Vet’s 2025 Guide to Retained Placenta in Dogs 🩺 Signs, Treatment & Recovery

By Dr. Duncan Houston BVSc

💡 What Is Retained Placenta?

A retained placenta (or retained afterbirth) happens when a dog's placenta isn’t expelled within ~15 minutes after each puppy is born. Residual placental tissue in the uterus can lead to infection (metritis) or life-threatening sepsis.

⚠️ Who Is at Risk?

Toy breeds, large litters, or difficult labor (dystocia) are more prone to retained placenta.
Weak uterine contractions (uterine inertia) or maternal fatigue also contribute.
Often overlooked if the mother eats the placenta, making counting challenging.

🚩 Clinical Signs to Watch

Greenish or foul-smelling vaginal discharge lasting > 24 hr postpartum.
Fever, lethargy, poor appetite, vomiting.
Poor maternal behavior or disinterest in nursing puppies.
Abdominal discomfort or swelling in advanced cases.

🧪 Diagnosis Steps

History, physical exam, and postpartum timing were noted by the owner.
Abdominal palpation may suggest retained tissue.
Diagnostic imaging—ultrasound or X-ray—confirms retained placenta or rules out retained puppies.
Bloodwork and vaginal cytology evaluate for infection or inflammation.

🩺 Treatment Protocols (2025)

1. Medical Treatment

Oxytocin within 24 hr postpartum stimulates uterine contractions and aids expulsion.
After 24 hr, prostaglandin F₂α or cloprostenol may be used if oxytocin fails.
Antibiotics (broad-spectrum) to treat or prevent metritis.
IV fluids and supportive care if systemic signs are present.

2. Surgical Intervention

Manual removal via exploratory surgery is required when medications fail or tissue becomes necrotic.
Ovariohysterectomy (spay) if future breeding isn't planned or severe uterine illness (metritis/sepsis) is present.

📅 Post-Treatment & Nursing Care

Monitor vaginal discharge in color and odor; should improve after expulsion.
Continue antibiotics and ensure hydration & nutrition.
Check temperature, energy, appetite, and maternal behaviors daily.
Pain control and uterine involution continue over ~2 weeks.
Follow-up ultrasound if discharge or signs persist to rule out subinvolution (SIPS).

📈 Prognosis & Risks

Early intervention → excellent outcomes; late cases risk metritis, sepsis, death.
Surgical removal/spay → fast recovery, low recurrence.
Untreated or delayed cases → uterine infection, systemic illness, or even death.

🚫 Prevention & Best Practices

Monitor whelping actively—count puppies and placentas when possible.
Ensure prompt veterinary intervention if green or foul discharge appears >24 hr postpartum.
Avoid elective spay immediately after birth unless medically necessary.
Consider uterine contraction support (oxytocin) at end of delivery.
Maintain a clean birthing environment and good hygiene for mother and puppies.

🔍 Key Takeaways

Retained placenta is rare but potentially fatal if untreated.
Green-foul discharge >24 hr postpartum, fever, lethargy are red flags.
Medical treatment with oxytocin and antibiotics works well early.
