Luckily for you, we’ve laid out everything you need to know in this article, including what to look for and veterinary tests. Knowing if your dog is pregnant is a breeze with our help, so read on to learn about the leading signs.

Things You Should Know

  • A pregnant dog will start to gain weight around her stomach and waist before her pregnancy starts to show.
  • A tell-tale sign that your dog might be pregnant is if her nipples “pink up” and become rosier and more pronounced.
  • If your dog’s pregnant, she may start eating more, get tired easily, or crave more or less attention than usual.
  • Always take your dog to the vet if you suspect pregnancy, as they can do an ultrasound or run a blood test to confirm or deny pregnancy.

    A pregnant dog’s nipples will be rosier in color (more so than usual) and grow in size, so they’re more prominent. [1] This usually indicates that the dog is about 2 to 3 weeks pregnant.

    Pregnant dogs tend to gain weight around their stomach and waist during the 2nd or 3rd week of pregnancy. This is completely normal—your dog is making more room for her puppies! [2]

    Believe it or not, most dogs don’t “show” their pregnancy until the third half of pregnancy, which is 6 to 9 weeks since conception. If your dog’s stomach is more pronounced than usual, she’s most likely pregnant (especially if her nipples and mammary glands are swollen and plump). [3]
    • Try gently placing your hand on your dog’s belly. As the dog’s pregnancy progresses, there’s a greater chance you’ll be able to feel the puppies inside.
    • The mammary glands produce the milk the puppies will drink, which causes a pregnant dog’s nipples to swell.

    As her tummy grows, expect her to want to eat bigger meals and snack more throughout the day. After all, she has more mouths to feed! [4]
    • Talk to your veterinarian about how to care for your pregnant dog and when to increase her food rations, as additional calories could benefit her and the growing pups.
    • Know that your dog will likely have a reduced appetite 12 to 24 hours before whelping or giving birth. [5]

    A pregnant dog may be drowsier or more lethargic than normal, especially as her belly grows. This is most noticeable if your dog is naturally full of energy. [6] Take note if your dog would rather take an abnormal nap than play fetch like usual.
    • This isn’t necessarily a sure sign of pregnancy, as many other underlying illnesses and conditions could cause changes in behavior. Always bring your dog to the vet, just to be sure.

    How a dog emotionally reacts to her pregnancy all depends on her personality. Some dogs become more affectionate and attention-seeking, while others shy away from pets and cuddles. [7] So, notice if your dog suddenly wants to be pet all the time or hides in a room away from people and other animals.
    • This change doesn’t automatically mean your dog is pregnant, but it could be a good indicator if she’s showing other pregnancy symptoms.

    [8] Your dog may gather blankets, shred paper, or bunch together bedding or clothing to make a warm nest for her puppies. This behavior isn’t always observed, but if your dog does this out of the blue, she’s most likely about to whelp (give birth). [9]
    • Help your dog nest by providing her with a cardboard whelping box and plenty of extra blankets or towels.
    • Talk to your veterinarian about helping your dog give birth and specify any health or behavioral concerns to get the most personalized care.

    This physical examination is painless, and only requires the veterinarian to feel the outside of your dog’s belly with their forefingers. This helps them examine the womb and feel the outline of the potential puppies. [10]
    • Palpation works best when the dog is between 3 and 4 weeks pregnant, as the embryonic vesicles can be easily felt. [11]
    • If the veterinarian feels anything, they’ll move on to an ultrasound or X-ray test to ensure they’re feeling fetuses rather than feces.

    [12] With this test, they’re looking for the hormone relaxin , which is generally present during the 4th week of pregnancy. If relaxin is present, your dog is definitely pregnant.
    • A relaxin hormone test is often used to decipher pseudo pregnancies from real pregnancies, as a dog won't produce the hormone unless she’s actually pregnant.

    With this, they can listen for heartbeats and count how many puppies there are (just like a human ultrasound). This is a sure way to confirm pregnancy in your dog, as long as she’s 2 or more weeks pregnant. [13]
    • Heartbeats are usually heard within 3 weeks of pregnancy.
    • Counting the number of puppies or fetuses can sometimes be difficult, as they often like to hide behind their siblings.
    • The vet may need to shave your dog’s belly fur if she’s extra fluffy.
    • Some dogs may need to be sedated for an ultrasound, especially those that get anxious at the vet’s.

    [14] With ultrasounds being the main test for dog pregnancies these days, an X-ray is only used in cases where the exact number of puppies needs to be known or there are suspected complications.
    • If you have a smaller dog, the veterinarian may take an X-ray to calculate the size of the puppies to determine whether a natural birth or c-section is the safest option.

    Some breeders like to get X-rays so they can check for and count the number of puppies. Not all breeders do this, though.

    An ultrasound scan can detect pups from around 21 days, while a blood test from 28 days can confirm pregnancy. Often the earliest physical sign of pregnancy is 'pinking up,' when the dog's nipples become swollen, pink, and more noticeable.

      Warnings

      • False pregnancy or pseudopregnancy is a common occurrence in dogs. A few weeks after going into heat, a dog can exhibit signs of pregnancy, such as enlarged nipples and increased appetite, without actually being pregnant. Always bring your dog to the vet if you suspect pregnancy.
        Thanks

      About This Article

      Article Summary X

      If you’re wondering if your dog is pregnant, check along her belly to see if her nipples are pink, which is one of the earliest signs of pregnancy. About 21 days after the dog has mated, her gums will appear white for 2-3 days if she is pregnant. The dog’s belly won’t show that she’s pregnant until the final weeks, at which time it will become rounded and the mammary glands will begin to develop, so if you need to know sooner, take the dog to the vet for a blood test or ultrasound. If you want to know about your dog's behavioral changes from our Veterinarian co-author, keep reading!
