Why Deworming a Pregnant Dog is Important
Worms are common in dogs. Many dogs carry worms without showing clear signs. But pregnancy changes things. Worms can cause big problems for pregnant dogs and their babies. Getting rid of worms is a key part of good care for a mother-to-be dog.
Grasping the Threat: How Worms Harm Mom and Puppies
Worms are more than just gross. They steal food from the dog. This means the mother dog might not get enough nutrients. She needs these nutrients to stay strong and grow healthy puppies.
More importantly, worms can easily pass from the mother dog to her puppies. This is called worm transmission to puppies. It can happen in two main ways:
- Before birth: Some worm larvae (baby worms) can travel across the placenta into the unborn puppies while they are still inside the mother. This is a major way roundworms in pregnant dogs spread.
- Through milk: Worm larvae can also get into the mother’s milk. Puppies can get worms just by nursing. This is common for both roundworms and hookworms pregnant dog puppies.
Worms are very dangerous for young puppies. Puppies have tiny bodies. Worms can cause big health issues in them.
Deciphering the Risks of Not Deworming
Ignoring the need to deworm your pregnant dog carries significant risks of not deworming pregnant dog:
- Poor Health for the Mother: Worms can make the pregnant dog weak. They can cause weight loss, poor coat, and low energy. This is bad when she needs all her strength for pregnancy and birth.
- Puppies Born with Worms: As mentioned, puppies can be born with worms already inside them.
- Sick Puppies: Worms cause many problems in puppies. They can have poor growth, pot-belly look, vomiting, diarrhea, and anemia (low red blood). Hookworms pregnant dog puppies are especially known for causing severe anemia, which can be deadly quickly in young puppies.
- Death of Puppies: Sadly, heavy worm loads can be fatal for puppies. They can die from sickness or lack of food.
- Problems with Milk: Worms can affect the mother’s ability to make enough milk.
- Spread to Humans: Some dog worms can pass to humans, especially children. This is a public health concern.
Because of these dangers, veterinarians strongly recommend deworming pregnant dogs as part of standard care.
Timing is Key: When to Deworm Your Pregnant Dog
The best time to start thinking about deworming is actually before your dog gets pregnant.
Preparing for Pregnancy: Deworming Before Breeding
Ideally, you should talk to your vet about deworming pregnant dog before breeding. Your vet will likely suggest a complete deworming to clear out any existing worms. This gives the mother a clean start before she gets pregnant. It helps lower the number of worms that could cause problems later. A fecal test (checking poop for worm eggs) might be done to see what worms are present.
Deworming During Pregnancy: A Specific Plan
Deworming during pregnancy needs a careful plan. Not all dewormers are safe for pregnant dogs. Your vet will create a specific deworming schedule pregnant dog. This plan is based on the type of dewormer used and the dog’s needs.
A common approach involves deworming late in the pregnancy. The goal is to kill worm larvae that become active during the last part of pregnancy. These are the larvae that can cross into the puppies. A typical deworming schedule pregnant dog might involve giving medicine daily from about day 40 of pregnancy until about two days after she gives birth. However, the exact timing and medicine depend totally on your vet’s advice.
Your vet might also suggest deworming again after the puppies are born, often at the same time the puppies are dewormed. This helps control worms that can pass through milk.
Finding Safe Dewormers for Pregnant Dogs
Not every worm medicine is okay for a dog that is expecting puppies. Some dewormers can hurt the unborn babies. This is why you must never just grab a dewormer off a store shelf and give it to your pregnant dog. You need to use safe dewormers for pregnant dogs prescribed by your vet.
Approved Dewormers
Veterinarians know which deworming drugs are safe to use during pregnancy. Common safe options include:
- Fenbendazole: This is often the dewormer of choice for pregnant dogs. It is considered safe and effective against common worms like roundworms, hookworms, whipworms, and some types of tapeworms. It’s often given daily for several days late in pregnancy.
- Pyrantel Pamoate: This dewormer is also generally considered safe for pregnant and nursing dogs. It works well on roundworms and hookworms. It’s often used for initial deworming of young puppies too.
- Selamectin/Moxidectin: Some topical parasite preventives (applied to the skin) that contain these ingredients are considered safe and can help control certain internal worms as well as external parasites. Your vet will advise if these are right.
It is crucial to emphasize again: Only use the specific product and dosage recommended by your vet. Do not use over-the-counter products unless your vet tells you exactly which one.
Dewormers to Avoid
Some dewormers can be harmful to pregnant dogs or their puppies. These might include:
- Certain broad-spectrum dewormers not tested or approved for use in pregnancy.
- Dewormers meant for other animals.
- Dewormers that contain ingredients known to cause problems in pregnancy.
This is why you must always consult veterinarian pregnant dog deworming. They have the knowledge to pick the right medicine.
The Deworming Process: What to Expect
Giving your dog deworming medicine is usually simple.
- Form: Dewormers come in different forms: pills, liquids, or granules to mix with food. Your vet will choose the best type for your dog.
- How to Give: You will need to give the medicine as instructed by your vet. This might be a single dose or daily doses for several days.
- After Giving: Most dogs have no reaction. Sometimes, a dog might have mild signs.
Possible Side Effects of Deworming
Most of the time, side effects deworming pregnant dog are minor or do not happen at all when using safe, vet-approved medications at the correct dose.
Possible mild side effects could include:
- Mild tummy upset
- Vomiting
- Diarrhea
- Loss of appetite
These signs are often temporary. They usually pass within a day or two. The risks from worms are much higher than the risk of these mild side effects from the right medicine.
When to Call Your Vet
If you see any worrying signs after giving the dewormer, call your vet right away. These might include:
- Severe or constant vomiting
- Severe or bloody diarrhea
- Weakness or collapse
- Shaking or muscle tremors
- Any behavior that seems very unusual for your dog
While rare with approved medications, it’s always best to check with your vet if you are concerned.
Preventing Worms: A Broader Look
Deworming is a treatment, but preventing worms is also important. Good worm prevention pregnant dog practices help reduce the chance of a worm problem in the first place.
Cleanliness is Key
Worms often spread through poop. Cleaning up your dog’s poop right away is one of the best ways to stop worms from spreading.
- Pick up poop every time your dog goes outside.
- Dispose of poop safely.
- Keep the dog’s living area clean. This means cleaning bedding and kennels often.
Controlling Pests
Some worms use other animals, like fleas, as a way to get into dogs. Tapeworms, for example, can be spread by fleas. Controlling fleas is part of worm prevention. Talk to your vet about safe flea control for pregnant dogs.
Eating rodents or other small animals can also expose dogs to worms. Try to prevent your pregnant dog from hunting and eating these animals.
Regular Fecal Checks
Even with prevention, dogs can still pick up worms. Having your vet check a sample of your dog’s poop regularly (called a fecal exam) can find worms early. This allows treatment before a big problem starts. Your vet might do a fecal check as part of the pre-breeding health check and again during pregnancy.
Safe Environment
Keep your pregnant dog away from areas where many dogs gather and where hygiene might not be great, like crowded dog parks if poop isn’t picked up well.
The Essential Role of Your Veterinarian
We cannot stress this enough: You must consult veterinarian pregnant dog deworming. They are the experts. They will:
- Confirm your dog is pregnant.
- Check your dog’s overall health.
- Discuss your dog’s history with worms and previous deworming.
- May perform a fecal test to see what worms are present.
- Choose the safest and most effective dewormer for your specific dog and her stage of pregnancy.
- Create the correct deworming schedule pregnant dog.
- Tell you the right dose of medicine.
- Explain how to give the medicine.
- Advise you on what side effects to watch for.
- Guide you on worm prevention methods.

Trying to guess or use products meant for non-pregnant dogs can be very dangerous. Always follow your vet’s advice precisely.
Example Deworming Schedule (For Illustration Only)
This is just an example. Your vet will give you the real plan for your dog.
| Time Period | Action | Why? |
|---|---|---|
| Before Breeding | Fecal test and broad-spectrum deworming if needed. | Clear existing worms for a healthy start. |
| Early to Mid-Pregnancy | Routine care, potentially a fecal test. No deworming unless vet advises. | Most deworming is avoided early unless necessary. |
| Late Pregnancy (approx. day 40 – birth) | Daily or specific schedule of vet-approved dewormer (often fenbendazole). | Kill larvae activated by pregnancy to prevent transmission to puppies. |
| After Birth (with puppies) | Vet may recommend deworming mom again when puppies are dewormed. | Control worms passed through milk and from the environment. |
REMEMBER: This is NOT a substitute for vet instructions. Get your dog’s specific plan from your vet.
Life After Deworming & Birth
Even if the mother is dewormed, the puppies will still need to be dewormed starting at a young age (usually around 2 weeks old). This is because some worm larvae can survive even with the mother’s deworming, and puppies are very vulnerable. Your vet will give you a deworming schedule for the puppies too.
Fathoming the Importance of a Clean Start
Giving puppies the best start means protecting them from worms. Deworming the pregnant mother is a critical step in this process. It lowers the number of worms the puppies are exposed to in the womb and through milk. This makes the puppies healthier and stronger from day one.
Frequently Asked Questions (FAQ)
Q: Can over-the-counter dewormers be used for pregnant dogs?
A: No, generally not. You should only use dewormers specifically prescribed by your veterinarian for pregnant dogs. Many over-the-counter products are not safe during pregnancy and could harm the puppies.
Q: What types of worms are most common in pregnant dogs and puppies?
A: Roundworms and hookworms are the most common worms that spread from mother dogs to their puppies.
Q: If I deworm my pregnant dog, will her puppies be born completely worm-free?
A: Deworming the mother greatly reduces the chance of severe worm problems in puppies.
