So your dog is pregnant and you’re super excited to find out how many little fur babies you’ll be welcoming soon! But wait – can those fancy ultrasound machines actually miss some puppies hiding in there? The answer might surprise you (and explain why you ended up with more puppies than your vet predicted).
As a dog breeder for over 5 years I’ve had my fair share of ultrasound surprises. Trust me, nothing quite compares to expecting 4 puppies and ending up with 7 little bundles of joy! So let’s dive into what you really need to know about pregnancy scans for dogs.
The Short Answer: Yes, Scans Can Miss Puppies!
Let’s not beat around the bush – ultrasound scans can absolutely miss puppies. It happens more often than you might think! The main reasons include:
- Puppies hiding behind each other
- Overlapping heartbeats making counting difficult
- Movement during the scan (those pups can be wiggly!)
- The scan being done too early in pregnancy
- Puppies positioned in hard-to-see areas like up under the ribs
One veterinarian put it perfectly “If you ask any veterinarian if he or she could have missed one or two puppies in the ultrasound, the answer is always yes.”
Understanding Dog Pregnancy Basics
Before we get into the nitty-gritty of ultrasounds, let’s talk about what’s actually happening during your dog’s pregnancy.
Dog pregnancies typically last around 62-64 days (about 9 weeks), though this can vary slightly based on breed and litter size. Smaller breeds tend to have shorter pregnancies and smaller litters, while larger breeds often have more puppies.
The development happens in three main phases:
-
The Ovum Period – Right after fertilization, when the fertilized eggs start growing and eventually implant in the uterine lining
-
The Embryo Period – The embryos grow and develop, with a placenta forming around each one
-
The Fetal Period – Starting around day 35, when organs develop further, bones harden, and puppies start growing rapidly
How Pregnancy is Confirmed in Dogs
There are several ways vets confirm pregnancy in dogs:
1. Abdominal Palpation
This is just a fancy way of saying “feeling the belly.” Around 28-30 days after ovulation, a vet can feel tiny swellings in the uterus. This method is less reliable if your dog is overweight or uncooperative.
2. Relaxin Test
A blood test that detects the hormone relaxin, which is only produced during pregnancy. This can be done around 30 days after breeding.
3. Radiography (X-rays)
X-rays can show puppies once their skeletons start to calcify, usually around days 45-48. This is actually the most accurate method for counting puppies, but it’s done later in pregnancy.
4. Ultrasound
The most common method used between 21-30 days after breeding. Great for confirming pregnancy and checking if puppies are alive, but not so great for accurate counting.
Why Ultrasounds Aren’t Great at Counting Puppies
Here’s the deal – ultrasounds are amazing for confirming pregnancy and checking if puppies are alive and healthy. But they’re notoriously bad at giving you an accurate count of how many puppies to expect.
Let me explain why:
Dynamic vs. Static Images
Ultrasound provides a real-time, moving picture – everything’s constantly moving inside! Unlike X-rays that give you a static image where you can count skulls, ultrasound requires the vet to mentally keep track of which puppies they’ve already counted.
Puppies Playing Hide and Seek
Some puppies might be positioned in a way that makes them invisible during the scan. This is especially true in the early stages of pregnancy when puppies might be hiding under the ribs.
As one source perfectly explains: “In the first stages of pregnancy, your dog’s womb is higher up in her abdomen, under her ribs. This means that any puppies hiding in there might be missed by an ultrasound.”
Heartbeat Confusion
Vets often count heartbeats to determine litter size. But with multiple puppies, heartbeats can overlap and be difficult to distinguish from one another. As one expert puts it: “The main problem has to do with the heartbeats. A specialist will be relying on movement caused by heartbeats when examining the ultrasound.”
Moving Targets
Puppies don’t exactly stay still for their photoshoot! They move around, which means some might be counted twice, while others might not be counted at all.
When is the Best Time for a Pregnancy Ultrasound?
If you want the most accurate results possible from an ultrasound, timing is everything:
- Too early (before 21 days): You might get a false negative because the embryos are too small to see
- 21-25 days: Pregnancy can be confirmed, but counting is very difficult
- 28-30 days: This is considered the sweet spot for ultrasound – you can see heartbeats and better estimate litter size
- After day 30: As puppies grow bigger, they actually become harder to count accurately on ultrasound
Most vets recommend ultrasound around 28-30 days after breeding for the best results.
X-Rays: The Better Option for Counting Puppies
If knowing exactly how many puppies to expect is super important to you (and it should be!), then X-rays are your best bet. But there’s a catch – you’ll need to wait until later in pregnancy.
The ideal time for X-rays is after day 55 of pregnancy. By this point, the puppies’ skeletons are calcified enough to be clearly visible on an X-ray.
X-rays have several advantages for counting puppies:
- They produce a static image where you can count skulls
- Puppies can’t “hide” from an X-ray like they can with ultrasound
- The entire uterus is visible at once
But X-rays have limitations too:
- They can’t tell you if all puppies are alive
- They must be done later in pregnancy
- They expose mom and puppies to a small amount of radiation (though it’s considered safe)
The Singleton Surprise
Here’s something interesting – sometimes ultrasounds show just one puppy (called a singleton), and that can actually be a concern!
A singleton puppy can’t generate enough hormones to trigger labor or even milk production. This often means the puppy grows too large for a normal delivery, and C-sections are commonly needed.
As one source explains: “This can lead to complications after the birth too, such as bottle feeding, if your mumma pup doesn’t have enough milk.”
So if your ultrasound shows just one puppy, make sure your vet is aware so you can prepare for potential complications.
Real Talk: What to Expect from Your Vet
I think it’s super important to have realistic expectations when you take your pregnant dog for an ultrasound. Here’s what you should know:
-
Your vet isn’t being incompetent if they miss puppies – it’s a limitation of the technology
-
The primary purpose of ultrasound is to confirm pregnancy and check if puppies are alive
-
For accurate counting, you’ll need X-rays later in pregnancy
-
Combining different methods (ultrasound + X-rays) gives the best results
And please, be wary of people offering super cheap scans or very early scans – they’re unlikely to be accurate.
My Personal Experience with Scan Surprises
I’ll never forget when my Golden Retriever, Bella, had her first litter. The ultrasound showed 4 puppies, and we were so prepared! We had everything ready for our small litter.
Then came delivery day, and after puppy #4 was born, I thought we were done. But nope! Surprise puppies #5 and #6 made their entrance about an hour later. Talk about a shock!
My vet explained that this is completely normal, especially with larger litters. The puppies were probably stacked behind each other during the scan, making them impossible to see.
Tips for Breeders and Dog Owners
If you’re breeding your dog, here are some practical tips:
- Always prepare for more puppies than shown on the scan
- Consider both ultrasound AND X-rays for the most complete picture
- Wait until day 28-30 for ultrasound for the best results
- Schedule X-rays around day 55 if you need an accurate count
- Keep extra supplies on hand just in case there are surprise puppies
- Monitor labor closely and be ready for more puppies than expected
Final Thoughts
So, can a scan miss puppies? Absolutely! It happens all the time, and it’s not anyone’s fault – it’s just a limitation of the technology.
The best approach is to use ultrasound early to confirm pregnancy and check puppy health, then follow up with X-rays later if you need a more accurate count. And always, always be prepared for surprise additions to the litter!
Remember, whether you end up with 2 puppies or 12, each one is a little miracle that will bring joy to someone’s life. And isn’t that what breeding is all about?

Differences from Other Diagnostic Tools
Dog ultrasound exams offer direct insight into the health and development of embryos, which traditional physical examinations cannot provide. Unlike x-rays that are typically used later in pregnancy to count litter size due to radiation concerns, ultrasound scanning is safe early on and can be performed as soon as 25-35 days gestation.
This allows for earlier detection of pregnancy and assessment of fetal viability without any harmful side effects.
Ultrasound technology stands out by allowing veterinarians to visually monitor the heartbeat of each fetus, a critical marker of viability that other non-invasive tools cannot offer.
Real-time ultrasound also gives an accurate estimation of small litters comprising 1-3 puppies, something that palpation or other methods might miss or inaccurately assess. By providing both structural ultrasound s and functional information (like heart activity), canine ultrasound becomes an invaluable tool in ensuring the health of pregnant dogs and their developing litters far beyond what other diagnostics can achieve.
Understanding the Purpose of a Dog Ultrasound
Abdominal ultrasound in dogs serves as a safe, non-invasive imaging technique that uses high-frequency sound waves to create s of the inside of a dog’s internal organs. Specifically for pregnant dogs, this technology is critical for confirming pregnancy, assessing fetal viability, and determining litter size.
Ultrasounds are most effective between 25-35 days of gestation, offering a glimpse into the womb to monitor the developing puppies. This diagnostic tool stands out due to its ability to provide real-time s, allowing veterinarians to estimate litter sizes accurately—especially in cases of small litters ranging from one to three puppies—and evaluate the health status of each fetus.
Through canine ultrasound scanning services, both breeders and pet owners can obtain essential information regarding fetal heart activity and embryonic development, aiding in the careful attention required during a dog’s pregnancy period.
Detailed ultrasound examinations serve a critical role in canine pregnancy, offering a window into the health and status of unborn puppies. They are essential for confirming a dog’s pregnancy, providing an accurate headcount on future litter size, especially reliable for small litters ranging from 1-3 puppies.
Around 25-35 days gestation is the ideal time for veterinarians to perform ultrasonography, allowing them to assess fetal viability effectively and spot any potential complications early on.
Veterinarians rely on ultrasound technology not just for diagnostic purposes, but also as a tool for continuous monitoring throughout gestation. It ensures both the mother’s and her developing fetuses’ well-being by enabling vets to adjust dietary plans based on real-time observations of weight fluctuations in pregnant dogs.
This high level of prenatal care maximizes the chances of a healthy delivery process while minimizing risks inherent in canine pregnancies.

FAQ
Can puppies be missed on an ultrasound?
Puppies can always be missed on an ultrasound, but it’s especially easy at day 21, when the growing gestational sacs are still hard to distinguish and count. Days 28 and 30 should be perfect for a scan, but don’t leave it too long! The bigger the puppies and your dog’s belly grow, the harder it is to get a clear puppy count!
Can you miss a puppy on a X-ray?
As we’ve discussed, although they have plenty of benefits, ultrasounds are notoriously inaccurate when it comes to counting puppies. No diagnostic tool can be perfect though and it’s possible to miss puppies on x-rays too, if the scan was taken too early for the puppies’ bones to develop.
When do puppies appear on a dog ultrasound scan?
Our experienced team is here to support you every step of the way. Learn when puppies appear on a dog ultrasound scan during canine pregnancy, from early detection at 20 days to detailed development tracking before birth.
Can you see a puppy on an ultrasound?
Ultrasounds are used for estimating litter size but aren’t considered accurate as puppies can be easily missed. When used with other forms of analysis, such as x-rays, they can provide a more accurate guess and they can also provide important information about the health of the puppies. How Far Along The Pregnancy Can You See A Puppy On Ultrasound?
Are ultrasounds wrong on puppy numbers?
I’ve not personally had the experience of breeding dogs, but from what I have read ultrasounds are notoriously incorrect on puppy numbers. Puppies have a habit of hiding up behind the ribs especially in a maiden bitch. Is your vet very experienced with ultrasound?
When should a puppy be scanned?
It’s advisable to wait until at least day 25 or even 28 before getting your pup scanned, as very early pregnancies can be reabsorbed into the mother’s uterus. By leaving more time for the pups to grow, the benefits of a later scan is being able to see the pups in more detail. Why Are Puppies Not Showing On Ultrasound [False Negative]?
Is it possible to miss puppies on an ultrasound?
While it is possible to not see puppies on an ultrasound, the empty sacs are a better indicator of what’s going on. Dogs gestate for about 63 days, and when they’ve reabsorbed the puppies, they do not enter labor at all.
How accurate are puppy scans?
How accurate are dog pregnancy scans? Ultrasound scans are an accurate way of checking that your dog is pregnant and that the puppies are still alive. They can be used to estimate how many puppies there are, but it’s very difficult to do this accurately.
How long do mother dogs miss their puppies?
The mother may initially feel lost without her litter and show signs of depression that could last a few days. Complete separation from their mother and littermates might be scary for a puppy at first, and it’s natural for them to cry or whine during this period of adjustment.
Are dog ultrasounds accurate for puppy count?
Mid-pregnancy ultrasounds provide the most accurate count of puppies expected in the litter.Oct 1, 2024
