Prevention and Natural Treatment vs Chemical Dewormers

Certain worms cause more obvious symptoms than others, here are some of them that your dog may manifest when he has worms:

• Diarrhea and/or vomiting, intermittent or frequent
• Fever
• Scooting and/or licking his rear (although scooting may mean something else too)
• Refuse his food
• Being lethargic, his coat may look dull
• Stools covered with mucus (but otherwise look normal)
• Stool with wavy worms or in the form of rice grains.

Keep in mind that some worms can not be seen with by the naked eye.
If your dog’s showing some of these symptoms, you might want to get a faecal sample analysed by your veterinarian.

There are many different deworm drugs and like all medications, they have side effects.
Here are some examples of the adverse drug events from the Food and Drug Administration (FDA).
These are just for the most common active ingredients in de-worming drugs.

*Note that some medications contain more than just one active ingredient.

1. Fenbendazole

It is the active ingredient in some of the most commonly used deworming products:
Panacur®, Drontal Plus® and Safe-Guard®.
The most common side-effects are vomiting, depression/lethargy, diarrhea, anorexia, anaphylaxis, itching and swelling of the face.
126 deaths have been reported.

2. Pyrantel

It is the active ingredient of Drontal® Plus, PRO-Wormer 2®, Nemex®-2.
Side effects include vomiting, depression/lethargy, anorexia.
204 deaths have been reported.

3. Praziquantel

It is the active ingredient of Droncit® and Drontal® Plus.
The side effects include: vomiting, depression/lethargy, diarrhea, anorexia.
13 deaths have been reported.

4. Combination of drugs

Some drug companies associate deworming ingredients with heartworm medicines.
They then market these combinations as preventative products against heartworm and various types of intestinal worms.
Manufacturers recommend using these medications every month.
If you do, you treat your dog unnecessarily for worms that he does not have!
Some of them include Panacur® Plus, Heartgard® Plus, Tri-Heart® Plus, Iverhart Max®.

Foods To Prevent Worms


Fruits and vegetables

Several foods can help make your dog’s intestinal tract less attractive for worms, including:

• grated raw carrot
• watercress
• squash
• fennel
• papaya
• pumpkin

Give at least ½ teaspoon of each vegetable or fruit per 4.5 kg of body weight, twice a day.

Dried coconut

The dried coconut is a dewormer, which means it can help eliminate tapeworms from the body.
Sprinkle on food, giving 1 teaspoon for small dogs, 2 teaspoons for medium dogs and 1 tablespoon for larger breeds.

Apple cider vinegar

A naturally alkaline system kills parasites.
About ¼ to 1 teaspoon of apple cider vinegar added to your dog’s food or water, each day can help maintain one’s alkaline system.

Prebiotics – Probiotics and Digestive Enzymes

Prebiotics & Probiotics help maintain a good balance of healthy intestinal bacteria.
They can strengthen your dog’s immune system and help it fight worms.
Digestive enzymes also provide additional support to the digestive system to help eliminate parasites.
For probiotics and digestive enzymes, follow the dosing recommendations.

Natural Worm Treatments


Remember that none of these herbs should be used excessively.
Do not use more than the recommended amount without consulting your holistic veterinarian or herbalist.

* CAUTION: With the exception of pumpkin seeds and black seeds, none of these remedies should be used during pregnancy or lactation.

Pumpkin Seeds

Raw and organic pumpkin seeds can help prevent or expel worms.
Give ¼ teaspoon per 5 kg of body weight.

Black Seed or Black Cumin Seed

Whole seeds are preferable, but if you use black seed oil, halve the above dose.
Depending on the size of your dog, use ½ to 1 teaspoon of black seeds in the food per day.


Garlic can strengthen the immune system and help fight worms and giardiasis.

In fact, research shows that garlic is as effective as – the toxic chemical – IVERMECTINE.

It also contains an amino acid, Allicine, which is effective against roundworms and hookworms.
Peel and chop the garlic and let it sit at room temperature for at least 15 minutes.
The daily dosage:
• Small dogs up to ¼ of garlic clove 2 times a day
• Medium dogs up to ½ clove of garlic 2 times a day
• Large dogs up to ¾ clove of garlic 2 times a day
• Giant Dogs 1 clove of garlic 2 times a day.

* CAUTION: Do not use garlic if your dog is taking cyclosporine or anticoagulants.
Susan Wynn, Veterinary Herbalist, warns us about Akitas and Shiba Inus because these breeds are more susceptible to the haemolytic effects of oxidants such as N-propyl disulfide found in garlic.


It can calm the intestinal tract when parasites cause discomfort (bloating, gas or cramps).
Chamomile is best used as a glycerine tincture.
Give 0.25 to 0.50 ml per 10 kg of body weight, twice a day.
Give the dye directly into your dog’s mouth or into his water.


Cloves are effective against microscopic parasites such as giardia and coccidia.
Give one pod per 5 kg of body weight once a day, or a small pinch of clove powder in the food.
The freshly ground leaves will kill the parasite eggs.
* CAUTION: Do not give cloves to pregnant females as they can cause miscarriage. Pods can be very toxic if administered in large doses and you should also be careful when using them on small dogs.

Olive leaf

To treat intestinal worms, look for an olive leaf extract containing 12% or more of oleopurine.
Give your dog this olive leaf extract for 8 weeks, in the following quantities:
• 300 mg twice daily for small dogs
• 500 mg twice daily for medium-sized dogs
• 1000 mg twice daily for large and giant dogs.


Acts as both a lymphatic and liquid motor and as a dewormer.
Make a parsley tea using ¼ cup fresh parsley for 1 cup of water.
Heat the water and let steep for about 5 minutes.
Give your dog 1 tbsp. parsley tea for 5 kg of body weight per day for up to 10 days.

* CAUTION: Do not use parsley if your dog has kidney problems.
