Can A Dog Miscarry One Puppy?


Miscarriage is defined as the spontaneous loss or death of one or more unborn puppies during pregnancy. It can happen at any stage of gestation and involve just one puppy or an entire litter. A miscarriage of a single puppy, while less common than losing a whole litter, does occur in dogs. This is sometimes referred to as singleton loss.

Miscarrying one puppy can be emotionally painful for dog owners who were looking forward to a new addition. While the death of even one puppy is sad, it’s important to know that a singleton loss does not necessarily mean the mother dog cannot go on to have healthy litters in the future. With proper care and monitoring, many dogs can recover fully from losing a single puppy.

This article will cover the causes, signs, diagnosis, and treatment for a dog miscarrying one puppy. It will also provide guidance on caring for the mother dog afterwards and look at the impacts on future pregnancies. Understanding the implications and how to respond can help dog owners provide the best possible care if their dog experiences the loss of a single puppy.

Causes of Miscarrying One Puppy

There are several potential causes that can lead to a dog miscarrying just one puppy in a litter. Some of the most common include:

Issues with the individual puppy: Sometimes there may be developmental issues with a specific puppy that prevents it from surviving. This could include genetic defects, abnormalities, or other problems that arise as the embryo develops in the womb. These issues mean the puppy is not viable.

Health problems in the mother dog: Various illnesses and conditions in the mother dog can lead to miscarriage of one or more puppies (Purina). These include infections like brucellosis, herpesvirus, or toxoplasmosis. Metabolic diseases like diabetes or kidney issues may also increase miscarriage risk. Hormonal imbalances, such as low progesterone levels, can sometimes cause miscarriage of a single puppy as well.

Trauma: Injury, stress, or other trauma sustained by the mother dog may sometimes lead to the loss of a single puppy. Trauma can include falls, blows to the abdomen, strenuous exercise, etc. This type of trauma may rupture blood vessels supplying one of the puppies, leading to its death.

Signs of Miscarrying One Puppy

There are several signs that a dog may be miscarrying one puppy in a litter. Some of the most common signs include:

Vaginal Discharge – A dog that miscarries one puppy may have abnormal vaginal discharge such as blood or pus. The discharge may be brown, green, black, or colored and appear at any time during pregnancy. This discharge indicates the loss of a fetus.

Abdominal Pain – A dog who miscarries one puppy may experience abdominal pain or discomfort. This occurs as the uterus contracts to expel the deceased fetus. The dog may seem restless, pace, vocalize, or pay attention to that area of her body.

Lethargy – After miscarrying a single puppy, a dog may become lethargic or depressed. She may refuse to eat or drink normally. The emotional impact and physical exertion of the miscarriage causes fatigue and loss of appetite. Her energy levels may decline.

These signs of a single puppy miscarriage require prompt veterinary attention to monitor the dog’s health and ensure no fetal material remains in the uterus. Treating any discharge or infection and supporting the dog emotionally are important steps.

Diagnosing a Single Puppy Miscarriage

Diagnosing a single puppy miscarriage in dogs typically involves a veterinary exam, ultrasound, and bloodwork.

During the exam, the vet will feel the dog’s abdomen and look for any discharge or other physical signs indicating a possible miscarriage. They may also use a stethoscope to listen for puppy heartbeats.

Ultrasound is one of the most definitive ways to diagnose a single puppy loss. The vet can use ultrasound imaging to visually confirm the number of viable fetuses vs. resorbed ones in the uterus.[1]

Bloodwork can also provide clues. A dog’s progesterone levels will drop rapidly after miscarriage. Checking progesterone along with other hormone levels can help confirm if a miscarriage occurred.[2]

While an at-home miscarriage is possible, having a veterinary exam is highly recommended for an accurate diagnosis of a single puppy loss.

Treating a Dog After Miscarrying One Puppy

The treatment for a dog after miscarrying one puppy focuses on providing supportive care and addressing any underlying health issues. According to VCA Animal Hospitals, the main components of treatment are:

Rest – It’s important to restrict your dog’s activity after a miscarriage and allow her time to recover both physically and emotionally. Take short, gentle walks and limit strenuous activity.

Antibiotics – If there is an infection present, such as from retained fetal parts, the vet may prescribe antibiotics to treat it. Common antibiotics used are amoxicillin or cephalexin.

Address Underlying Issues – The vet will run tests to determine if there are any hormonal imbalances, uterine infections, or other health problems that led to the miscarriage. These issues can then be treated to prevent future miscarriages.

In most cases, miscarriage is traumatic for the dog, so be patient and provide extra love and care while she recovers. Monitor for any concerning symptoms and follow up with your vet within a few weeks to ensure proper healing.

Emotional Impact on the Dog

A dog that miscarries one of her puppies may experience sadness and anxiety as she searches for her missing puppy. She may seem restless or depressed in the initial days following the miscarriage. However, most dogs are resilient and bounce back quickly from the loss of a single puppy.

After giving birth, mother dogs form strong bonds with their litters. So when a pregnancy ends unexpectedly, the mother dog will likely still have strong maternal instincts and may search the area looking for her missing puppy. She may seem confused about the change in her body after carrying puppies for so long.

As the hormones from pregnancy decrease and the dog realizes the puppy is gone, she usually adjusts and returns to her normal self. Especially if it is her first litter, she is unlikely to understand exactly what happened. But dogs live in the moment and will be comforted by the presence of any surviving puppies.

With lots of love and affection from her owners, the dog should return to her typical happy, energetic self before long. Just provide some extra attention and patience as she processes the loss. As long as she has her people by her side, she will be ok.

Impact on Future Litters

Dogs who miscarry one puppy can usually go on to have healthy litters in the future. However, the impact on future pregnancies depends on the cause of the single puppy loss.

If the miscarriage was due to an infection, illness, or other medical condition, getting prompt treatment can help prevent it from happening again. Once the underlying cause is addressed, most dogs are able to carry their next litter to full term.

If the miscarriage was caused by a genetic or anatomical issue, the outlook may be more uncertain. Certain conditions like uterine abnormalities can make it difficult for a dog to successfully carry a pregnancy. Your veterinarian can perform exams and testing to determine if there are any ongoing issues that need to be managed.

In many cases, miscarrying one puppy does not necessarily mean future litters will be affected. But identifying the cause through veterinary care maximizes the chances of a healthy next pregnancy. With proper medical care and observation, most dogs can go on to deliver healthy litters after losing a single puppy.

Caring for the Dog After a Single Puppy Loss

After losing one puppy in a litter, it is important to focus on caring for the mother dog both physically and emotionally. The mother dog will likely need time to rest and recuperate from the traumatic experience. It’s recommended to keep her in a quiet area away from loud noises or other dogs that could cause her stress.

Monitor the mother dog closely in the days following the single puppy miscarriage and contact your veterinarian if you notice any concerning discharge, lethargy, loss of appetite, or other symptoms. Your vet can examine her to ensure there are no retained placental tissues or infection setting in.

Be patient and allow the mother dog to grieve the loss of her puppy. Offer her gentle affection and don’t force her to resume normal activities until she is ready. Make sure she has fresh water and nutritious food to help her regain strength.

Give the mother dog space if she seems withdrawn following her loss but also provide plenty of loving comfort when she seeks it. Speak gently, pet her, and reassure her during this difficult time. With time and support, she can recover both physically and emotionally from this tragedy.

When to Be Concerned

While losing one puppy from a litter is unfortunate, it’s generally not a cause for major concern. According to VCA Animal Hospitals, miscarriages can occur due to placental insufficiency, congenital defects, or unknown causes in otherwise healthy dogs.[1]

However, if your dog begins miscarrying or reabsorbing puppies frequently, it could signal an underlying health issue. Some problems that may lead to recurrent miscarriages include:[2]

  • Hormonal imbalances
  • Chronic illnesses like kidney disease
  • Infections of the uterus
  • Genetic defects

If your dog miscarries multiple litters, be sure to take her to the vet for a full exam. Getting to the root cause of the problem is important for her health and future breeding potential. With treatment of any underlying conditions, dogs can go on to have healthy litters after a single or recurrent miscarriage.

Preventing Single Puppy Miscarriage

There are a few things dog owners can do to help prevent single puppy miscarriages:

Provide good prenatal care. Make sure the pregnant dog is getting proper nutrition, exercise, and veterinary care. A high-quality diet rich in nutrients helps support a healthy pregnancy. Regular vet checkups allow monitoring for potential issues.

Treat any health issues. Illnesses like infections or hormone imbalances can sometimes lead to single puppy loss. Treating conditions that could compromise the pregnancy as soon as possible boosts the chances for a full litter. According to VCA Animal Hospitals, infections are typically treated with IV fluids and injectable antibiotics which may prevent miscarriage.

Follow proper breeding practices. Allowing the female to fully mature before breeding, proper timing of breeding, preventing trauma or stress, and limiting breeding frequency can help avoid complications like single puppy miscarriage. Responsible practices promote healthy litters. As Purina notes, miscarriages are uncommon in healthy dog pregnancies.
