Dog Pregnancy Week‑by‑Week: Complete Timeline & Stages
Follow your dog's journey from mating to whelping. Understand the dog gestation period (58–68 days), early signs, and how to care for your pregnant dog.
🐾 Week‑by‑Week Pregnancy Timeline
The average dog pregnancy calendar spans 9 weeks. Each week brings new changes for the mother and her developing puppies.
Week 1‑2: Fertilization & Early Cell Division
The sperm meets the egg. Fertilized eggs travel to the uterus. No outward signs of pregnancy are visible yet.
- Mating occurs; sperm can live up to 7 days inside the female.
- Eggs are fertilized in the oviducts.
- Early embryo development begins silently.
- No changes in appetite or behavior noticed.
Week 3‑4: Implantation & Early Signs
Embryos attach to the uterine wall. This is when the first subtle early signs of dog pregnancy may appear.
- Embryos implant around day 18–21.
- Possible decreased appetite or mild nausea.
- Nipples may begin to enlarge and pinken.
- Some dogs become more affectionate or withdrawn.
- A vet can confirm pregnancy via ultrasound around day 25–30.
Week 5‑6: Visible Belly & Rapid Growth
Physical changes become noticeable. Your dog's belly swells, and weight gain accelerates.
- Abdomen visibly enlarges.
- Nipples darken and may produce clear fluid.
- Appetite increases – switch to small, frequent meals.
- Puppies start developing limbs, claws, and organs.
- Exercise should be gentle, avoid rough play.
Week 7‑8: Nesting & Final Growth
Foetal development speeds up. The mother may start nesting, and milk production begins.
- Puppies gain most of their birth weight.
- Dog becomes restless, may scratch bedding.
- Prepare a whelping box in a quiet, warm area.
- Start taking her temperature daily; a drop below 37.8°C (100°F) signals labour within 24 hours.
- Avoid stressful situations and loud noises.
Week 9: Whelping & Delivery
Puppies are fully developed and ready to be born. Labour can start any time now.
- Dog may pant, shiver, or refuse food.
- Body temperature drops 12‑24 hours before labour.
- Have vet emergency number ready.
- Stay calm and monitor; most deliveries proceed naturally.
- After birth, ensure puppies nurse within the first hours.
