A dog's pregnancy lasts around 63 days, and knowing the due date helps you prepare for whelping with the right timing. Enter your dog's mating date into the Dog Pregnancy Calculator to get the expected due date, days remaining until birth, total gestation period, and your dog's current pregnancy stage.

Dog pregnancy is calculated by adding 63 days to the mating date. The gestation period for dogs typically lasts 58-68 days, with 63 days being the average. See also our Goat Gestation Calculator.
A dog is pregnant for approximately 2 months or 9 weeks. The exact duration is typically 58-68 days from the date of mating.
Early signs include decreased appetite, mild lethargy, and behavioral changes around 2-3 weeks after mating. A veterinary palpation test can confirm pregnancy at 28 days.
First litters typically have 1-5 puppies, though this varies greatly by breed size. Smaller breeds tend to have fewer puppies, while larger breeds may have more. You might also find our Chicken Incubation Calculator useful.
Add 63 days to the mating date to get the estimated due date. Keep in mind that delivery can occur anywhere from 58-68 days after mating.
Schedule a veterinary visit 3-4 weeks after mating to confirm pregnancy. Regular check-ups throughout pregnancy and preparations for whelping are recommended.
Switch to high-quality puppy food during the last third of pregnancy and while nursing. Increase food portions gradually as pregnancy progresses.
Prepare a quiet, comfortable whelping box 1-2 weeks before the due date. Have your vet's contact information ready and monitor for signs of labor.
