Veterinary Guide to Eclampsia in Dogs (Milk Fever) 2025 🐶🩺

By Dr. Duncan Houston BVSc

🔍 Introduction

Eclampsia—also known as puerperal tetany or milk fever—is a life-threatening drop in blood calcium in pregnant or nursing dogs. As a veterinarian, I want you to recognize early signs, get emergency care, and safeguard your canine moms in 2025. ⚠️👩⚕️

💡 What Is Eclampsia?

The condition arises from severe hypocalcemia due to high calcium demand from fetal development or milk production, especially 1–4 weeks postpartum. Small breeds and large litters are at particular risk.

🚨 Clinical Signs

• Early signs: restlessness, panting, pacing, drooling
• Progresses to: stiff gait, muscle tremors, high fever, increased heart rate
• Severe cases: seizures, collapse, coma—urgent veterinary care essential

🏥 Diagnosis & Emergency Intervention

• History of nursing and clinical signs prompt suspicion
• Confirm via blood tests showing serum calcium <7 mg/dL
• Monitor heart and electrolytes (ECG, blood glucose)

🛠 Treatment Protocols

Immediate Care

• IV calcium gluconate administered slowly with cardiac monitoring
• IV fluids to restore hydration and electrolytes
• Anti-seizure medication (e.g., diazepam) for convulsions

Follow-Up & Home Care

• Oral calcium and vitamin D supplements as directed
• Weaning pups: separate temporarily (12–24 h) to reduce calcium drain, start milk replacer or puppy food
• Repeat bloodwork to ensure stable calcium levels

📈 Recovery & Prognosis

With fast treatment, most dogs rebound quickly, often within hours. However, there's ~20% risk of recurrence in future litters if management isn’t adjusted.

🛡️ Prevention Strategies

• Feed a premium, balanced diet formulated for pregnancy/lactation
• Avoid calcium supplementation during gestation; it may suppress parathyroid response
• Monitor high-risk dogs (small breeds, large litters) closely—consider periodic blood calcium testing
• Wean puppies at 3–4 weeks to reduce maternal calcium demand
