A Comprehensive Guide to Dog Pregnancy Tests and At-Home Pregnancy Test Options


Do dogs have a pregnancy test? Do tests for dog pregnancy work on dogs? Do human pregnancy tests work for dogs? At-home dog pregnancy tests? 

We will go into the topic of dog pregnancy in this extensive article, covering symptoms, duration, test efficacy, and much more. 

Is there a pregnancy test for Dogs? 

The only pregnancy test that can be performed on dogs is the one that looks for the hormone relaxin, which is only present 22 to 27 days after the embryo is implanted (i.e. when the dog is typically 4 weeks pregnant). 

These pregnancy tests are effective for canines and can also be fairly accurate, given that relaxin levels stay high for most of the dog's pregnancy and only start to drop after it ends, according to VCA Animal Hospitals. 

However, because blood must be drawn and either separated from the serum using a centrifuge (because plasma is required) or taken to the veterinarian, this pregnancy test is difficult for dog owners to administer. 

Do dog pregnancy tests work on dogs? 

Indeed, dog pregnancy tests are made especially for use with dogs. These tests look for the hormone relaxin, which is produced by the developing placenta soon after implantation, in the dog's urine. These tests offer a trustworthy way to determine whether a dog is pregnant by measuring relaxin levels. Pet owners can utilize them conveniently in the comfort of their own homes because they are generally available. Dog pregnancy tests are a useful tool for detecting pregnancy in dogs because of their accuracy and simplicity of use. 

At-home dog pregnancy test 

Home dog pregnancy tests are a convenient and accessible way for pet owners and breeders to confirm pregnancies. The Whelply Canine Pregnancy Test offers a blood-based substitute without the need for expensive equipment, while the GOYOJO Ultrasound Scanner confirms pregnancy early and continuously monitors fetal viability. The Bellylabs Pregnancy Test for Dogs is particularly notable for its ease of use—it just needs a drop of blood, and yields results in ten minutes. With tests that meet various needs, dog breeders and owners can confirm dog pregnancies from the comfort of their own homes with flexibility. 

Pregnancy tests for Dogs: 

It's critical to get in touch with your veterinarian as soon as you suspect a dog is pregnant. Veterinarians use ultrasounds, x-rays, belly palpation, and relaxin dog pregnancy tests among other techniques to verify pregnancy.  

  1. Dog Pregnancy Test for Relaxin: This blood test analyses the levels of relaxin hormone generated by the growing placenta and can be used as early as 22 days after conception. If done too early, though, it can result in false negatives, requiring further testing.  

  1. Ultrasound: Known as the gold standard, abdominal ultrasound evaluates fetal viability and litter size in addition to early pregnancy confirmation. 

  1. Abdominal Palpation: This age-old, less accurate technique finds the uterine swellings of puppies, but only after about 30 days of pregnancy. It is unreliable for detecting fetal viability or count, and it could be difficult with large breeds or anxious dogs.  

  1. X-rays: When taken later in pregnancy (about 55 days post-conception), x-rays can accurately determine the number of litters.  

Although the accuracy of each approach varies and there are cost and schedule constraints, they all provide insights into verifying dog pregnancy. 


How to detect Early Pregnancy in Dogs 

Pet owners who are concerned about early pregnancy in dogs have a few alternatives. First, approximately 28 days into a pregnancy, a veterinarian can palpate the abdomen to detect the presence of puppies; however, because of the risk of injury from harsh handling, this procedure is better left to professionals. Another way to find puppies is via X-ray, which is usually done 42–50 days after mating. However, the number can't always be accurately determined until about day 55. Contrarily, ultrasounds yield trustworthy and non-invasive data; the greatest results are typically seen around day 30 of pregnancy. Even though fetal heartbeats can be seen with ultrasound, it's not always possible to pinpoint the precise number of puppies. 

On the other hand, a natural strategy is to wait for the progression of pregnancy symptoms. Puppies are normally born 57 to 64 days after breeding, with an average gestation period of 63 days. Due to hormonal variations, human pregnancy tests are not appropriate for dogs; nonetheless, pregnancy in dogs can be successfully confirmed by techniques like palpation, relaxin tests, x-rays, or ultrasounds. For peace of mind and the right care, pet owners can select the approach that best suits their tastes and the stage of their dog's pregnancy.  


Dog pregnancy symptoms week 1 

Not all dogs show early symptoms, and the early warning signs of dog pregnancy can be inconspicuous.  


  • appetite decline  

  • morning sickness, or vomiting  

  • Diminished vitality  

  • swollen nipples  

  • clear discharge from the vagina  

  • Greater displays of affection  

Pregnancy signs in dogs include weight gain, increased appetite, and behavioral changes like irritation or nesting behavior, which appear several weeks after conception. Her nipples will keep becoming bigger, maybe get darker, and discharge semi-clearly. You may sense movement from the puppy and see a larger abdomen as the pregnancy goes on. 


Do human pregnancy tests work for dogs?  

No, is the response.  

Dogs cannot become pregnant with early pregnancy tests (EPTs) for the simple reason that HCG (human choriogonadotropin) levels in urine are the primary indicator of pregnancy in humans. HCG is a hormone that is generated by pregnant people, as the name suggests. 

 Since dogs don't manufacture HCG like humans do, testing for pregnancy in dogs with a human sample would be completely pointless and expensive.  


Stages of Dog Pregnancy 

Dog pregnancies usually last between 58 and 68 days, during which time the development from conception to birth is marked by numerous significant stages. Initially, a female dog lays an egg, and a male dog's sperm fertilizes it to create embryos. This is the process of conception. Embryos insert themselves into the uterine wall approximately 17–20 days after conception. After that, the embryo develops quickly, resulting in the production of structures and organs. Embryos officially become fetuses on day 32 and continue to develop until birth. The mother dog gives birth to her puppies during the whelping stage, which is the last stage. The woman goes through a lot of physical and behavioral changes during these phases as she gets ready to raise and take care of her children. 


Dog Pregnancy Signs Week by Week 

Dogs show many symptoms as their pregnancy progresses that tell us something about them. These symptoms change every week, providing information on how the pregnancy is progressing.  

Slight behavioral changes, tiredness, and increased hunger are possible during the first several weeks. As the pregnancy progresses, more obvious symptoms appear. The expectant woman may start to exhibit nesting behavior in weeks three or four as she looks for a cozy place to get ready for the baby's arrival. 

As the pregnancy goes on, weight increase also becomes noticeable, though each dog's pace of gain varies. Nipple enlargement becomes apparent by weeks five or six as the mammary glands get ready to burst into lactation. The size of the puppies' abdomens grows as they develop inside their mothers.



To sum up, finding out if a dog is pregnant is an important part of getting ready for puppyhood. With prompt and accurate testing, pet owners can guarantee the health and well-being of their pregnant dogs, whether with veterinarian aid or at-home choices. 


How soon can a dog's pregnancy be detected?

Dogs' pregnancies can be detected as early as 22 days after conception using relaxin dog pregnancy tests.

What is the most reliable method to confirm a dog's pregnancy?

Abdominal ultrasound is considered the gold standard for confirming dog pregnancies, providing early detection, and assessing fetal viability and litter size.

Are there any risks associated with using X-rays to confirm dog pregnancies?

Yes, x-rays pose risks to younger fetuses and may be difficult to perform due to the need for restraint.

How can pet owners prepare for a dog's pregnancy?

Pet owners can prepare for a dog's pregnancy by contacting their veterinarian promptly when suspecting pregnancy, considering various testing options, and ensuring proper care for the mother dog.
