Puppy Roundworms in Poop: Symptoms, Treatment, and Prevention

Puppy roundworms in poop can be a concerning and unpleasant discovery. What are puppy roundworms in poop? They are small, parasitic worms that usually live inside the intestines of mammals, including dogs and cats. Puppies can get roundworms from their mother through birth or during early life stages.

Roundworm larvae eat host cells and can mature into adult worms 6 to 30 days after infection. Infected puppies may show signs of illness, such as loose stools, fever, vomiting, diarrhea, abdominal pain, and an increased appetite. 

Treatment for a puppy roundworm infestation typically includes treating the puppies with anti-parasitic medication and providing nutritional support during the treatment process. 

In some cases, surgery may also be necessary to remove eggs from the intestinal tract. Knowing what to look for in inspiration of your pup’s stool is essential if you suspect they might have an infection – watch for brownish fecal material containing small worm eggs.

Puppy roundworms in poop can be a cause for concern. 

These tiny parasites can live in any feces and are typical in puppies. When your puppy ingests these worms, they will likely develop diarrhea, vomiting, lethargy, poor appetite, weight loss, and fever – all signs of infection.

They are small creatures that typically measure 1 to 2 inches long. They have three pairs of legs and feed on organic matter like grasses or weeds. 

Although Roundworm infections aren’t generally life-threatening for most dogs and cats, they can still lead to serious health problems if left untreated. 

If you notice any unusual symptoms in your pet – such as frequent diarrhea or vomiting – bring them to see their veterinarian for diagnosis and treatment options as soon as possible.

They are transported in the feces of infected animals, meaning they can be found in any area where a dog or puppy lives and plays. 

Roundworm eggs can survive up to two weeks outside the body, so preventing them from entering your home on contaminated surfaces is important. If you believe your puppy may have roundworms, visit his veterinarian as soon as possible for a diagnosis and treatment plan. Here are signs that your puppy may have:


It is one of the most common symptoms of roundworms, and it usually indicates that large numbers of worms are active in the intestine.


Puppies who vomit frequently may also have diarrhea because their digestive systems become overloaded with fluid and waste products.

Abdominal swelling: 

Roundworm larvae often accumulate in the abdominal region (i.e., between the ribs) due to their preference for moist environments. This swelling is not always visible but can lead to pain when touched or an inability to move around freely.

Poor growth: 

Puppies with roundworms often grow slower than usual, and their coats may be dull or thin.

Dull coat: 

Roundworm-infested puppies may also develop a poor coat of hair that is easily tangled.


Many symptoms of roundworm infection overlap with those seen in severe cases of pneumonia, making it difficult for owners to determine which condition is causing their pet’s lethargy and inability to stay warm.


Roundworms can also cause dogs to cough up blood or mucus. In most cases, however, these symptoms only indicate that your puppy has roundworms—not necessarily sickly or facing serious health risks.

However, if your dog displays one or more of these seven signs of roundworm infection, fever, or diarrhea, it is best to bring them to the vet for a check-up.

Puppy roundworms are typical parasites in dogs and puppies. The infections can induce severe intestinal problems, including vomiting, diarrhea, anorexia (loss of appetite), and dehydration. Treatment is required to prevent serious health complications caused by roundworm infection.

There are some methods to treat a puppy roundworm infestation, but the most useful method depends on the stage of worm development. In the early stages, your veterinarian may prescribe antibiotics or castor oil injections to kill the worms quickly. 

If additional treatment is necessary after initial rounds of medication have been administered or if there is evidence that eggs are still present in the dog’s system, your veterinarian may opt for oral medications like praziquantel (Prozact) or ivermectin (Amethopterin). 

Oral medications

Oral medications work best when given at regular intervals throughout therapy; however, they cannot be used if pregnant females are intended for breeding because their offspring could also be infected with roundworms.


Prevention is always better than cure — keep your puppy clean by regularly cleaning its litter box and being well-groomed. You can also help protect other pets in your home from roundworm infection by properly supervising any new dog additions and washing hands thoroughly before handling any pet.

Diagnosing Roundworms in Puppies 

Roundworm infections most commonly occur when puppies eat their mother’s worm-filled feces. 

If your puppy has roundworms, it will likely have diarrhea and may refuse to eat or drink. Your veterinarian will perform a fecal exam to determine the degree of infection and prescribe treatment if necessary. 

No vaccine is available to prevent roundworm infection in puppies, but treating them as soon as possible helps prevent serious health complications. If you suspect your pet has roundworms, take them to see a veterinarian as soon as possible for an examination and appropriate treatment recommendations.

They are typical parasites found in both animals and humans. They tend to infect puppies through their feces but can also be contracted from contact with contaminated soil or water. Infected puppies may exhibit diarrhea, lethargy, anorexia (loss of appetite), vomiting, and fever.

Prevention is your best medicine when it comes to roundworm infestations; the following simple tips will help keep your puppy healthy:

  • Keep your puppy’s living area clean and free of feces – This includes not allowing them to play outside where they might be potty on the ground or walk into other dogs’ yards who have been playing nearby. Also, ensure that any toys you give your pup are kept kennel-free so they cannot kick them around and contaminate them with their waste.
  • Always pick up after your puppy – If you can’t take him outdoors for excretion (due to weather conditions etc.), at least try to scoop his poop before throwing it away or putting it in the trashcan – Doing this will reduce the chances of roundworms being spread around by fecal matter contamination 
  • Wash your hands thoroughly after taking your puppy or cleaning up after them – So thorough hand washing afterward is essential for preventing infection 
  • Follow Your Veterinarian’s Deworming Recommendations – Puppies should be dewormed before arriving at

The Best Medication for Puppy Roundworms: Keeping Your Pup Healthy

The most commonly used medications for treating puppy roundworms in poop are:


Anthelmintic work by paralyzing the roundworms and preventing them from reproducing, which allows the puppy’s immune system to eliminate the parasites from their body.

Several types of anthelmintics are available for treating roundworm infections in puppies, including fenbendazole, pyrantel pamoate, and milbemycin oxime. Each medication works slightly differently, so it’s important to consult a veterinarian to determine which medication is best for your puppy’s needs.


It works by interfering with the roundworms’ ability to absorb nutrients, which eventually leads to their death. Fenbendazole is typically administered orally for several days and effectively eliminates roundworms.

Pyrantel pamoate

Pyrantel pamoate is another common medication used to treat roundworm infections in puppies. It paralyzes the roundworms, allowing the puppy’s body to pass the parasites naturally. Pyrantel pamoate is typically administered orally as a single dose, eliminating roundworms.

Milbemycin oxime

Milbemycin oxime is a third medication used to treat puppy roundworms in poop. It prevents the roundworms from reproducing, eventually leading to their death. Milbemycin oxime is typically administered orally monthly as a preventative measure against roundworms and other parasites.

In addition to medication, there are several steps to prevent infections in puppies. These include practicing hygiene by washing your hands regularly and keeping your puppy’s living area clean and feces-free. It’s also important to regularly deworm your puppy, especially if they spend time outdoors or come into contact with other animals.

Treating and preventing roundworm infections in puppies is important to keep your pup healthy. By working with a veterinarian to choose the best medication for your puppy’s needs and taking steps to prevent future infections, you can help ensure your puppy grows strong and healthy.

If you notice any signs of illness or injury in your puppy following treatment with this medication, please consult a veterinarian immediately.

You also want to avoid contact with soil as much as possible because roundworm eggs can survive for up to two months on surfaces inside homes (although they typically die within 48 hours when exposed outdoors).

Risks and complications of roundworm infections in puppies

Roundworm infections in puppies can have several potential risks and complications. These parasites can cause a range of symptoms, from mild to severe, and can even be life-threatening in some cases.

Digestive problems

One of the primary risks of infections in puppies is that they can cause digestive problems. Puppy roundworms in poop can include vomiting, diarrhea, and poor appetite. If left untreated, these digestive issues can lead to dehydration and malnutrition, which are particularly dangerous for young puppies.

Respiratory problems

They can also cause respiratory problems in puppies. When the roundworm larvae migrate through the lungs, they can induce coughing and difficulty breathing. In severe cases, this can lead to pneumonia, which can be life-threatening for young or immunocompromised puppies.

Zoonotic transmission

Another potential complication of roundworm infections in puppies is the risk of zoonotic transmission. Roundworms can be transmitted from puppies to humans, particularly children, through contact with infected feces. This can lead to various human symptoms, including abdominal pain, diarrhea, and fever.

Intestinal blockages or neurological problems

Rarely roundworm infections can cause more severe complications, such as intestinal blockages or neurological problems. It’s important to seek veterinary care if you suspect your puppy may have a roundworm infection, as prompt treatment can help prevent these more serious complications.

Roundworm infections in puppies can have several potential risks and complications, ranging from mild digestive issues to more severe respiratory problems and even zoonotic transmission. By preventing roundworm infections and seeking prompt veterinary care if you suspect your puppy may be infected, you can help keep them healthy and reduce their risk of developing these complications.
