Abortion in dogs is a complicated issue that involves various causes. It’s vital to know why it happens and how to take care of the mother and possible babies. Dogs are pregnant for about 57 to 72 days1. During this time, the unborn pups might die, leading to their bodies being absorbed, aborted, or even becoming mummified. Figuring out why an abortion happened is key. Vets do this by checking samples like the baby’s tissues, blood, and the placenta1.
Puppy death shortly after birth is also a big worry1. It’s really important to collect tissue samples the right way. This is because dogs often eat the afterbirth, which makes getting samples tricky1. Keeping these samples in good condition until they can be tested is crucial to get accurate results1.
When many animals get sick at once, taking blood samples from both sick and healthy ones helps vets figure out what’s wrong1. Checking dead puppies requires tools like scalpels and needles1. It’s also important to look for physical problems, such as cleft palates or leg issues1.
Dogs and cats being autopsied must be handled very cleanly to avoid contaminating the tissue samples1. For tests to work right, these samples need to be a certain size1. Looking at the placenta carefully helps to tell the difference between dog and cat pregnancies1.
It’s crucial not to jump to conclusions about what you see in a dead fetus1. Professionals need to carefully decide what these signs might mean.
Key Takeaways:
- The normal gestational period for dogs is 57 to 72 days, and fetal death within this period can result in resorption, abortion, or fetal retention1.
- Neonatal death, occurring within the first 3 weeks after birth, is a significant concern1.
- Proper sample collection, storage, and transport are crucial for accurate diagnostics1.
- In outbreak situations, submitting serum samples from affected and unaffected animals can aid in diagnostic investigations1.
- Detailed external examination and sampling for congenital defects are recommended for neonates1.
- Aseptic collection methods should be followed during necropsies for bacteriology and virology1.
- Placental examination is essential for both dogs and cats, with different characteristics in each species1.
- Proper interpretation of gross findings in the fetus is crucial, as some findings may be incidental1.
Causes of Abortion in Dogs
Abortion in dogs can happen for many reasons related to their reproductive health. These include infections, accidents, birth defects, or problems with drugs. Knowing what causes abortion helps us prevent it in dogs.
Infections like canine herpesvirus are one reason. Anvik’s study in 1991 discussed how this virus affects dogs. It can lead to abortion, so it’s vital to manage this infection2.
Brucella canis, a bacteria, is another cause. To find it, vets need samples like blood and placenta. Early detection and treatment help stop abortion and keep dogs healthy.
Trauma can also cause abortion in dogs. Issues during or after giving birth, such as dystocia or injuries, can end a pregnancy. Helping dogs through labor is key to avoiding these problems.
Birth defects can up the risk of abortion. These might be random or inherited, and toxins can cause some. Spotting and understanding these defects is important for healthy pregnancies.
Some drugs can lead to abortion in dogs too. These include androgens, glucocorticoids, some antibiotics, and painkillers. Vets should be careful with drugs for pregnant dogs to prevent loss.
Working on these issues helps breeders and vets ensure dogs have safe and healthy pregnancies.
Diagnostic Procedures for Abortion in Dogs
When looking into abortion cases in dogs, identifying the cause is key. This involves collecting different samples to test and examine carefully. The normal gestational period for dogs is 57 to 72 days1. It’s critical to collect samples correctly and perform necropsies to diagnose accurately. This helps treat the dog properly.
Sample Collection for Abortion Investigation in Dogs
To figure out why dogs have abortions, stillbirths, or neonatal deaths, collecting the right samples is crucial. We need fetal tissues, and blood from both the fetus and the mother, as well as the placenta. The placenta can tell us more than the fetus itself can1. Labs often give discounts for these tests and may provide kits to help collect these samples1.
It’s important to send the samples quickly, store them well, and transport them right. This avoids tissue decay that can mess up the tests1. In outbreaks, comparing samples from sick and healthy animals in the area helps identify the infection1. Always include full history, like litter size and past health issues, when sending samples1.
Necropsy for Abortion Cases in Dogs
Examining dogs after death is critical to understand why fetal or neonatal deaths happen. This check involves looking the body over, getting samples for tests, and making sure tissues are ready for more detailed study1. Checking the placenta and noting any weirdness is also vital. This can mean taking more samples, making a slide from the membrane, and maybe doing a bacteria test1.
By doing these exams, vets can figure out the reasons for abortion. This leads to right decisions for care and ways to stop future issues.
Management and Treatment Options for Abortion in Dogs
Dealing with abortion in dogs involves different approaches based on the pregnancy stage. Spaying, or ovariohysterectomy, is a common method. It removes the ovaries and uterus, ending and preventing future pregnancies3. Spaying is both safe and effective. It stops unwanted pregnancies and some dog reproductive problems.
Another method is using prostaglandin injections. These involve giving Prostaglandin F2 alpha, a naturally occurring hormone, to induce safe abortion in dogs3. It works by causing the uterus to contract, pushing out the fetus. While generally safe, some dogs might experience mild side effects like panting, trembling, nausea, and diarrhea.
Using dexamethasone is also an option for dog abortion3. This corticosteroid disrupts the hormonal balance needed for the pregnancy, leading to its end. Be mindful of possible side effects including heavy panting, increased thirst, and more frequent urination.
It’s crucial to understand that postcoital douches don’t work in terminating dog pregnancies3. They have no scientific backing and shouldn’t be used as a prevention method. This misconception can lead to unnecessary risks.
Observing your dog after any abortion is vital for early problem detection. Monitoring helps spot issues early on. With the vet’s close supervision, serious health problems can be avoided, ensuring the dog’s health and well-being3.
| Treatment Options | Method |
|---|---|
| Ovariohysterectomy | Removal of ovaries and uterus to terminate and prevent pregnancy |
| Prostaglandin Injections | Administration of prostaglandin to induce safe abortions |
| Dexamethasone | Use of corticosteroid medication to disrupt hormonal balance |
Canine Pregnancy Losses and Neonatal Death
Dogs can lose their pregnancies for many reasons, involving both infectious and noninfectious causes. Knowing why these losses happen is key to keeping dogs healthy when they’re having puppies.
Dogs usually are pregnant for 57 to 72 days. Cats can be pregnant between 52 and 74 days1. When puppies or kittens die within three weeks of being born, it also counts as a pregnancy loss14. It’s important to think about these early deaths when looking at what causes pregnancy losses in dogs.
Figuring out why a puppy or kitten was stillborn or died early involves various tests. These tests include checking the tissues of the fetus, blood from the mother and fetus, and the placenta1. If you have a case like this, you should talk to a vet lab nearby1.
If many animals get sick in places like kennels or cat breeders, checking blood samples from sick and healthy animals can help find the cause1. You should give the lab a full history, including how many puppies were expected, any past problems, vaccination and breeding records, and any new pets1.

To fight against pregnancy losses and neonatal death in dogs, understanding the causes is crucial. Using detailed tests and careful sampling, vets and breeders can find out the reasons. Then, they can work to keep dogs healthy during pregnancy.
Abortion in Cats
Abortion in cats can happen for many reasons. Their pregnancy lasts about 52 to 74 days1. They might lose their pregnancy due to sickness or injury. It’s vital to correctly figure out and handle when a cat’s pregnancy ends early.
Factors Contributing to Feline Abortion
Cats can lose pregnancies for the same reasons dogs do. Illnesses like feline herpesvirus and bowel infections can cause them to miscarry. Injuries from accidents or during birth can also end a pregnancy1. Cat owners need to know these risks and how to avoid them.
Diagnostic Procedures for Feline Abortion
Getting the right diagnosis is key to understanding why a cat may miscarry. Tests include taking samples of fetus tissue, blood, and the placenta. These help find out why the miscarriage happened and check the health of the mother and other kittens1.
Management Options for Feline Abortion
There are different ways to handle cat miscarriages. Vets may suggest medicine or surgery based on the situation. Medicine may involve prostaglandins or hormones. For some cases, a surgery called ovariohysterectomy might be needed1. Owners should talk to their vets about the best option for their cat.
Feline Miscarriage Symptoms
Knowing the signs of a cat miscarriage helps get care quickly. Watch for signs like vaginal discharge, being very tired, not eating, and belly pain. If you think your cat is miscarrying, go to the vet right away1.
Feline Pregnancy Termination Statistics
Knowing why cat abortions happen and how to manage them helps owners take care of their cats. If you see any signs of a miscarriage, getting help from a vet is very important for your cat’s health.

Role of Viral Infections in Abortion and Stillbirth in Dogs and Cats
Viral infections can hurt dogs and cats, leading to abortion and stillbirth. Canine herpesvirus1 is one virus that can cause abortion in dogs. About 69% of breeding kennels in Gauteng Province, South Africa, have this virus2.
Cats also face risks from viral infections. These can cause stillbirths and problems with reproduction. There’s no exact data on cats, but the threat is real.
Viral infections, like canine herpesvirus, spread through direct contact. Infected animals can give it to others, raising the risk of abortion or stillbirth.
Finding out why a dog or cat had an abortion or stillbirth is crucial1. Information about litter size and health status helps understand the virus’s roles. This guides what tests and management are needed next.
In outbreaks, testing serum samples from all animals is helpful1. It shows how the infection spreads and its prevalence.
To diagnose these viral infections1, vets collect blood, placenta, and tissue samples. These are tested to find the virus and any other issues.
Knowing about these viral infections helps vets and breeders prevent them. Vaccines and biosecurity are key to keeping animals safe from these viruses.
Summary of Viral Infections Causing Abortion and Stillbirth in Dogs and Cats
| Viral Infection | Prevalence | Associated Reproductive Issues |
|---|---|---|
| Canine Herpesvirus | 69% (seroprevalence in breeding kennels in Gauteng Province, South Africa)2 | Abortion, stillbirth, reproductive complications |
| Feline Viral Infections | N/A | Stillbirth, reproductive complications |
Understanding viral infections’ impact is key for managing and preventing them. Vets and breeders need to diagnose correctly, collect samples, and take preventive steps. This helps keep dogs and cats’ reproductive health safe.
Traumatic Causes of Abortion in Dogs and Cats
Traumatic causes of abortion in dogs and cats can occur anytime during or after pregnancy. One reason is dystocia, or difficulty giving birth. This can be due to the baby’s position, issues with the mom’s pelvis, or weak labor contractions. Dystocia threatens both the mom and her unborn babies. It can cause lack of oxygen and distress, leading to abortion1.
Another cause of abortion is trauma after giving birth. This can come from accidents or being handled too roughly. Such injuries can harm the mom’s reproductive organs and cause pregnancy loss1.
To lower abortion risks, managing and helping during birth is key. People who breed dogs and cats should watch them closely during delivery. They should get involved right away if there’s trouble. Creating a calm and safe birthing area helps avoid traumatic abortions1.
Breeders and owners must learn about dystocia and other possible problems after birth. If they spot issues like too much bleeding, pain, or strange discharge, they should call the vet quickly. Getting help early can save the mom and her babies1.
Preventing Traumatic Causes of Abortion
“Proper management and assistance during parturition are important in preventing traumatic abortion in dogs and cats.”
Stopping traumatic abortions begins with keeping breeding animals healthy. Regular vet check-ups and exams before breeding can find risks that might lead to abortion. These checks look at the animal’s reproductive health and ability to have healthy babies.
During birth, animals need good care and support. They need a clean, comfy place to give birth, as well as the right food and water. Helping animals during tough births and getting vet advice can prevent many traumatic abortions1.
Educating breeders, owners, and those caring for animals is vital to prevent abortions. It’s important to recognize signs of distress and know when to get vet help. Ensuring careful handling and promoting responsible breeding can lower the chances of abortion1.
In short, traumatic abortions can happen during or after giving birth, often because of dystocia. To prevent this, monitoring and early care are needed, as well as vet support. Teaching breeders and owners about responsible practices can also help reduce these sad events1.
Congenital Defects and Abortion in Dogs and Cats
Congenital defects in dogs and cats can lead to abortion. It’s key to understand and spot these issues early to avoid breeding problems. These defects might pop up randomly, stem from genetic issues, or happen due to toxin exposure.
These defects happen during fetal development. They can affect numerous body systems, like the heart, lungs, bones, and brain.
Genetic disorders causing abortion are passed down and can mess up how embryos grow. This might cause miscarriages or stillbirths. Breeders and vets need to keep an eye out for these disorders to make smart breeding choices and care for pets properly.
Toxins are another danger for congenital defects and abortion in pets. If pets are exposed to certain chemicals, medicines, or environmental hazards while pregnant, it can hurt the babies and lead to complications.
Sometimes, congenital defects just happen without a clear reason. These might be due to chance mutations or errors when the embryo is growing.
Doctors use different tests to figure out and manage congenital defects. These help understand the defect better and decide how to help.
For the best diagnosis, sending in fetuses/neonates that didn’t make it, their placenta, and the mom’s blood is ideal1.
For testing, vets collect samples like fetal tissue and the mom’s blood. These are important for further analysis, like looking at diseases or genetic issues.
Looking at the placenta helps figure out why congenital defects and abortions happen1. Dog and cat placentas have unique features that can help in these investigations.
When checking how far along a dead fetus or baby was, details like weight and tooth development are clues1. These help figure out the development stage and what might have gone wrong.
Evaluating what we see in a necropsy is vital to tell apart issues that caused death from those that didn’t1. Correctly reading these signs aids in a proper diagnosis and treatment.
It’s crucial for those breeding pets to know about congenital defects and what causes them. By knowing the risks and taking steps to prevent them, breeders and vets can help reduce the chances of abortion and encourage healthy breeding.
Drug-Related Causes of Abortion in Dogs and Cats
Some drugs can impact pregnancy in dogs and cats. Breeders and veterinarians need to know these drugs and their risks. These risks affect the health of the animals. Androgens, corticosteroids, antimicrobials, and more4 can cause problems. It’s key to be careful with these drugs in pregnant animals.
Androgens
Androgens like testosterone can change animal features. They help treat some health issues in pets. But, they might harm developing babies and lead to pregnancy loss4.
Corticosteroids
Corticosteroids are used for their healing effects. Yet, they can up the abortion risk in pets4. Deciding to use them in pregnant animals takes careful thought.
Antimicrobials
Antimicrobials fight infections in pets. But, they can also risk pregnancy4. Using them in pregnant pets should be done with caution.
Other Medications
Other drugs can also affect pregnant pets. This includes some painkillers, NSAIDs, and tranquilizers4. Always talk to a vet before giving these to pregnant animals.
Some drugs raise the abortion risk in pets. Breeders and vets must understand these effects well. With careful choices, the harm from drugs can be lessened. This helps keep pets healthy during pregnancy.
Importance of Breeder Education and Research
Breeder education in reproductive health and continuous research are key to reducing pregnancy losses in dogs and cats. Knowledgeable breeders make smart choices and take steps to keep their animals healthy.
Studying pregnancy losses in dogs and cats helps us understand why these losses happen. This research lets breeders use proven methods to increase their programs’ success.
“Responsible dog breeders spend time learning about their breed, canine health, and training.”5
Good breeders always seek to learn more and understand their breed better. They dive into breed standards and learn what makes an ideal dog. By going to dog shows and studying pedigrees, they gather important info.
Knowing about genetics and health tests is crucial for breeding the right way. Breeders should learn about their breed’s specific genetic issues. This knowledge helps them choose the best mates, reducing genetic problems in puppies.
“The American Kennel Club offers resources and webinars for breeders to plan and prepare for litters.”5
The AKC provides great resources and education for breeders. They offer webinars, seminars, and guides on breeding responsibly. These help breeders get ready for litters, keeping mothers and puppies safe.
Breeders should plan and finalize stud contracts early. Planning ahead ensures a good match for quality, temperament, and health. Good matches lead to successful pregnancies and healthy puppies.
“It is advised to breed bitches by the time they are 2 to 3 years old to avoid age and CEH-associated infertility issues.”6
Timing is everything in breeding. It’s best to breed female dogs when they’re between two and three years old. This reduces fertility issues and problems from CEH. Breeding at the right age increases the chance of healthy babies.
| Factors | Recommendations |
|---|---|
| Bitch Health | Bitches should be in good health, up to date on vaccinations, and free of underlying diseases for improved fertility. (Statistical Data:6) |
| Nutrition | Maintaining a healthy weight, feeding a balanced diet approved by the Association of American Feed Control Officials (AAFCO), and timing vaccinations no later than three weeks before the cycle are recommended for bitches. (Statistical Data:6) |
| Genetic Testing | Breeders should proactively identify potential genetic disorders in their breed and perform appropriate health testing to make informed breeding decisions. (Statistical Data:5) |
| Mating Pair Selection | The selection of a mate should consider genetic compatibility rather than relying solely on physical appearance. (Statistical Data:5) |
Along with breeding, staying current on reproductive health research is vital. Working with vets, going to conferences, and reading reputable journals helps. This way, breeders help move knowledge forward.
“Breeders should understand the basics of genetics to make informed decisions about mating pairs.”5
“The importance of knowing genetic disorders and inheritance patterns in dog breeding is highlighted.”5
Understanding genetics is key for breeders. It helps them choose the right dogs to mate. Knowing about genetic problems and how they’re passed on helps avoid harmful traits in puppies.
Education and research are pillars in dog and cat reproductive health. By learning and using good practices, breeders improve breeds and animal welfare.
