Dog Pregnancy Calculator
If you are looking for a dog pregnancy calculator, let us first congratulate you on this new adventure!
I’m sure you are trying to figure out when your dog will be delivering her puppies.
Our canine pregnancy calculator makes it easy for you to get an idea when your dog should go into labor.
Keep in mind that this is not an exact calculation, but will give you a range of due dates.
You will simply enter the first date of your dog mating which will then give you an idea when to expect delivery of your new puppies.
Dog Pregnancy Calculator
Find out when your dog is due to deliver her puppies by entering the date of first mating below. This will give you an estimated date of delivery so you can be prepared.
Expected Due Dates
Estimated due date:
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?
Your dog will be pregnant for about 63 days on average.
Date of mating + 63 days = due date (2 months on average)
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.
How Do I Calculate A Dog’s Due Date?
Without using our calculator above you can easily figure out your dog’s due date by:
- Write down the date your dog mated. If you don’t know the exact mating date, you can make an educated guess.
- Get a calendar and add 63 days from that date. This will give you an idea of the approximate date you can expect to see new pups.
- Your dog’s delivery date can range from 58 days (on the lower end) up to 68 days (on the upper end), with some dog’s going to 70+ days. You will want to calculate this range from the mating date to give you a range of dates where you can expect your dog to deliver.
- Write these dates down in your calendar so you can be prepared for your dog’s labor and delivery.
- If you dog is past 70+ days, you may want to give your veterinarian a call.
Should Your Dog Get A 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.
Check out our top 7 signs of pregnancy in dogs to see if your pup is showing any of these signs.
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
You 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.
What To Watch For When The Time Arrives For Delivery
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.
Many people choose to get a whelping box, which is a safe box for their dog to deliver within.
Temperature Change Just Before Delivery
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.
You might notice your dog’s belly has hardened.
The uterus is now preparing to deliver the babies.
Your dog’s belly is probably also contracting as it gets closer to the actual delivery.
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 during delivery.
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.
Additional Pregnancy Tools:
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.
Want to follow along and know what pregnancy symptoms to expect on a week by week basis, then follow our dog pregnancy symptoms starting at week 1. We share information on what to expect for each of the 9 weeks of your dog’s pregnancy. The first few weeks, don’t expect too much to happen until at least week 4 of their pregnancy.
