Eclampsia in Dogs
What Is Eclampsia in Dogs?
Eclampsia in dogs, also known as milk fever, is a sudden drop in blood calcium levels. It occurs most often in small-breed mothers during peak lactation, usually one to three weeks after whelping.
This condition is life-threatening and demands fast treatment. Without intervention, seizures, coma, or death can follow in hours.
What Causes Eclampsia in Dogs?
Lactating females require extra calcium to produce milk. If their body cannot keep up with demand, blood calcium plummets. This disrupts nerve and muscle function.
Risk factors include:
- Small breed size (e.g., Toy Poodles, Chihuahuas)
- Large litter sizes
- First-time mothers
- Inadequate nutrition
- Supplementing with calcium before birth (which can suppress natural regulation)
Signs of Eclampsia in Dogs
Eclampsia develops fast. Early signs may be subtle but can escalate within minutes. Look for:
- Panting or restlessness
- Trembling or muscle twitching
- Pacing or disorientation
- Stiff legs or difficulty walking
- Fever
- Seizures
- Collapse
If you see any of these signs in a nursing mother, treat it as an emergency.
What Should Breeders Do If They Suspect Eclampsia in Dogs?
- Contact a vet immediately – Don’t wait. This condition can worsen quickly.
- Keep the dam calm and cool – Reduce stimulation and provide a quiet space.
- Separate puppies from the mother – Bottle feed until the dam stabilises.
- Provide calcium treatment – Only under veterinary guidance.
Early veterinary care often involves intravenous calcium, followed by oral supplements and monitoring.
Prevention Tips for Breeders
Feed a high-quality diet during pregnancy and lactation. RPBA offers nutrition guides for members.
Avoid calcium supplements during pregnancy unless directed by a vet. Over-supplementation can interfere with natural calcium regulation.
Weigh litters daily – Large, fast-growing litters place more strain on the dam.
Support the mother with additional meals during peak lactation.
Monitor for early signs – Catching the condition early is vital.
Can the Puppies Continue Nursing?
Once the mother is stable, she may return to nursing under supervision. If not, breeders must supplement with formula.

Frequently Asked Questions About Eclampsia in Dogs
When does eclampsia usually occur?
Most cases develop one to three weeks after whelping, when lactation demand is highest.
Can eclampsia be fatal?
Yes. Without fast treatment, it can lead to seizures, coma, and death.
Should I give calcium supplements during pregnancy?
No. This can suppress the dam’s ability to regulate calcium naturally. Supplement only after birth and under veterinary advice.
Which breeds are most at risk?
Toy and small breeds are more vulnerable, especially with large litters.
Can a dam nurse again after recovery?
Sometimes. With vet guidance and calcium support, some dogs can resume nursing safely.
What’s the long-term outlook after eclampsia?
Many dogs recover fully, but the risk of recurrence is high in future litters. Spaying may be recommended after recovery.
How can I feed the puppies if the dam can’t nurse?
Use a canine milk replacer. RPBA has options for milk replacer on the RPBA shop.
