Welcome to the new best dog pregnancy due date calculator. You can use this free tool to calculate your dog’s due date and when she will expect her litter of puppies. Add in the date of mating or the date of conception into the drop-down below.
Did you know?
The average dog pregnancy lasts 63 days. The shortest dog pregnancy usually lasts 57 days. A longer dog pregnancy will result typically in a gestation period of 65 days. The dog due date calculator above takes into account the date of mating and expected conception, rather than the ovulation date.
Dog due date calculator accuracy
It is hard to calculate a dog’s due date with complete accuracy as it varies within different breeds, often dependent on the size of the breed. Smaller breeds tend to have longer gestation periods than larger ones. For example, a Chihuahua’s average gestation period is 63 days while a Great Dane’s is only 58 days.
Knowing this can help you better predict when your puppy will arrive if you decide to get one of these two breeds. Generally speaking, toy breeds and large or giant-sized dogs take between 60 – 70 days for gestation, while medium-sized dogs can range from 57 – 69 days.
It’s important to keep in mind that due date accuracy also depends greatly on factors such as the dog’s health and nutrition during pregnancy, whether she was bred once or multiple times during the heat cycle, and even the weather during gestation.
Even if you did everything right when it comes to prenatal care, there can still be slight variations in due date accuracy based on these factors.
For this reason, it is best to keep track of your dog’s pregnancy and plan ahead for her due date by consulting with your veterinarian or a canine reproduction specialist. A dog due date calculator like the above can help to make things clearer.
Dog Pregnancy Calendar Week by Week
Week 1: During the first week of pregnancy, your dog’s body will start producing hormones to support the developing puppies. The lining of her uterus will begin to thicken in preparation for implantation.
Week 2: During this time, any fertilized eggs that have been released from the ovary will travel down the fallopian tube and into the uterus where they can be implanted in the thickened uterine lining.
Week 3: If your female dog is pregnant at this stage, then you may notice changes in her behavior and physical appearance as she begins to secrete milk due to hormonal changes. Her nipples may become darker and larger or swollen. You also might see a slight increase in appetite and some weight gain as well.
Week 4: During this time, your dog’s body will be producing more and more hormones in preparation for the puppies. This is also when you can start to feel her abdomen for fetal movement as well as measure an increase in her abdomen size.
Week 5: Your dog’s appetite should continue to increase and she may gain some additional weight. Her nipples may become even larger or darker than before due to the increased hormone levels. You may also see a decrease in activity level as she begins to conserve energy in preparation for delivering her puppies.
Week 6: At this stage, your pup’s uterus will be full of developing puppies and she will most likely be very uncomfortable. She may display nesting behaviors such as digging or searching out places that are warm and secure. You may also notice her becoming very protective of her abdomen, so it is important to be extra cautious when handling your pup during this time.
Week 7: During the seventh week of pregnancy, your dog will start to increase her food consumption as her metabolism begins to speed up. She may start showing signs of morning sickness and her nipples will become larger and darker in color. Her abdomen should begin to swell and you can feel the puppies move as they grow inside her. Your vet may recommend a diet change for your pregnant pooch, so that she is getting all the necessary nutrition for both herself and her growing puppies. It’s important to keep an eye on your pup’s weight during this time – too much weight gain could indicate health problems later on. Additionally, it’s important that she gets plenty of exercise in order to remain healthy throughout the pregnancy and delivery.
Week 8: At the eighth week of pregnancy, your dog will continue to increase her food intake and you may even need to adjust it again due to increased appetite. Her abdomen should be slightly larger as the puppies grow and develop. She may start having “nesting” behaviors such as digging in her bedding or carrying around toys. This is normal behavior for a pregnant pup – just make sure that she isn’t over-exerting herself or putting too much strain on her body. Additionally, if you notice any signs of labor such as panting, restlessness, licking her genitals, nesting behaviors or loss of appetite, contact your vet right away.
Week 9: During the ninth week of pregnancy your dog will gain weight quickly as her puppies grow inside her. She may appear uncomfortable and restless as the puppies begin to move more frequently. At this point, you should start getting everything ready for delivery – make sure you have a whelping box set up with soft bedding, plenty of food and water available, and be sure to inform your vet if you’re planning on having a home birth or need assistance with any problems that arise during labor. Additionally, keep an eye on your pup’s behavior and appearance – if she appears in distress or unwell contact your vet right away.
Week 10: In the tenth week of pregnancy your dog will reach full term – meaning she is now ready to deliver at any moment! At this stage all of her puppies should have developed and be ready for birth. All of her nipples should have darkened in color and become larger, and her abdomen should be quite large. Make sure that she has access to plenty of fresh water at all times and monitor her behavior closely – any signs of labor such as panting, restlessness or licking her genitals should be reported to your vet immediately. Additionally, keep an eye on the puppies movements – if they stop moving contact your vet right away as this could indicate a problem.
Week 11: During the eleventh week of pregnancy your dog may start going into labor at any time. Keep monitoring her carefully – any sign of contractions such as panting, restlessness or licking her genitals should be reported to your vetright away. Additionally, keep an eye on the puppies movements – if they stop moving contact your vet right away as this could indicate a problem. This is also the time to start preparing for delivery – make sure you have everything ready such as a whelping box with soft bedding, plenty of food and water available, and be sure that your vet will be on call in case any complications arise during labor.
To sum up
In summary, it’s important to keep an eye on your pregnant pup throughout her pregnancy by monitoring her behavior and weight gain, feeding her a nutritious diet, making sure she gets enough exercise and preparing for delivery. Don’t rest on your laurels once you have used a due date calculator.
Additionally, it’s vital to contact your vet right away if you notice any signs of labor or a decreased movement of the puppies. By taking all these steps, you can help ensure a healthy delivery for both your dog and her growing puppies.
