Introduction
Dog pregnancy, also known as canine gestation, is an exciting yet critical time for both the mother (dam) and her puppies. A dog’s pregnancy lasts approximately 58-68 days (around 9 weeks), and each stage requires specific care and monitoring to ensure a smooth whelping (birth) and healthy puppies.
This comprehensive guide will walk you through:
✅ The dog pregnancy timeline (week-by-week development)
✅ Whelping preparations and labor signs
✅ Essential post-birth puppy care
By understanding each phase, you can provide the best care for your expecting dog and her future litter.
Dog Pregnancy Timeline: Week-by-Week Development
Week 1-2: Fertilization & Early Development
What Happens?
- After mating, fertilization occurs in the fallopian tubes.
- The fertilized eggs travel to the uterus and begin cell division.
- No visible signs of pregnancy appear, but hormonal changes begin.
Care Tips:
✅ Continue regular feeding and exercise.
✅ Avoid any medications unless prescribed by a vet.
✅ Reduce stress and monitor for changes in behavior.
Week 3-4: Embryo Implantation & Early Symptoms
What Happens?
- Around day 18-20, the embryos attach to the uterine lining.
- Hormonal shifts may cause morning sickness (vomiting or loss of appetite).
- The dam may become more affectionate or slightly lethargic.
Care Tips:
✅ Offer smaller, frequent meals if morning sickness occurs.
✅ Schedule a veterinary checkup around day 25 for ultrasound confirmation.
✅ Begin transitioning to high-calorie puppy food.
Week 5: Noticeable Physical Changes & Fetal Growth
What Happens?
- The fetuses develop major organs, facial features, and limbs.
- The dam’s abdomen slightly enlarges, and her nipples darken.
- She may experience an increase in appetite.
Care Tips:
✅ Feed high-quality puppy food for extra nutrition.
✅ Reduce vigorous exercise, but maintain gentle walks.
✅ Avoid handling her belly excessively to protect the growing fetuses.
Week 6: Rapid Growth & Weight Gain
What Happens?
- The fetuses develop bones, claws, and whiskers.
- The mother’s abdomen noticeably expands.
- She may show nesting behaviors (digging, carrying soft objects).
Care Tips:
✅ Provide a comfortable nesting area in a quiet space.
✅ Increase meal portions to support fetal growth.
✅ Start monitoring for mood changes (protective behavior).
Week 7: Preparing for Labor
What Happens?
- The puppies are now almost fully developed.
- The mother’s appetite may decrease as pressure on her stomach increases.
- Her mammary glands swell, and she may begin producing milk.
Care Tips:
✅ Set up a whelping box with soft bedding.
✅ Reduce stress—avoid introducing new pets or guests.
✅ Continue feeding puppy food and ensure she stays hydrated.
Week 8-9: Final Stages & Whelping Preparation
What Happens?
- The puppies move into birthing position.
- The dam may appear restless, pant more, or seek isolation.
- Labor typically begins between days 58-68.
Care Tips:
✅ Monitor for early signs of labor (panting, pacing, temperature drop).
✅ Keep a whelping kit ready (towels, gloves, clean scissors).
✅ Contact a vet if labor exceeds 24 hours or she appears in distress.
Signs of Labor in Dogs & Whelping Process
Stage 1: Pre-Labor (6-24 Hours Before Birth)
🔹 Signs:
- Drop in body temperature (below 99°F / 37.2°C)
- Restlessness, nesting behavior
- Shivering, panting, or vomiting
🔹 What to Do:
✅ Keep the dam comfortable in her whelping box.
✅ Monitor her temperature every few hours.
✅ Keep food and water available, but expect low appetite.
Stage 2: Active Labor & Delivery (2-12 Hours)
🔹 Signs:
- Strong contractions begin.
- Fluid sac breaks, and the first puppy is delivered within 30-60 minutes.
- Each puppy follows every 30-60 minutes, with resting periods.
🔹 What to Do:
✅ Allow the mother to clean each puppy naturally.
✅ If she struggles, break the sac and clear airways with a clean towel.
✅ Contact a vet if a puppy is stuck for more than 1 hour.
Stage 3: Placenta Delivery & Aftercare
🔹 Signs:
- The placenta is expelled after each puppy.
- The mother may eat the placenta (normal behavior).
🔹 What to Do:
✅ Count the placentas—each puppy should have one.
✅ Dispose of excess placenta if not consumed.
✅ Provide the dam with fresh water and food after delivery.
Newborn Puppy Care: First Few Weeks
Week 1-2: Immediate Post-Birth Care
✅ Ensure puppies stay warm (around 85-90°F / 29-32°C).
✅ Puppies should nurse every 2 hours for proper nutrition.
✅ Monitor for weak or rejected puppies (may need bottle feeding).
Week 3-4: Weaning & First Steps
✅ Start introducing soft puppy food mixed with warm water.
✅ Puppies begin walking and playing—ensure a safe environment.
✅ First deworming treatment is recommended.
Week 5-8: Socialization & Vet Checkups
✅ Gradually transition to solid puppy food.
✅ Schedule first vaccinations (6-8 weeks old).
✅ Begin basic training and socialization.

⚠️ Eclampsia (Low Calcium): Weakness, tremors, or seizures—seek emergency vet care.
⚠️ Stillborn Puppies: Remove immediately and monitor for any signs of infection.
⚠️ Fading Puppy Syndrome: Puppies not nursing or gaining weight—may need vet intervention.
