About Canine Pregnancy

A dog's pregnancy (gestation period) typically lasts about 63 days (9 weeks) from conception, though this can vary slightly depending on the breed and litter size.

Pregnancy Stages
  • Weeks 1-3: Early development - fertilised eggs travel to the uterine horns and implant in the uterine lining.
  • Weeks 4-5: Middle stage - puppies begin to develop distinct features and the mother's belly starts to enlarge.
  • Weeks 6-9: Late stage - rapid puppy growth, mother's preparation for birth, and eventual whelping.
Signs of Pregnancy in Dogs
  • Increased appetite (first few weeks)
  • Slightly enlarged nipples and darker nipple colour
  • Clear vaginal discharge (without odour)
  • Increased weight and abdominal enlargement (from week 4-5)
  • Decreased appetite in later stages as puppies crowd internal organs
  • Nesting behaviour in the final week
Preparing for Whelping

As the due date approaches, prepare a whelping box in a quiet, low-traffic area of your home. Monitor your dog's temperature - a drop below 37.8°C (100°F) often indicates labour will begin within 24 hours. Look for signs like restlessness, nesting, and loss of appetite that indicate labour is imminent.

Understanding Dog Gestation Timeline
