How long are dogs pregnant?

Many new dog owners panic a little when they suspect their pup might be pregnant—wondering how long they have to prepare, what changes to expect, and if they’re doing everything right. It’s a common worry, especially if you’re new to caring for a pregnant dog, but knowing the basics can take a lot of the stress out of the process. The first question most people ask is about timing, and while there’s a general range, a few factors can affect how long your dog’s pregnancy lasts.

Scientifically, a dog’s pregnancy (called gestation) typically lasts between 58 and 68 days, with the average falling right around 63 days. That’s roughly two months—shorter than a human pregnancy, but still enough time to get ready for puppies. The variation in length often depends on the size of the litter; smaller litters might go a few days longer, while larger ones sometimes arrive a bit earlier. You might not notice many changes in the first few weeks, but around day 30, your vet can confirm the pregnancy with an ultrasound or blood test—this is also a good time to ask about diet and exercise adjustments.

Once you confirm the pregnancy, there are simple steps to keep your dog healthy. Start with their food: switch to a high-quality puppy food (yes, puppy food!) around week six, as it has extra calories and nutrients to support both mom and her growing puppies. Limit strenuous exercise—long runs or rough play can be risky—but keep up short, gentle walks to keep her active and maintain muscle tone. Create a quiet, cozy space for her to rest as the due date nears—think a soft bed in a low-traffic area, away from loud noises or other pets. Also, keep track of her behavior: if she starts nesting (gathering blankets or towels) or loses her appetite a day or two before due, labor is likely soon.

This is also a time to tie in responsible pet ownership habits you already follow. Just like you stay on top of regular vaccines (and your vet might recommend a booster for things like distemper during pregnancy) and clean up after her on walks, monitoring her health closely now is key. Avoid giving her any medications without vet approval—even over-the-counter ones can be harmful to puppies. If you live in an apartment, talk to your landlord ahead of time about having puppies, as some have rules about litters. And remember, spaying your dog if you don’t plan to breed her is one of the best ways to prevent unplanned pregnancies and protect her long-term health.

Caring for a pregnant dog is a special journey, and while it takes some extra effort, seeing healthy puppies and a happy mom makes it worth it. By knowing the typical gestation length, following your vet’s advice, and sticking to good care habits, you’ll be ready to support your dog every step of the way. Just take it one day at a time—soon enough, you’ll have a whole litter of tiny paws to love.
