When it comes to protecting your dog from worms, traditional deworming often comes with a host of nasty side effects.

But there's good news for all pet owners: there are natural alternatives that can effectively eliminate worms without harming your dog.

Natural dewormers like pumpkin seeds and black cumin seed are both great options, providing a holistic approach to keeping your dog healthy and worm-free. In this guide, we’ll explore various natural methods to get rid of dog worms. 

Watch For These Symptoms Of Worms In Dogs

Before we get into natural dewormers for dogs, it's worth knowing how to spot worms in dogs in the first place.

After all, recognizing the signs of a worm infestation in your dog is the first step toward effective treatment. Since you often won't be able to see visible worms in your dog's stool, it's crucial to know the other symptoms.

With that in mind, the common symptoms of parasitic worms to watch for in your dog are:

  • Diarrhea or vomiting: Frequent gastrointestinal issues can indicate a worm problem
  • Abdominal pain: Your dog may exhibit signs of discomfort or pain in the abdominal area
  • Fever: An elevated temperature can accompany a worm infestation
  • Scooting: Dogs often drag their rear end on the ground when they have worms
  • Loss of appetite: A sudden decrease in your dog's appetite might be due to worms
  • Dull coat: A lackluster coat can be a sign of nutritional deficiencies caused by worms
  • Lethargy: Reduced energy levels and tiredness are common in infected dogs
  • Dehydration: Worms can cause fluid loss, leading to dehydration
  • Mucus-covered stools: Presence of mucus in your dog’s stool is a warning sign
  • Bloody stool: Blood in the stool can indicate a severe infestation
  • Coughing: Some types of worms can affect the respiratory system
  • Bloating: A distended abdomen is a typical symptom of worms, especially in puppies

Understanding these symptoms can help you act quickly. If you recognize your dog displaying many of them, it's a sign you may need to address an intestinal worms problem and restore your pup’s health.

The Best Natural Dog Dewormers

Finding the best natural dog dewormer starts with a healthy diet that supports a strong immune system.

Your dog's immune system, particularly the IgE antibodies, can effectively attack and destroy worms when properly supported. By incorporating immune support nutrients like zinc, vitamin D, and other essential vitamins and minerals into your dog's diet, you can help maintain her overall health and make her body less hospitable to parasites.

However, diet alone may not always be sufficient to eliminate every worm infestation. That's where the natural foods and herbs below come in. They can offer additional support.

5. Black Walnut

Black walnut is a potent natural dewormer but can be toxic if not used correctly. It’s best to use it under the guidance of a holistic vet, especially if gentler options have not worked.

6. Wormwood

Wormwood is another powerful herb that can be effective against worms but should be used with caution due to its potential toxicity.

Pumpkin seeds contain cucurbitin, an amino acid that paralyzes and eliminates worms from your dog's digestive tract.

Use raw, organic pumpkin seeds, ground, and give ¼ teaspoon per 10 lbs of body weight once or twice a day until the worms are gone.

Pumpkin seeds are safe for pregnant dogs.

Pomegranate compounds help expel tapeworms from the digestive tract.

Add at least 1 teaspoon per 10 lbs of body weight to your dog's meals twice a day.

Fresh carrot, beet, and cucumber juices can make your dog’s intestines less attractive to worms.

Dosage varies by size: small dogs up to ¼ clove twice a day, medium dogs up to ½ clove twice a day, large dogs up to ¾ clove twice a day, and giant breeds up to 1 clove twice a day.

Do not use garlic for pregnant or lactating dogs, or dogs on blood thinners.

14. Apple Cider Vinegar (ACV)

ACV creates a more alkaline digestive system, which is less attractive to parasites.

Use raw, organic, unfiltered vinegar and give ¼ to 1 teaspoon per day in your dog’s water or food.

15. Thyme

Thyme is particularly useful for fighting hookworms. Herbalists recommend using fresh or dried thyme herbs.

Add 1 teaspoon per pound of food to your dog's meals.

Caution: Do not use thyme essential oil as it can be toxic. Avoid using thyme in any form for pregnant or lactating dogs.

16. Parsley

Parsley can be used as a simple natural dewormer. Cook fresh parsley and strain out the solids, then freeze the liquid into ice cubes. Give one cube daily.

Note: Some people worry that flat leaf parsley may be toxic to dogs, but it's usually only in very large amounts. If concerned, use curly parsley instead.

17. Bone Broth

Bone broth promotes digestive health, which helps the immune system combat worms. It’s particularly effective around the full moon.

Add a few tablespoons to your dog’s food or serve as a separate snack. You can also add pure aloe juice for an extra boost.

18. Anti-Worm Food Supplement

You can also create a general worming supplement by combining several natural remedies and natural worm treatments.

Herbs For Pets recommends the following mixture for worms in dogs:

  • 2 parts unsalted, raw pumpkin seeds
  • 1 part garlic powder
  • 1 part fennel seeds
  • 1 part yucca root

Mix the ingredients together and add 1 teaspoon per pound of food daily. Feed this mixture for 5 days, then take 2 days off. Continue until your dog no longer has worms.

Caution: Avoid using this mixture for pregnant or lactating dogs.
