Calcium for Whelping Dogs
Support your dog through labour and lactation with the right calcium supplements. Learn when and how to supplement safely during whelping.
Why Calcium Is Crucial for Whelping Dogs
When it comes to whelping, proper nutrition plays a big role — and calcium is one of the most important minerals during this stage. It supports smooth muscle contractions during labour and prevents serious issues like eclampsia during lactation.
But supplementing calcium isn’t just about giving more — it’s about timing, dosage, and doing it safely. Here's what every breeder should know.
What Does Calcium Do During Whelping?
Calcium is essential for:
Uterine contractions during labour
Muscle control during birthing
Milk production once puppies are born
Low calcium levels during labour can lead to weak contractions and stalled labour. After birth, severe calcium deficiency can result in eclampsia (milk fever), a life-threatening emergency for nursing mums.
Should I Give Calcium Before Whelping?
No — and this is critical.
You should never give calcium supplements during pregnancy, especially the final few weeks. Doing so can reduce the dog’s natural ability to regulate her own calcium, increasing the risk of eclampsia after birth.
Instead:
Feed a balanced diet throughout pregnancy
Only begin calcium supplementation once active labour starts — and continue during lactation as needed
How to Supplement Calcium Safely
Once active pushing begins, you can start supplementing calcium. Popular options from our Calcium & Other Supplements Dog range include:
Fast-absorbing injectable calcium administered under veterinary guidance
Liquid calcium given orally such as Troy Calcium Syrup, Vetsense Calcium Syrup or Ossol Calcium and Vitamin Supplement.
Calcium powder such as Calci-D for use during lactation
Always follow the recommended dosage on the label or your vet’s advice.
Signs of Low Calcium (Eclampsia) in Nursing Dogs
Even with good feeding, some high-producing mums can experience calcium depletion. This most commonly occurs in small-breed dogs that are nursing large litters, especially at peak lactation, 2–3 weeks after whelping. Watch for signs of eclampsia, including:
Panting and restlessness
Muscle tremors or twitching
Stiff gait or difficulty walking
Seizures in advanced cases
Eclampsia is a veterinary emergency — immediate calcium treatment is needed.
Support for Mum Means Happier Pups
When the dam is nutritionally supported, puppies benefit too. Good calcium balance helps:
Efficient delivery
Steady milk supply
Less stress for mum — and fewer vet trips for you
It's a simple step that pays off in healthier, happier litters.
