and can range from asymptomatic to causing significant respiratory issues. Understanding the causes, recognizing the symptoms, and seeking appropriate treatment are crucial for maintaining your dog's health.

🧬 Causes of Pulmonary Mineralization

Several factors can lead to calcium deposits in the lungs:

• Age-Related Changes: As dogs age, calcium can accumulate in lung tissues without causing immediate health issues.
• Metabolic Disorders: Conditions like hyperadrenocorticism (Cushing's disease) can lead to mineralization due to hormonal imbalances.
• Inflammation or Injury: Previous lung infections or injuries can result in localized calcium deposits.
• Inhalation of Foreign Bodies: Breathing in foreign objects can cause lung irritation and subsequent calcification.
• Idiopathic Causes: In some cases, the exact cause remains unknown.

⚠️ Symptoms to Watch For

While some dogs may not exhibit noticeable symptoms, others may show signs such as:

• Persistent Coughing: A chronic cough that doesn't resolve over time.
• Labored Breathing: Difficulty in breathing or shortness of breath.
• Exercise Intolerance: Reduced stamina or reluctance to engage in physical activity.
• Cyanosis: A bluish tint to the gums or tongue, indicating oxygen deprivation.
• Rapid Breathing: An increased respiratory rate even at rest.

If your dog exhibits any of these symptoms, it's essential to consult your veterinarian promptly.

🩺 Diagnosing Pulmonary Mineralization

Veterinarians use a combination of methods to diagnose this condition:

• Physical Examination: Assessing the dog's overall health and respiratory function.
• Imaging: Chest X-rays or CT scans can reveal calcium deposits in the lungs.
• Blood Tests: Evaluating calcium and phosphorus levels, as well as checking for underlying metabolic disorders.
• Lung Biopsy: In some cases, a tissue sample may be necessary for definitive diagnosis.

💊 Treatment Options

Treatment depends on the severity and underlying cause:

• Monitoring: In asymptomatic cases, regular check-ups may be sufficient.
• Medications: Addressing underlying conditions like Cushing's disease with appropriate medications.
• Supportive Care: Providing oxygen therapy or bronchodilators to ease breathing difficulties.
• Surgical Intervention: Rarely, surgery may be required to remove localized calcium deposits.

Early detection and treatment can significantly improve your dog's quality of life.

🛡️ Preventive Measures

While not all cases are preventable, certain steps can reduce the risk:

• Regular Veterinary Check-ups: Routine exams can catch early signs of lung issues.
• Maintain a Healthy Diet: Ensuring balanced nutrition supports overall health.
• Prevent Inhalation Hazards: Keep your dog's environment free from small objects or toxins that could be inhaled.
• Manage Chronic Conditions: Properly treating conditions like Cushing's disease can prevent complications.
