The estimated due date of your dog's pregnancy is 63 days. This is the average length of gestation in dogs. The date above shows an estimation of the earliest and latest dates for delivery. Your dates may vary. Contact your local veterinarian if you have questions.

How Long Do Dogs Stay Pregnant?

Canine Pregnancy CalculatorYour dog will be pregnant for about 63 days. This is the average amount of time from conception to delivery that dogs will be pregnant. People often search for how long dogs are pregnant in weeks, which is 9 weeks. This will allow you to schedule your life around this big change that is coming to your life. Mark the due date on your calendar so you know when you need to be prepared. The average gestation period of a female dog will range between 58 to 68 days (roughly 8-10 weeks).

Now that your canine is pregnant you will need to be more proactive with their feeding schedule, making sure you stay up to date with their pregnancy and be prepared for the big day when it arrives.

Based on the calculation above, your canine will be delivering within 63 days.

The estimated due date is 63 days from the first mating, which is the length of gestation in canines. The expected dates indicate the earliest and latest expected dates of delivery. Dates may vary in some instances.

Should You Get A Dog Pregnancy Ultrasound?

If you have no idea when your dog mated, but you know she is pregnant, then an ultrasound may be worth the cost. A dog pregnancy ultrasound costs between $300-$500. This price can be completely different depending on where you live so be sure to call your local vet for their pricing.

If you have doubts about your dog’s pregnancy you can always call your local vet or schedule an appointment with them. They may give you guidance and help you through this process. Talking with them will also help relieve any stress you might have about the situation.

Another reason you might want to get an ultrasound is to find out how many pups you should expect to have.

How You Can Estimate Your Dog’s Due Date

We know that your female dog will be pregnant for anywhere from 58 days to 68 days, or about two months. If you have no idea when your dog first mated, you can try to guess the time frame. For example, our black lab used to get out of our backyard, she would run down the street and come home. Knowing she got out a few times we can easily guess when she may have first mated. That gave us a good idea of a due date when we found out she was pregnant.

As a general rule, put in the first date you think your dog mated into our canine pregnancy calculator above. That will give you at least a time frame to watch and to be prepared. By knowing when your dog will deliver you can then follow our dog pregnancy calendar to keep track of your dog’s progress through the pregnancy.

If you have doubts about an estimated delivery date, then we suggest consulting with your local veterinarian. Remember, they will be a huge resource for you, they have the knowledge and expertise to help guide you through this process.

Preparing For Your Dog’s Delivery Date

Labrador with her new puppies after being pregnant for 63 daysYou want to be ready for the delivery date well before it arrives. Being prepared can be the difference between life and death of your dog and her pups. In most cases dogs will deliver without any problems and without the need for assistance. Your job will be to provide food, water and a clean (and calm) area for your dog to deliver her pups.

Here are a few things to watch for when the time arrives:

  • Whelping – This is an indication that the delivery date is almost here. Your dog might start acting odd or confused. She will start to nest or start to look for a quiet area where she will deliver her pups. In pregnant women we usually say “you’re nesting” when it’s close to their due date. That is a natural instinct with females when the time for delivering is close. Dogs will do the same thing, so do not be caught off guard. Some canines will want you to be present, may stick close to you while others might hide or want to be left alone. If you are looking for a whelping calculator, it is the same thing as our calculator above. The terms “whelping calculator” and “canine pregnancy calculator” are the same thing. It is a calculation of when labor and birth should start.
  • Temperature – You can measure your dog’s body temperature to see if she is in labor. Your vet might have you monitor your dog’s body temperature for days before the delivery date to get a baseline temp. Normal rectal temperatures range between 101-102 degrees. Right before labor starts your dog’s temperature will drop to just below 100 degrees. This is an indication that delivery will most likely occur within the next 24-hours.
  • Belly Changes – You might notice your dog’s belly has hardened.

Your Dog’s Pregnancy Length Explained

It might be confusing to see a wide range of dates, but just like humans the actual delivery date is just an estimation. Your dog’s pregnancy length will range between 58 days and up to 68 days. Some dogs may go into labor early while others may take their time and reach 70 days from gestation. Depending on how early or how late your dog is, you might want to give your local vet a call so they can help monitor the health of the pregnancy.

You can be prepared by talking with your veterinarian during this time. Have a plan put into place in case of emergency. Most dogs will deliver without problems, but some might require help. You can talk with your veterinarian to see if your breed of dog might be at higher risk for complications.

Just like a dog’s pregnancy, a cat’s pregnancy length is similar. We have created a Cat Pregnancy Calculator for those who want to know when they can expect their new kittens to arrive.

    My dog’s mate date was February 1, 2020. She hardly has any stomach just her pouches. Can she be pregnant?

    • Leslie at 10:30 am

      Hi Maira, based on our dog pregnancy calculator your dog would be due between March 31 – April 6. If your dog has not delivered by April 6, I would encourage you to contact your local veterinary. They will most likely want to do an exam and possibly an xray if they find it is needed. Your question is difficult to answer without seeing your puppy in person which is why its always safe to contact your local vet.

    Hi, my dog’s mate date was on February 10th and scan done at around 35 days. The vet confirmed pregnancy and due date on April 15th, today. Nothing is happening. Should I be worried?

    • Leslie at 2:51 pm

      Hi Marta, congrats to the soon to be mom! With all pregnancies, due dates are just estimations. Even though the average gestation of a dog is 63 days your dog can stay pregnant for up to 70 days. Just like with a human, some are born later beyond their due dates. If your dog is at 63 days today you should give her more time. Over the next few days try to observer her behavior. Is she being more clingy or is she hiding. Does she have a quiet and clean area to give birth? The next few days I’m sure you will see a change in her behavior as the labor process kicks in. If for some reason she hasn’t delivered by day 68-70, give your local vet a call.

    Hello, my dog mated (unintentionally) February 23. I have her delivery date around this coming Thursday. Yesterday, She started licking herself excessively and having a watery/bloody, smelly discharge yesterday. She’s drinking water but hasn’t really eaten much since then. Is this normal? Everything I’ve read says it’s signs she’s going into labor, except the smell. Everything is closed right now since it’s the weekend. She’s 8 1/2 years old and her first pregnancy.

    • Leslie at 9:41 am

      Hi Chris, sounds like all of the signs of delivery are there. If anything does go wrong and its the weekend there are always animal hospitals that are open 24/7. You can always call one of them if you have questions.

  • Taylor Cheyenne Watson at 12:44 am

    My dog got pregnant approximately February 11, 2020. Her belly is gigantic and she is growing fine. Her due date was April 16, 2020. She has still not given birth. Should I be concerned?

    • Leslie at 9:46 am

      Hi Taylor – Due dates are a range of days based on the average gestation period. So the actual date could be +/-5 days. It is hard to say if you should be concerned without knowing more to your story. Was the pregnancy confirmed with an ultrasound? Did your vet give you a due date based on their calculation? The best thing you can do is call your local vet. Depending on your history with them, they might have you come in with your dog so they can do a physical evaluation.
