A female dog's pregnancy typically lasts around 58 to 68 days.
This duration can vary depending on the breed and size of the dog.
Pregnancy Basics
Pregnancy in dogs can be confirmed through various tests performed by veterinarians.
Vets use a number of tests to diagnose pregnancy in dogs, including a physical examination and palpation of the abdomen.
A veterinarian can perform a pregnancy test to determine if a dog is pregnant, but it's usually done after the 28th day of pregnancy.
The test involves checking for fetal heartbeats and movement, which can be detected through an ultrasound.
A blood test can also be used to detect the presence of pregnancy hormones in the dog's blood.

Identifying Pregnancy
The most accurate way to tell if a dog is pregnant is through diagnostic testing. Your veterinarian can perform abdominal palpation starting at approximately the 28-30-day mark, where they'll feel the puppies like little golf balls or grapes depending on the size of the dog.
There are other methods to determine pregnancy, including ultrasound, hormone tests, and X-rays. An ultrasound can detect fetal heartbeats between 25 and 35 days of gestation, while X-rays are best done at 55 days or more to get an accurate count of the number of puppies.
Here are some signs of dog pregnancy you can watch for:
- Increase in appetite
- Weight gain
- Increase in nipple size
- Swollen belly
- Tires more easily
- Nesting behavior
- More affectionate
- Irritability
Keep in mind that some dogs may exhibit these signs but actually be experiencing a false pregnancy, or other conditions that can cause similar changes. To rule out a more serious condition, take your dog to the veterinarian for a checkup.
Am I Pregnant?
If you're wondering if your dog is pregnant, it can be a bit of a challenge to determine for certain. Unfortunately, there's no reliable laboratory test available.
Early pregnancy detection in dogs is extremely difficult, and veterinarians may use trans-abdominal palpation to check for an enlarged uterus around three to four weeks after mating. However, the results can be variable.
Abdominal ultrasound is currently the best method for detecting pregnancy, and with the right equipment, a positive diagnosis can be made as early as three weeks. Most scans from one month of pregnancy and onwards are reliable.
You should be cautious when estimating the number of puppies, as it can be difficult to accurately count the number of foetuses on an ultrasound.
Signs of Pregnancy
As you're trying to determine if your dog is pregnant, it's essential to know the signs to look out for. One of the most noticeable signs is an increase in appetite, which can start as early as a few weeks into the pregnancy.
Weight gain is another common sign, and it's usually noticeable around the same time as the increased appetite. However, it's not always a reliable indicator, as some dogs may gain weight for other reasons.
An increase in nipple size is a more specific sign, and it's often one of the first noticeable changes in a pregnant dog. This is because the nipples start to prepare for milk production.

A swollen belly is another obvious sign of pregnancy, and it's usually noticeable around the 28-30 day mark. However, it's essential to remember that a swollen belly can also be a sign of other health issues.
Some dogs may become more tired and tire more easily as their pregnancy progresses. This is due to the growing puppies and the increased energy requirements of the mother.
Nesting behavior is another common sign of pregnancy, and it's often seen in dogs that are preparing to give birth. This can include behaviors like digging and rearranging their surroundings.
Finally, some dogs may become more affectionate and clingy as their pregnancy progresses. However, this can also be a sign of other health issues, so it's essential to monitor your dog's behavior closely.
Here's a summary of the common signs of pregnancy in dogs:
Proper Nutrition
Proper Nutrition is crucial for a pregnant dog's health and the health of her puppies. A good quality dog food is essential, and if your dog is already on a good quality food and is at a healthy weight, you won't need to make any changes for the first two-thirds of her pregnancy.
A different take: Food for Pregnant Dogs
Increasing her food intake too soon can be harmful, so it's best to wait until her weight increases in the last weeks of her pregnancy. At this stage, veterinarians recommend increasing her food intake gradually, until she consumes 35-to-50 percent more than usual.
As her pregnancy progresses, her calorie needs will increase. To meet this need, you can increase her food intake by 30% to 50%. This means she'll be eating up to 50% more than her pre-pregnancy period.
To make mealtime easier for her, you can feed her small, frequent meals. This can help prevent discomfort and ensure she's getting the nutrients she needs. Alternatively, you can leave food down for her all day and let her eat at her own pace.
Here's a rough guide to her increasing food needs:
Keep in mind that every dog is different, and the best way to determine your dog's specific needs is to consult with your veterinarian. They can provide personalized advice and help you develop a nutrition plan that's tailored to your dog's unique needs.

Veterinary Care
Regular veterinary visits are crucial during pregnancy to ensure your dog stays healthy. You should take your dog to the vet for a prenatal checkup before breeding to make sure she's up-to-date on vaccinations.
Your vet will likely recommend a fecal exam or de-worming to prevent intestinal parasites. De-worming the pregnant dam with an appropriate medication starting on her third trimester can significantly decrease the amount of roundworm and hookworms in newborn puppies.
It's essential to set up a plan with your family and pet sitter in case of an emergency near the time of expected labor. Your vet will also examine your dog for any mechanical or anatomical concerns that could prevent a normal whelped litter.

Hormone Tests
Hormone Tests can be used to diagnose pregnancy in dogs.
To be accurate, hormone tests must be conducted at least 30 days into a dog's pregnancy.
The hormone Relaxin is released from the placenta tissue during pregnancy, making it a reliable indicator.
However, tests conducted before 30 days can produce false negatives, so it's essential to wait until the right time.
