Easy ways to find out if your dog is pregnant at home and at the vet
Download Article
Your dog’s been acting different lately, and you know she spent the last few weekends with her male dog friend. Could she be pregnant? No matter what first made you suspect that your dog is pregnant, you need answers. Luckily for you, we have all the information you’re looking for right here, from clinical testing and symptoms of heat. With a bit of knowledge and a vet visit, you can determine if your dog is pregnant or not.
This article is based on an interview with our dog breeder, Kateryna Zabashta, owner of Emma’s Frenchies. Check out the full interview here.
Things You Should Know
- One of the best ways to determine pregnancy is to check a dog’s nipples. If they’re swollen and have a rosy hue, they’re probably pregnant.
- In the early stages of pregnancy, a dog can be lethargic, overly affectionate, and have a change in appetite.
- Veterinarians can perform invasive tests like abdominal palpation and ultrasounds to detect pregnancy, but they may not be as effective as a relaxin hormone test.
Steps
-
Enlarged nipples: One of the most reliable signs of pregnancy is if a female dog “pinks up” or has swollen or enlarged nipples. A pregnant dog’s nipples will become larger and rosier during the first month of pregnancy. [1] X Expert Source Kateryna Zabashta
Dog Breeder Expert Interview. 19 March 2021.- Dogs don’t produce milk until the end of gestation or when the puppies are born; however, the nipples may leak a clear or milky discharge throughout the pregnancy.
-
Lethargy and behavioral changes: Monitor your dog’s activity levels to see if she’s pregnant. Some dogs may be sleepier during pregnancy, especially in the first month. They may be more affectionate and cuddly and want to play less. Your dog isn’t being lazy—she’s saving her energy to grow her puppies! [2] X Expert Source Kateryna Zabashta
Dog Breeder Expert Interview. 19 March 2021.- For instance, if she’s napping more often and falling behind on her walks, it may be because she’s pregnant.

Changes in appetite: A pregnant dog will go through many changes, but how much food she eats may be the most obvious. In the early stages of pregnancy, your dog may eat less and experience morning sickness. [3] X Expert Source Jeannie McElroy
Canine Enthusiast & Breeder of Champion European Boxers Expert Interview. 20 May 2022. By the second month, she may start eating a lot and get a bigger appetite than usual—she has more mouths to feed, after all. [4] X Expert Source Kateryna Zabashta
Dog Breeder Expert Interview. 19 March 2021.- If your dog is constantly throwing up and eating and drinking very little, it may be a good idea to see a vet to ensure that her and her puppies are healthy.
-
Weight gain: If your dog is pregnant, she’ll most likely gain weight around her waist and midsection. Her expanding center is a positive sign, as healthy pregnant dogs gain 20 to 50% of their weight during pregnancy. Typically, you’ll be able to see a distended tummy when she’s 45 to 50 days pregnant.

-
Nesting behavior: Your dog may start moving blankets around and creating a “nest” to sleep in. She might start scratching at the floor or moving all her toys to a new place. While this behavior isn’t something you’ll notice right away, it could be a later sign that she’s preparing for her litter to come.

- Help your dog prepare by building her a nesting box. A cardboard box, cozy blankets, and pillows can make your pregnant dog feel comfortable and ready for what’s to come.

Ask your vet to perform an abdominal palpation on your dog. A vet can look for initial signs of pregnancy by massaging your dog’s abdomen. Not only is this the cheapest way to examine your dog, but it’s also less invasive. Basically, the vet will feel your dog’s stomach for the puppies. This test is the most successful between day 21 and 31 of gestation. [7] X Research source
- The best time for abdominal palpation is day 28 because the puppies are now big enough to make a bump in the womb.
- By day 35, each puppy is surrounded by their own fluid, making it harder for a vet to accurately predict the number and size of the puppies.
- Keep in mind that an abdominal palpation isn’t always conclusive. Depending on your dog’s anatomy and the puppies positioning, a vet may suggest another testing option.
-
Bring your dog to the vet for a blood test. A hormone test is the most accurate way to detect canine pregnancy. A vet will take a sample of your dog’s blood and test it for the pregnancy hormone relaxin. When a dog is pregnant, relaxin releases from the placental tissue. This singular pregnancy hormone can be detected by the 30th day in a dog’s pregnancy. [8] X Trustworthy Source American Kennel Club The American Kennel Club (AKC) is a purebred dog pedigree registry in the United States.

-
Schedule an ultrasound for your expecting dog. Ultrasound scans are the most popular and best way to detect pregnancy early on. Vets recommend scheduling your dog for an ultrasound around the 28th day of gestation. [9] X Expert Source Jeannie McElroy
Canine Enthusiast & Breeder of Champion European Boxers Expert Interview. 20 May 2022. This way, they can determine the number of puppies, predict the gestational age, and detect heartbeats. [10] X Research source- Ultrasounds aren’t an invasive test, but if your dog has lots of fur, it may need to be clipped or shaven for the device to work.
-
Ask your vet if an X-ray will help diagnose your dog. While X-rays are not typically the first recommendation for detecting pregnancy in a dog, they can be effective during the later stages of pregnancy. These radio-active scans are an excellent way to determine the number of puppies in the litter and spot any abnormalities in the mother or puppies’s development. X-rays give the best results after day 50 of gestation, but a vet may recommend one sooner if there’s a medical complication. [11] X Research source
- Sedation may be necessary when X-raying a dog, which can drop a pregnant dog’s blood pressure and put her and her puppies at risk.
- Radiography isn’t typically recommended unless a specific diagnosis is needed.

Check to see if your dog is spayed or not. If you’ve had her since she was a puppy, you’ll know whether or not she’s had her uterus and fallopian tubes removed. However, if the dog came to you as an adult from a rescue center, you might not know. Take your dog to the vet just to be sure, as they can do a quick examination to see if pregnancy is possible.
- An unspayed dog comes into heat twice a year, so if you’ve owned her for over 9 months and she hasn’t been in heat, she’s probably been spayed.
- Heat is the clinical term for a female dog’s reproduction cycle. Spaying a dog is eliminates the ability to have a litter and breeding instincts. [12] X Research source
- There are 4 stages in a dog’s reproductive cycle: proestrus, estrus, diestrus, and anestrus. A female dog is most likely to get pregnant in the estrus stage, which can last 3 to 4 days or 7 to 11 days. [13] X Research source
- While the duration of heat depends on the individual dog, it’s usually about 18 days and starts between 6 and 24 months of age. [14] X Trustworthy Source American Society for the Prevention of Cruelty to Animals Leading organization dedicated to the prevention of animal cruelty Go to source
-
Look for vaginal abnormalities, like vaginal discharge. When your dog is in heat, their vaginal area will look different. An enlarged, swollen vulva (the outer part of the vagina) often starts just before heat starts. Bloody discharge occurs the first 7 to 10 days and may become a lighter color in the middle of the cycle. [15] X Expert Source Kateryna Zabashta
Dog Breeder Expert Interview. 19 March 2021.- Place a white sheet or towel on your dog's bed to see if she’s in heat. This way, you can catch the vaginal discharge before your dog cleans herself.
- Dogs are most likely to get pregnant when their discharge is a lighter color, as this is a sign of ovulation.
-
Notice if your dog is abnormally calm or aggressive. Dogs in heat experience hormonal imbalances. Because of this, they may act differently. How your dog behaves depends on her usual demeanor and personality: if she’s usually placid, she may become short-tempered; if she’s home-loving, she may start wandering. [16] X Research source
- Aside from a slight behavioral change, your dog should be in good health.
- If your dog lacks energy, loses her appetite, vomits, or drinks heavily, contact a vet for advice, as this may be a sign of an underlying womb condition like pyometra.

-
Recall when your dog was around a male dog. Female dogs can’t get pregnant on their own; they need some help from the male department. Think about the last time your dog was around other dogs, and then recall if any were male. Your dog could’ve mated with another dog at the dog park, during a playdate, or around the neighborhood.
-
Find out if the male dog is neutered. Neutered or castrated male dogs can mate with female dogs, but they can’t impregnate her. Check-in with the suspected dog’s owner to see if they’ve been neutered. If they have, another dog may be the father; if not, they may be responsible for your dog’s future puppies.
- If a dog has been castrated 4 weeks before mating, there’s a very small chance that some of his sperm was left behind after the procedure, and he could impregnate another dog.
-
Keep a record of the date your dog mated. Having a rough estimate of when your dog mated with another dog can help you track the potential pregnancy. For instance, if she mated with a dog 3 months ago, he’s most likely not the father; however, a dog she was with 3 weeks ago may be the father. [17] X Research source
- A dog's average gestation or length of pregnancy is around 63 days.
-
Talk to a vet about your findings to determine if your dog is pregnant. If you suspect your dog may be pregnant, bring her to the vet. Relay what you know about your dog’s heat cycle and when you suspect she mated. Based on the hormonal stage of her heat, a vet can predict the gestation of the pregnancy. [18] X Research source
- From the first day of diestrus (the 3rd stage of heat), gestation is 56 to 58 days.
- From the initial rise in progesterone, 64 to 66 days.
- Keep in mind that if the dog mated but is still in heat, it’s too early to know if she’s pregnant.
-
Familiarize yourself with the conditions that mimic pregnancy. Believe it or not, some conditions can make a dog appear and act like she’s pregnant when she’s not, such as false pregnancies and pyometra. Pseudopregnancy or false pregnancy is often caused by a hormonal imbalance after heat and resolves itself on its own. [19] X Research source Pyometra, on the other hand, is a bacterial infection that causes the womb to fill with pus and can be life-threatening. [20] X Research source
- Pyometra can cause an enlarged stomach, extreme third, loss of appetite, blood poisoning, organ failure, and if left untreated, death.
- Always bring your dog to the vet if you suspect they’re pregnant, as a vet can provide life-saving treatments if necessary.
- Ultrasounds are the most effective way to detect false pregnancies and pyometra. [21]

QuestionWhat can cause a 14 month old puppy who is not pregnant to have swollen nipples?Dr. Elliott, BVMS, MRCVS is a veterinarian with over 30 years of experience in veterinary surgery and companion animal practice. She graduated from the University of Glasgow in 1987 with a degree in veterinary medicine and surgery. She has worked at the same animal clinic in her hometown for over 20 years.She might be having a phantom pregnancy. This is a hormonal event that happens to some female dogs, where their body incorrectly believes them to be pregnant. The body then undergoes changes associated with pregnancy, such as enlarged mammary glands and even milk production.

QuestionMy rescue dog is neutered but is leaking milk. What should I do?Dr. Elliott, BVMS, MRCVS is a veterinarian with over 30 years of experience in veterinary surgery and companion animal practice. She graduated from the University of Glasgow in 1987 with a degree in veterinary medicine and surgery. She has worked at the same animal clinic in her hometown for over 20 years.If a female dog is neutered while she's having a false pregnancy, this can mean that she will produce milk permanently. The vet can either give a hormone injection, which will dry up the milk for 4-6 months (when another dose will need to be given), or there is a liquid medicine, which helps to dry up milk. Also, try not to let the dog mother cuddle toys, as this reinforces the milk production.

QuestionMy dog was mounted by another dog while she was in heat, but she is no longer bleeding. Is it still possible for her to get pregnant?Dr. Elliott, BVMS, MRCVS is a veterinarian with over 30 years of experience in veterinary surgery and companion animal practice. She graduated from the University of Glasgow in 1987 with a degree in veterinary medicine and surgery. She has worked at the same animal clinic in her hometown for over 20 years.Typically, a female dog ovulates sometime around day 9-14 of her estrus cycle. This is also when the bloody discharge appears to dry up, but then it returns for the final third of the heat. If it was during this middle part of the season when she mated, then pregnancy is likely. If, however, it was when she was coming to the end of her season (day 21 plus), then ovulation is less likely but not impossible, so the risk of pregnancy decreases.

Before you try to detect pregnancy in your female dog, figure out whether she has been spayed, has been in heat recently, or has been in contact with an unaltered male dog. If your dog has not been in heat or around a male dog in the last 2 months, she is probably not pregnant. However, if she has, look for signs of pregnancy, like her nipples becoming elongated and her belly growing. If you suspect your dog is pregnant, take her to the vet 28-30 days after the date you think she was impregnated to be sure. To learn how to tell if your dog is in heat, see our Veterinary's tips below!
