Dog Gestation Period Calculator – Dog due date calculator

The first step in calculating dog pregnancy is determining the gestation period. On average, dogs are pregnant for about 63 days, which is approximately two months. However, it’s essential to remember that nature doesn’t always adhere to strict rules, and the gestation period can vary between 58 and 68 days.

How do I calculate my dog’s pregnancy? – dog due date calculator

calculate dog pregnancy

You can use the following calculation to determine your dog’s due date:

Due date = Date of mating + 63 days

Your vet can confirm pregnancy roughly 28 days after breeding by performing a palpation test if you know the precise date of mating. If you need clarification on the mating date, your veterinarian can estimate the gestational age and due date by performing a simple and painless ultrasound check.

Also, an X-ray can be performed to visualize the puppies as the gestational process progresses. However, at the early stages of pregnancy, the puppies may not be visible due to their low level of ossification.

Bringing a litter of puppies into the world is an exciting and joyous time for any dog owner. While diagnostic testing is the most reliable method to confirm pregnancy, there are also noticeable signs you can watch out for.

Weeks 1 and 2: The Calm Before the Storm

Most dogs won’t display any noticeable symptoms during the first two weeks after conception. Their weight remains stable and might seem just as energetic as usual. However, some dogs may start experiencing mild morning sickness, which could lead to sporadic vomiting or changes in appetite.

Week 3: Appetite and Nipple Changes

Around the third week, you might notice an increase in your dog’s appetite. Her nipples may become slightly enlarged and may take on a darker hue. Additionally, you might observe more affectionate behavior from your furry friend.

Week 4: Physical Changes Begin

As you enter week four, your dog’s physical activity might decrease. Clear vaginal discharge could be noticed during this time. It’s recommended to schedule a vet appointment for an ultrasound around this week to confirm the pregnancy and check on the developing puppies.

Week 5: Weight Gain and Behavioral Shifts

During week five, your dog’s weight gain becomes more noticeable. Increased urination could become apparent, and you may begin to observe behavioral changes as your dog’s body adjusts to the pregnancy.

Week 6: Puppies on the Move

By the sixth week, your dog’s abdomen might enlarge and be firm. This is a thrilling stage as you might be able to feel and witness puppy movement. Some dogs might experience a loss of appetite, so consider providing smaller meals throughout the day to ensure proper nourishment.

Week 7: Preparing for Birth

Appetite loss could persist into the seventh week. The output of the waste (urine and feces) might become slimmer as the puppies enter the birth canal. This is an excellent time to start setting up a comfortable whelping box for the upcoming delivery.

Week 8: Lactation Begins

Around week eight, your dog may start producing milk, preparing her body for the imminent arrival of her puppies.

Week 9: The Final Countdown

As your dog approaches week nine, she’ll likely become restless and irritable. This restlessness could be due to the impending labor. Keep an eye on her body temperature; a drop in body temperature shortly before labor begins is a common indicator.

A Labrador Retriever’s pregnancy, or gestation period, typically lasts around 63 days. This period can vary between 57-65 days, with planned breeding and accurate mating dates important for predicting birth, usually occurring between 63-65 days after mating.

Factors Affecting the Number of Puppies

Dog pregnancy

Several factors can influence the number of puppies your dog will have, including:

1. Breed of the dog

Larger dogs tend to have larger litter, typically ranging from 8 to 12 puppies. On the other hand, smaller dogs usually have smaller litters, averaging around 1 to 4 puppies.

2. Amount of the male’s sperm

The quantity of sperm plays a role in fertilization, and a higher number of healthy sperm can increase the chances of a larger litter.

3. Breeding time

The timing of breeding within the female’s heat cycle can also impact the number of puppies. The female dog is most fertile during her second or third heat, which occurs every 5 to 11 months.

4. The health of the female

The pregnant dog’s overall health can affect the litter’s size. A healthy and well-nourished mother is more likely to have a larger litter.

5. The state of the dog’s uterus

Previous pregnancies and the condition of the dog’s uterus can influence the number of puppies.

How early can a dog give birth?

Dogs typically give birth after a gestation period of around 63 days, which is approximately two months. However, dogs can give birth earlier than the ideal 60 days of gestation. Preterm delivery in dogs is defined as a birth that occurs before the expected due date.

Puppies born at 58 days of gestation or later have a higher chance of survival. This is because, by this stage of development, the puppies have reached a point where their vital organs and systems are more developed, increasing their ability to survive outside the womb.

Preparing for Labor and Delivery

As the due date approaches, preparing for the labor and delivery process is crucial. Once you have used a dog pregnancy calculator to determine the labor date, there are a few essential items you should have on hand:

  • Sterile gloves will help ensure a hygienic environment during the birthing process.
  • Sterilized scissors: In some cases, you may need to cut the puppies’ umbilical cords. Make sure the scissors are properly sterilized to prevent infection.
  • A bottle with the prepared formula: While most puppies will nurse from their mother, it’s a good idea to have a bottle with prepared formula in case supplemental feeding becomes necessary.

Labor can last anywhere from 12 to 60 hours, so it’s important to be patient and support your dog throughout the process.

Your dog’s temperature will drop by around 1.8°F, and she may display signs of restlessness, increased thirst, and rapid breathing. Many dogs will also gather their toys and seek out a quiet, safe place to give birth.

Taking Care of Your Pregnant Dog and Puppies

During your dog’s pregnancy, it’s crucial to provide proper care to ensure the well-being of both the mother and her puppies. Here are some important considerations:

1. Avoid certain medications

Some medications, including certain antibiotics or antifungal treatments, may harm pregnant dogs. Inform your veterinarian about the pregnancy to avoid any potential risks.

2. Monitor food intake

Your pregnant dog will require a higher caloric intake as the pregnancy progresses. Starting from the second month of gestation, she should consume around 20-25% more food than usual. By the end of the pregnancy, this amount should increase to approximately 50%. During lactation, her food intake should double compared to her pre-pregnancy amount.

3. Puppies’ development

Puppies typically start to open their eyes around 8-10 days after birth. However, their vision is still developing, and they can only discriminate between shapes around the 18th day of their lives if they encounter difficulties while nursing, gently guiding them to their mother’s nipples, as they will instinctively know what to do once they find them.

FAQs on Dog Prangnency

Is it OK for a 1-year-old dog to get pregnant?

No, it is generally not recommended for a 1-year-old dog to get pregnant. The best age for a dog to get pregnant depends on when she reaches sexual maturity, which can vary between breeds. Smaller breeds may reach sexual maturity as early as four months, while larger breeds may need to wait until they are around two years old.  

What does a 7-week pregnant dog look like?

During the seventh week of pregnancy, a dog will show visible signs of pregnancy. Here’s what you can expect:

  • Swollen breast tissue: Your dog’s breast tissue will become swollen as her body prepares for nursing. You may notice that her nipples are prominent and dark in color.
  • Colostrum leakage: Your dog may have a cloudy fluid called colostrum leaking from her nipples. This is often referred to as “first milk” and provides essential nutrients to the newborn puppies.
  • Shedding of belly hair: Your dog may start to shed the hair from her belly as her body undergoes changes to accommodate the growing puppies.
  • Movement of fetuses: At this stage, you may be able to see and feel the fetuses moving beneath her skin. This is an exciting sign of the puppies’ development.

Can a dog give birth at 52 days?

No, it is unlikely for a dog to give birth at 52 days. The normal gestation period for female dogs is around 63 days, although it can vary slightly depending on the breed. Smaller dogs tend to give birth a little earlier, typically between 56 to 69 days.

So, if a dog is at 52 days of pregnancy, it is still a bit early for her to deliver the puppies.

Is it OK for a 1-year-old dog to get pregnant?

It is not recommended for a 1-year-old dog to get pregnant. Dogs should be matured before getting pregnant and breeding to avoid potential behavioral or physical problems. It’s best to let your dog have a chance to grow up first.

Nowadays, you can purchase home pregnancy tests for dogs, such as Witness Relaxin, online. These tests can be performed as early as 20-21 days after the luteinizing hormonal surge to determine if your pet is pregnant.

No, a whopping 40% of female dogs will fall pregnant after just one mating session. However, there are ways to prevent pregnancy after mating to avoid having a litter of unwanted puppies.

Do pregnant dogs drink a lot of water?

Yes, a pregnant dog’s thirst is exacerbated, and she may drink more water than usual because her body needs it during pregnancy and nursing. This is especially common when temperatures are higher, such as in the summer or early spring.
