Confirming Canine Pregnancy: How to Test If Your Dog Is Expecting Puppies

If your pooch is paired up with a suitor, you may wonder if puppies are on the way. While some signs of pregnancy in dogs are obvious, early confirmation requires testing. There are various options for detecting if your dog is expecting based on physical and behavioral changes, veterinary exams, ultrasounds, x-rays, and blood tests. Let’s explore the timeline of canine pregnancy, signs of possible pregnancy, available dog pregnancy testing methods, and how to care for mom through gestation.

Canine Gestation Timeline and Early Signs

  • Breeding occurs – The optimal fertility window is days 10-14 of the heat cycle.
  • Implantation – Embryos implant into the uterus around days 15-21 post-breeding.
  • Physical changes – Enlarged nipples, weight gain, and appetite changes occur around weeks 3-4.
  • Morning sickness – Possible vomiting and lethargy in early pregnancy around weeks 3-4.
  • Belly swelling – Abdomen expands as puppies grow around week 4-5.
  • Behavior changes – Decreased activity, and nesting instinct emerges around week 5-6.
  • Fetal movement – Detectable baby movements felt inside the belly around weeks 6-8.

These early signs indicate pregnancy is likely but not guaranteed. Dog Pregnancy Testing is needed to confirm.

Dog Pregnancy Testing Options

Here are methods for accurately diagnosing canine pregnancy:

  • Veterinary Palpation – The vet manually feels the abdomen for fetal swelling from day 20-25 onwards. An enlarged uterus confirms pregnancy.
  • Ultrasound – An abdominal ultrasound detects fetal presence, heartbeats, and health from around day 20-25 after breeding.
  • X-ray – Radiographs visualize puppy skeletal structures late in pregnancy, after 45 days from breeding.
  • Blood Tests – Relaxin hormone levels can confirm pregnancy as early as day 21-25 with over 95% accuracy.
  • Witness Fetal Movement – Seeing or feeling pups move in the belly after 6-8 weeks post-breeding indicates pregnancy.

For the most definitive early answer, blood tests combined with ultrasound scans provide accurate confirmation of dog pregnancy tests and health.

Important Puppy Preparation Tips

Once dog pregnancy testing is confirmed, here are key ways to care for your expecting pooch:

  • Feed puppy food or more calories – Pregnant and nursing dogs need 2-3 times more nutrition.
  • Supplement vitamins – Prenatal vitamins support healthy puppy development.
  • Limit strenuous exercise – Take gentle walks but avoid strain.
  • Create a whelping box – A cozy, quiet space for birthing puppies.
  • Puppy-proof your home – Relocate toxic chemicals, cover electric cords, and remove clutter.
  • Research signs of labor – Monitor for nesting behavior, body temperature drops, and behavioral changes.
  • Frequently vet check-ups – Monitor mom and puppies’ progress and health until birth.

FAQs About Dog Pregnancy Testing 

1. How soon can pregnancy be detected in dogs?

Answer: Pregnancy in dogs can be detected through various methods. Blood tests, available from 3-4 weeks along, offer an early indication. Ultrasounds confirm pregnancy at around 4-5 weeks, while physical changes in the form of enlarged nipples, weight gain, and other signs typically emerge around 6 weeks.

2. What household items can test dog pregnancy?

Answer: It’s essential to rely on professional veterinary testing for accurate results. No home items or DIY options can reliably confirm pregnancy in dogs. Veterinary tests, such as blood tests and ultrasounds, are necessary for accuracy and proper evaluation.

3. Do canine pregnancy tests indicate litter size?

Answer: While ultrasounds and x-rays can provide estimates of the number of puppies, they are not perfect indicators. On average, a litter size for dogs can range from 5-10 pups. These estimates can be obtained through professional veterinary examinations.

4. Can dogs show pregnancy signs without being pregnant?

Answer: Yes, false pregnancies, known as Pseudopregnancy, can occur in dogs. Hormonal fluctuations may lead to signs such as enlarged nipples, weight gain, and nesting behaviors even when the dog is not carrying puppies. Professional veterinary assessment is crucial to distinguish between true and false pregnancies.

5. Does pregnancy change dog behavior?

Answer: Pregnancy in dogs can indeed lead to behavioral changes. Hormonal shifts during pregnancy can cause lethargy, moodiness, increased affection, reduced activity, and the emergence of protective nesting instincts. Observing these changes can be an indicator of the dog’s pregnancy status.


If puppies may be on the way after your dog is bred, early accurate dog pregnancy testing helps provide vital preparation time. Blood tests combined with veterinary ultrasounds offer the most definitive confirmation of canine pregnancy. With your vet guiding prenatal care and birth planning, you can keep the expectant pooch and future puppies as healthy and happy as possible.
