Everything You Need to Know About Dog Pregnancy Tests

When your canine companion is expecting, it's essential to know as early as possible to provide her with the best care. Dog pregnancy tests are an effective way to confirm whether your dog is pregnant or not. In this article, we'll discuss everything you need to know about these tests, from their importance to different types and how to interpret the results.

Why Test for Dog Pregnancy?

Recognizing Signs of Pregnancy

It's not always easy to tell if your dog is pregnant just by observing her behavior. Some common signs include increased appetite, weight gain, and nesting behavior, but these can also occur for other reasons. By using a pregnancy test, you can confirm your suspicions and provide the appropriate care.

Importance of Prenatal Care

Prenatal care is vital to ensure the health of your dog and her puppies. Early detection of pregnancy allows you to adjust her diet, exercise, and monitor her health more closely.

Types of Dog Pregnancy Tests

Dog pregnancy test

There are several ways to test for dog pregnancy, each with its benefits and limitations.

Blood Test

A blood test can detect pregnancy by measuring the hormone relaxin, which is only produced during pregnancy. It's accurate and can be done as early as 22-27 days after breeding.


An ultrasound is a non-invasive procedure that uses sound waves to create an image of your dog's uterus. It can detect pregnancy as early as 21-30 days after breeding and can provide information about the number of puppies and their health.


An X-ray is another diagnostic tool that can detect pregnancy by revealing the puppies' skeletons. It's usually performed around day 45 of pregnancy, as the skeletons are not visible before this time.

How to Perform a Dog Pregnancy Test

Vet Assistance

The most reliable way to test for dog pregnancy is through a veterinarian. They can perform the blood test, ultrasound, or X-ray and provide expert advice on prenatal care.

At-Home Testing

At-home dog pregnancy tests are not currently available. While human pregnancy tests work by detecting a specific hormone, this method is not applicable to dogs, and using a human test will yield inaccurate results.

Interpreting the Results

Positive Results

A positive result indicates that your dog is pregnant. You should follow your veterinarian's advice regarding prenatal care, including diet, exercise, and any necessary supplements. Keep a close eye on your dog's health and maintain regular checkups to ensure a healthy pregnancy.

Negative Results

A negative result means that your dog is not pregnant. If you still suspect she may be pregnant due to her behavior or physical changes, consider retesting or consulting with your veterinarian. False negatives can occur, especially if the test is performed too early in the pregnancy.

Caring for Your Pregnant Dog


Proper nutrition is crucial during pregnancy to support your dog's health and the development of her puppies. Consult with your veterinarian to determine the appropriate diet, which may include switching to a higher-quality or specific pregnancy dog food. Gradually increase her food intake, particularly during the last trimester.


While exercise is essential for a healthy dog, you should adjust her routine during pregnancy. Regular, gentle exercise can help maintain her muscle tone and overall health.

When to Limit Activity

As your dog's pregnancy progresses, she may become less active and require shorter, less intense walks. It's essential to monitor her for signs of fatigue and adjust her exercise accordingly.

Preparing for Birth

As your dog's due date approaches, you should prepare a whelping box or area for her to give birth. This should be a quiet, comfortable space with soft bedding and easy access to food and water. Keep a close eye on her during the final days of pregnancy, and contact your veterinarian if you notice any complications or concerns.

Understanding dog pregnancy tests and how to care for your pregnant dog is essential to ensuring a healthy pregnancy and birth. By detecting pregnancy early, you can provide the appropriate care, including proper nutrition and exercise adjustments. Remember to consult with your veterinarian throughout the process and follow their expert advice.
