How Long is an American Bully Pregnant?

You’re probably wondering, an American Bully is pregnant for approximately 63 days, give or take a few. This breed, like all dogs, has a gestation period that spans over about two months. However, variances can occur, and it’s not unusual for delivery to happen a few days earlier or later.

You should monitor your dog’s temperature regularly as a drop often indicates the onset of labor within 24 hours. Providing a quiet and comfortable environment is also crucial during this time.

How Do You Know If Your American Bully Is Pregnant?

To confirm if your American Bully is pregnant, you can try several methods. A vet can perform palpation, ultrasound, or a Relaxin Hormone Test. If these don’t work or are inconclusive, an X-ray might be your next best bet.


Palpation also known as palpitation is one of the simplest methods to know if the American bully is pregnant or not although it is not very accurate.

It just involves touching and gently pressing the belly of the American bully to feel the presence of the puppies.

Palpation can be used to detect pregnancy only after it has been 28 to 30 days from the date of mating.

While it is a simple method, it is always recommended not to do it yourself; instead, consult a vet

Here’s a quick guide:

Early stage (around 4 weeks)

  • Small, grape-sized bumps can be felt
  • These are the developing embryos

Later stage (around 5-6 weeks)

  • The bumps will have grown larger, similar to golf balls
  • These are the growing puppies


In just a few weeks, you’ll be able to confirm your American Bully’s pregnancy with an ultrasound, which will show any number of growing puppies.

This technology uses high-frequency sound waves that create images of your dog’s womb. Around days 25 to 35, the vet can discern small, fluid-filled sacs, each one a potential puppy.

Don’t worry, it’s a painless procedure for your pet. The ultrasound also provides valuable information about the puppies’ health and development. You’ll get to know how many pups to expect, but remember, it’s not always 100% accurate. It’s a wonderful tool, but it’s not infallible.

Relaxin Hormone Test

You can also check if your American Bully is pregnant by running a Relaxin Hormone Test, which becomes more reliable after 30 days of gestation.

It involves blood testing of your bully to check the level of the relaxin hormone.

Relaxin is a hormone produced by the placenta and its detection indicates a high probability of pregnancy.

Here’s what you should know about it:


  • Not as accurate in early pregnancy
  • Increases in accuracy after 30 days


  • Blood sample required
  • Results available in a few days

It’s important to note that while this test is a good indicator, it’s not 100% foolproof. Always consult with your vet for confirmation. Understanding this test’s reliability and procedure can help you better manage your Bully’s pregnancy.

X-ray (radiography)

You’ll need at least 45 days into your American Bully’s pregnancy to see any definitive results on an X-ray. This imaging tool allows your vet to confirm a pregnancy and estimate the number of pups. It’s a safe procedure that won’t harm the mother or her unborn puppies.

However, it’s not a perfect science. Small or less-developed puppies might not show up on an X-ray. It’s also not the best method for identifying potential health issues. But, it’s a useful tool for getting a rough idea of what to expect.

What is False Pregnancy in an American Bully?

False pregnancy in your American bully, also known as pseudopregnancy, is a condition where she’ll show signs of being pregnant when she’s not. It’s a hormonal imbalance that triggers the body to mimic gestation. Understanding the signs can prevent unnecessary concern.

Here’s what you might notice:

Physical changes:

  • Enlarged abdomen
  • Swollen mammary glands

Behavioral changes:

  • Nesting behavior
  • Restlessness

Just remember, these signs don’t always mean she’s pregnant. Consult with your vet if you’re unsure. They might perform a physical exam or ultrasound to confirm.

False pregnancy can be stressful for your bully, but it’s usually harmless and resolves on its own. If symptoms persist, your vet may recommend treatment to balance her hormones.

At What Age Can an American Bully Get Pregnant?

An American bully can get pregnant at a young age, typically around six months, but it’s recommended to wait until they’re physically mature. Breeding too early can lead to complications. They should ideally be at least two years old before becoming pregnant to ensure they’re fully developed.

Breeding your American bully responsibly entails conducting health tests, verifying genetic compatibility, and ensuring she’s emotionally ready. You’ll notice signs of readiness during her heat cycle which occurs every six months. Look for swelling and discharge.

It’s a delicate process, so make sure you’re well-informed and prepared. Remember, your bully’s health and well-being should be your top priority. Always consult a vet to make sure she’s fit for pregnancy.

American Bully Pregnancy Sign – You Need to Look For

You might notice your American Bully experiencing appetite changes, one of the first indicators of pregnancy.

Their behavior might shift too, becoming more affectionate or defensive, as physical changes to their body become apparent.

Watch for nesting behaviors and increased urination frequency as well, these signs are usually evident in the later stages of pregnancy.

Appetite Changes

During your American Bully’s pregnancy, you’ll likely notice fluctuations in her appetite. This is a common sign and part of the normal process. Initially, she may lose her appetite due to morning sickness but as the pregnancy progresses, her appetite will increase significantly. This is to nourish both her and the growing puppies. It’s key to monitor this carefully to ensure she’s getting proper nutrition.

Understanding appetite changes:

Early pregnancy:

  • Loss of appetite can occur due to hormonal changes.
  • Morning sickness might occur, similar to humans.

Mid to late pregnancy:

  • There’s usually a significant increase in appetite.
  • This is due to the energy needs of growing puppies.

Always consult with your vet if you’re unsure or notice anything unusual.

Behavioral Shifts

Two major behavioral shifts you’ll probably notice are increased affection towards you and nesting behaviors, both signaling your Bully’s pregnancy progress. These changes are natural and indicative of your Bully’s preparation for motherhood. Increased affection, such as more cuddling and following you around, indicates her need for more comfort and security. Nesting behaviors, like scratching at her bed or finding secluded spots, are her attempts to create a safe space for her upcoming pups.

Affection LevelsNormalIncreased
Nesting BehaviorsAbsentPresent
Energy LevelsHighLowered
Physical ChangesNoneNoticeable

Understanding these shifts can help you provide the care your Bully needs during this crucial time. Remember, your Bully’s well-being is paramount for a healthy litter.

Physical Body Changes

Somebody might notice their Bully’s belly starting to round out, which is one of the physical changes that occur during pregnancy. You’ll also see their nipples enlarge and darken. It’s important to understand these signs, as they indicate your Bully is transitioning from one stage of pregnancy to another.

Here are a few more physical changes you should keep an eye out for:

Weight gain:

  • This is inevitable as your Bully is carrying puppies. Keep track of the weight gain to ensure it’s healthy and not excessive.

Coat changes:

  • Their coat may become shinier due to hormonal changes, but some might also experience fur thinning.

Nesting Behaviors

You’ll notice that a few weeks before delivery, your Bully will start showing nesting behaviors, which usually involves finding a quiet, safe place to give birth. This is a natural instinct, aimed at ensuring a secure environment for her puppies.

You might find her digging in secluded areas, or rearranging her bedding more frequently. It’s essential to provide a comfortable whelping box for this purpose. It should be large enough for your Bully to stretch out, but small enough to keep the puppies close to their mother. Line it with soft, washable bedding and keep it in a warm, quiet location.

Observing these behaviors is crucial for understanding your Bully’s pregnancy stages. By catering to her nesting needs, you’re paving the way for a successful delivery.

Increased Urination Frequency

In the weeks leading up to delivery, you’re likely to notice an increase in your Bully’s urination frequency, which is another common sign of pregnancy. This is due to the growing puppies pressing on her bladder. You shouldn’t be alarmed, as this is a normal part of the pregnancy process.

To help manage your Bully’s increased urination:

  • Make sure she has constant access to a clean place to urinate. This could be:
  • A well-maintained outdoor area
  • Puppy pads if she’s an indoor dog
  • Monitor her for signs of discomfort or urinary tract infections, such as:
  • Blood in urine
  • Excessive licking of the urinary area

Vomiting or Nausea

During the early stages of your Bully’s pregnancy, it’s not uncommon for her to experience vomiting or nausea. This is similar to the morning sickness seen in human pregnancies. It’s caused by hormonal changes as her body prepares to support the growing pups.

This might worry you, but don’t panic. It’s a natural part of the process and usually subsides after the first few weeks. However, it’s essential to keep an eye on her. If the vomiting is severe or persists beyond a few weeks, it’s time to consult your vet. Prolonged vomiting can lead to dehydration and weight loss, which isn’t good for her or her pups.

Darkening of Nipples

It’s quite normal to notice a darkening of your Bully’s nipples as a sign of pregnancy. This is a result of hormonal changes preparing your dog’s body for nursing. Along with this change, you might also see an increase in nipple size.

To better understand these changes, consider the following aspects:

Hormonal Changes-

  • Progesterone: This hormone stimulates the mammary glands, causing nipple darkening.
  • Prolactin: Released later in the pregnancy, it further prepares the mammary glands for milk production.

Physical Changes-

  • Nipple enlargement: Usually accompanies darkening, a prep for nursing.
  • Swelling: Mild swelling can be observed around the mammary area.

Increased Affection Seeking

You’re likely to see an increase in your Bully’s affection-seeking behavior as another sign of pregnancy. This emotional change is triggered by hormonal fluctuations, primarily the surge in progesterone and estrogen.

Your Bully might become more clingy, demand more attention, or seek constant physical contact. She could also become more protective. This is entirely normal, as she’s instinctively preparing for the arrival of her pups.

However, it’s crucial not to confuse this with signs of distress or illness. If she’s uncomfortable, excessively whining, or showing signs of pain, it’s time to contact your vet.

In short, an increase in affection is a common pregnancy symptom, but always stay alert to any unusual behaviors.

Tips to Take Care of Pregnant American Bully

To ensure your pregnant American Bully’s health, you’ll need to adjust her diet according to the vet’s advice. This is crucial as her nutritional needs change during pregnancy. Here are some general suggestions:

  • Chicken, beef, and fish are excellent protein sources.
  • Add Omega-3-rich fish oil for healthy fats.

Enhance her meals with puppy food:

  • Puppy food has the nutrients needed for growing pups.
  • Gradually mix in with her regular food.

Remember, these changes should be gradual and always under a vet’s supervision.

Monitoring her health throughout her pregnancy is fundamental, as is ensuring plenty of rest and mild exercise. By doing so, you’re paving the way for a safe delivery and healthy puppies.

When your American Bully is ready to give birth, she can do so naturally or through a C-section, depending on her health and the number of puppies.

During labor, the mother may exhibit signs of discomfort, such as restlessness, panting, and nesting behaviors.

As the contractions become stronger, the puppies are pushed out one by one. It’s important to provide a calm and safe environment for the mother during this time.

Have a vet’s number on speed dial in case of complications.


C-section or caesarean section is a surgical procedure done by vets during the delivery of the pup.

In this procedure, the vet gives anaesthesia to the dog and creates a cut into the uterus to pull the pup out of it.

This procedure is used only if it is not safe for the dog to deliver the pup naturally, or may be used when it is necessary to deliver the pup right away due to some complications.

Here’s a simple table to help you weigh your decision:
