Home Remedies for Dog Worms: What Works and What's Risky
By Dr. Zubair Khalid, DVM, MS, PhD ·
Most home remedies for dog worms do not kill the parasites, and some can poison your dog. The worms that infect dogs need specific prescription dewormers, and heartworm disease requires prevention because no home treatment can cure it. This article is educational and is not a substitute for veterinary diagnosis or treatment.
Quick Answer
- Intestinal worms (roundworms, hookworms, whipworms, tapeworms) are treated with prescription dewormers, not kitchen ingredients.
- Heartworm disease cannot be treated at home. It requires veterinary care and, in many cases, a series of injections.
- Some popular home remedies, including certain human medicines and essential oils, are toxic to dogs [1][2].
- Dogs can pass some worms to people, so prompt treatment protects your whole household [3][4].
- If you see worms in your dog's stool or vomit, call your vet for a fecal test and the right medication.
What Dog Worms Are, In Plain Words
"Worms" is a catch-all word for intestinal parasites that live inside your dog's gut. The common ones in the United States are roundworms, hookworms, whipworms, and tapeworms. Each has a different body shape, life cycle, and treatment.
Heartworms are different. They live in the heart and lungs, not the gut, and they are spread by mosquitoes. A dog with heartworms may look normal for months before coughing, tiring easily, or struggling to breathe.
Because these parasites are so different, one home remedy cannot cover them all. A dewormer that kills tapeworms may do nothing for whipworms. That is why veterinarians identify the worm first, then choose the drug.
Signs Owners Notice
Some dogs with worms have no signs at all. Others show problems that range from mild to serious.
- Worms in stool or vomit (roundworms look like spaghetti, tapeworm segments look like grains of rice)
- A potbelly, especially in puppies
- Weight loss despite a normal appetite
- Dull coat, poor growth, or low energy
- Diarrhea, sometimes with blood or mucus
- Scooting or licking the rear end
- Coughing or exercise intolerance (possible heartworm)
A study of dogs in Portugal found parasites in 22.4% of fecal samples, and the most common were whipworms, roundworms, and hookworms [5]. Another study in India found intestinal parasites in 35% of dogs tested, with hookworms detected most often [4]. Dogs with very soft or soft stools had higher positivity rates than dogs with normal stool [4].
If your dog has diarrhea, do not assume worms are the cause. Many conditions look alike. You can read about other common digestive issues in our guide to Dog Constipation Home Remedies That Actually Work, but a fecal test is the only way to know for sure.
Causes and Risk Factors
Dogs pick up worms in several ways. Puppies can get roundworms from their mother before birth or through nursing. Dogs get hookworms and roundworms from contaminated soil, and they get tapeworms by eating fleas or raw meat.
Risk goes up with certain lifestyles and settings.
- Puppies and dogs in shelters or breeding kennels
- Dogs that visit dog parks, hunt, or eat things off the ground
- Dogs with fleas (fleas carry tapeworm larvae)
- Dogs living in areas with mosquitoes (heartworm risk)
- Dogs that are not on monthly prevention
Dogs can act as reservoirs for parasites that also infect people [3]. Hookworms and roundworms are zoonotic, meaning they can pass from dogs to humans [6][4]. Children and people with weakened immune systems are at higher risk. That is one more reason to treat worms quickly and to pick up stool promptly.
How Worms Are Diagnosed
Your veterinarian will ask about your dog's history, then collect a fresh stool sample. The sample is examined under a microscope using a flotation method that concentrates parasite eggs [4]. Different flotation solutions can give different results, so a negative test does not always mean your dog is worm-free.
For heartworm, your vet uses a blood test. This is usually done yearly as part of prevention monitoring.
Sometimes the diagnosis is obvious. If you bring in a worm you found in your dog's stool or vomit, your vet can often identify it by sight. Tapeworm segments, for example, are distinctive.
Home Remedies for Dog Worms: What Works and What's Risky
This is the part most owners search for, so let's be direct. There is no reliable home remedy for dog worms that replaces a prescription dewormer.
What Does Not Work
Many folk remedies circulate online. Common ones include garlic, diatomaceous earth, pumpkin seeds, apple cider vinegar, and coconut oil. None of these are proven to clear a worm infection, and garlic can be toxic to dogs in larger amounts. Do not rely on them to treat a dog that has worms.
What Is Actually Risky
Some home remedies are worse than useless. Human medications are a frequent problem. Pet Poison Helpline notes that even common human drugs like Pepcid AC should only be given after contacting your vet, because what helps a person can harm a dog [1][2]. The same caution applies to any human dewormer. Dog doses are calculated by weight and species, and the wrong drug or dose can cause serious harm.
Essential oils, including tea tree and eucalyptus, are also dangerous for dogs. Never apply them to your dog or add them to food.
If you think your dog ate something toxic, call Pet Poison Helpline at (855)-764-7661 or your veterinarian right away [1][2].
What You Can Do At Home
You can support your dog at home while waiting for veterinary care.
- Pick up stool immediately and wash your hands afterward.
- Clean food and water bowls daily.
- Bathe your dog if the coat is soiled with stool.
- Keep your dog away from other pets and young children until treatment is done.
- Give the prescribed dewormer exactly as directed, for the full course.

Treatment Options Your Vet Will Discuss
Treatment depends on which worm your dog has.
| Worm type | How it is treated | Notes |
|---|---|---|
| Roundworms | Prescription dewormer (often pyrantel or a combination product) | Puppies are treated on a schedule |
| Hookworms | Prescription dewormer | Can cause anemia, especially in puppies |
| Whipworms | Prescription dewormer | Hard to clear, often needs repeat treatment |
| Tapeworms | Prescription dewormer containing praziquantel | Flea control is essential |
| Heartworms | Veterinary treatment, not a dewormer | Prevention is far safer and cheaper |
Some modern products combine several drugs in one chewable tablet. A 2025 field study in the United States tested a chewable containing lotilaner, moxidectin, praziquantel, and pyrantel against hookworms and roundworms in naturally infected dogs [6]. Combination products like this are convenient because they cover multiple parasites at once.
Deworming is not always a one-time event. A 24-month field trial in China used monthly praziquantel delivery to control echinococcosis in dogs, showing that repeated, scheduled treatment is often needed for lasting control [7].
One more caution. Dewormers do not always work perfectly. A study in Portugal found that some common deworming combinations failed to reduce parasite egg counts in shelter dogs, which points to possible drug resistance [5]. If your dog still has worms after treatment, tell your vet. A different drug or a longer course may be needed.
Recovery, Outlook, and Long-Term Management
Most dogs recover well once they get the right dewormer. You may see worms in the stool after treatment, which is normal. Follow-up fecal tests confirm the infection is gone.
Heartworm disease has a longer road. Treatment takes months, requires rest, and carries some risk. Prevention is much simpler and safer.
Long-term management usually means two things: monthly prevention and regular fecal testing. Many heartworm preventives also control intestinal worms, so staying on schedule protects your dog from several parasites at once.
Prevention
Prevention is the most effective part of worm control.
- Give monthly heartworm prevention year-round, even in cold months.
- Use a flea control product, since fleas spread tapeworms.
- Pick up stool in your yard and on walks.
- Wash your hands after handling your dog's waste.
- Keep puppies on the deworming schedule your vet recommends.
- Avoid raw meat diets, which can carry tapeworms and other parasites.
- Schedule a yearly fecal test, or more often if your dog is high risk.

Limitations and When to Contact a Veterinarian
Home care has real limits. Worms need the right drug, and only a veterinarian can prescribe it. Individual cases need a veterinarian, because the right treatment depends on the worm, your dog's age, weight, and overall health.
Call your veterinarian the same day if you notice:
- Worms in stool or vomit
- Diarrhea lasting more than a day
- Weight loss or a potbelly in a puppy
- Scooting or constant licking at the rear
Go to an emergency clinic now if your dog has:
- Collapse, weakness, or pale gums (possible severe hookworm anemia)
- Trouble breathing or a distended belly
- Vomiting that will not stop
- Seizures or tremors after eating something unusual
Call a routine visit if your dog is due for a fecal test, heartworm test, or monthly prevention refill.
If you suspect poisoning from a home remedy, call Pet Poison Helpline at (855)-764-7661 or your vet immediately [1][2].
Frequently Asked Questions
Can I give my dog a human dewormer?
No, do not give human dewormers to your dog without veterinary guidance. The drug and dose are different for dogs, and the wrong choice can cause serious side effects. Your vet will calculate the correct dose based on your dog's weight and health.
Can pumpkin seeds or garlic get rid of worms?
Pumpkin seeds are not proven to clear a worm infection, and garlic can be toxic to dogs. Neither is a substitute for a prescription dewormer. If your dog has worms, ask your vet for the right medication.
How do I know if my dog has worms without a vet visit?
You may see worms in stool or vomit, or notice a potbelly, weight loss, or scooting. But many dogs with worms show no signs at all. A fecal test at your vet's office is the only reliable way to confirm an infection.
Are dog worms contagious to people?
Some worms, including hookworms and roundworms, can pass from dogs to humans. Children and people with weakened immune systems are at higher risk. Prompt treatment and good hygiene reduce the risk for your whole household.
Can heartworms be treated at home?
No, heartworm disease cannot be treated at home. It requires veterinary treatment, and prevention is far safer and less expensive than treating an infection. Give monthly heartworm prevention year-round to protect your dog.
