How to Deworm a Dog Naturally – No Harmful Chemicals

There are many different relationships in nature that are mutually beneficial. But there are parasites that are definitely not useful. They can even do harm and this is exactly what dogs and worms do. A dog does not benefit from a worm infestation. But the worms get the nutrients from the dog’s food.

A regular wormer treatment can prevent an infestation. This guide aims to help you understand the different types of worms and how to deworm a dog naturally.

A fecal examination can confirm the suspicion of a worm infestation.

Worms can get into dogs in many different ways. For example, through contact with eggs or larvae that are in the feces of other dogs. This can happen quickly if your dog eats feces from other dogs or animals. The eggs or larvae can also be carried home in shoes without us even noticing it.

In adult dogs, worm infestation can usually not be recognized. But they can have serious consequences in puppies. The puppies are usually infected by their mother, as is the case with the so-called roundworm. It is different with tapeworms. The dogs usually get these when they hunt and also eat their prey. This is dangerous when it comes to the fox tapeworm. Learn more about the different types of worms.

What Worms Are There?

Many types of worms can nestle in our four-legged friends. The risk of a worm infestation naturally depends on a number of factors: age, exercise habits, husbandry and diet. There are the following worms:


This worm is the most common in dogs. They can be up to 20 cm tall, making them one of the largest worms. Puppies in particular are particularly at risk when it comes to roundworm. It can cause diarrhea, vomiting and lack of nutrients.

The consequences: growth disorders, dull fur, worm belly, anemia. It is more difficult to recognize in adult dogs, as the animals usually show no signs. It can only be recognized by the fact that they excrete worm eggs and thus represent a source of infection for other animals.

It is estimated that around 14 percent of the fecal samples in public places are contaminated with roundworms. Even humans are affected and can become infected.

How to Know If Dog Has Ringworm


Lungworm has also been found more frequently for a number of years. The dogs usually become infected when they eat snails, mice or even birds. The pulmonary arteries and the right half of the heart are affected.

It can lead to inflammation of the lung tissue, blood clotting disorders, loss of appetite and reduced performance. It can also cause the dog to die suddenly and unexpectedly. Lungworm infestation can be determined on the basis of a special fecal examination. Blood tests can also help here.


Hookworms are not that common and only grow to 1.5 cm. They nest in the dog’s digestive tract and are excreted through the feces. The worms live in the earth and can penetrate through direct skin contact.

It is also possible that they are absorbed through contaminated soil or objects. Puppies are primarily infected directly through their mother. This worm can cause blood loss, which can be very dangerous for the dog.

Emaciation, fatigue and bloody diarrhea are common symptoms. People can also become infected with the hookworm and cause symptoms, especially in people with a weakened immune system.


These worms attach themselves to the intestinal wall and feed on the dog’s blood.

Bloody diarrhea can occur and, in some cases, very serious complications. The worms are very robust and can remain infectious for years. This worm is a big problem, especially in animal shelters and kennels.

A veterinarian can determine the worm infestation.


This worm is a major problem in the Mediterranean and is mainly transmitted via mosquitoes. However, the spread depends on climatic factors. Due to the constant global warming, these worms can now penetrate into areas in which they have never been detected before.

When you are on holiday with your four-legged friend, you should therefore pay particular attention to this. They are a bigger problem, especially in southern and eastern Europe. The heartworm will implant itself in the heart chamber and the pulmonary vessels and cause considerable damage there. They can be up to 30 cm long. Deworming helps here and kills the heartworms quickly and effectively.

Flea tapeworm

If a dog swallows an infected flea, it can become infected by the flea tapeworm. Usually, no symptoms are apparent and the infection can go completely unnoticed.

One possible sign is what is known as “sledding”. Here the dog will constantly lick its anus. The worm can also be transmitted to humans, but this is rarely the case.

Fox tapeworm

The fox tapeworm occurs everywhere and the main carriers are red foxes, field mice and rodents. A dog can become infected if, for example, it eats an infected mouse. Dogs in particular, which often run freely and unsupervised, are affected. People can become infected, but this is rarely the case.

Dog tapeworm

This tapeworm only occurs in the Mediterranean area and is hardly ever found in this country. In the Mediterranean area, it occurs mainly where sheep are also raised. A human can become infected through direct contact with the eggs.

How to Detect Worms in Dogs

It is not always easy to tell whether the dog has worms. Usually, adult dogs show little or no symptoms. But even animals that show no symptoms can infect other animals or people with the worms.

It is therefore very important that measures are taken against the worm infestation. The diagnosis of an acute worm infestation can be made by the veterinarian, for example by examining the feces. Meanwhile, possible symptoms are:

  • Itching
  • Diarrhea
  • Vomiting
  • Constipation
  • Dull fur
  • Bloated stomach
  • Deficiencies in nutrition
  • Loss of appetite
  • Weight loss

The symptoms are more pronounced in puppies and in immunocompromised animals.

How to Deworm a Dog Naturally Without Chemicals

If the veterinarian finds a worm infestation, the owner receives in most cases a means to fight the worms directly. This promises quick help and usually also ensures quick deworming.

The chemicals contained attack the dog’s body and intestinal flora, especially with constant worming. Our recommendation is, therefore: natural wormer cures with herbs from nature, completely free of chemicals. With this recommendation, we do not want to make any promise of effectiveness or equate the effectiveness of natural deworming with that of chemical tablets.

However, many dog ​​owners are constantly looking for a natural product to bypass the chemical pill. We will show you below how this could be done.

Simply mix the natural product with the food and your dog will be supported naturally and appropriately in de-worming. We recommend the FourGuard Herbal Parasite Formula from Natural Wonder Pets:

How does the FourGuard Herbal Parasite Formula work? The organic herbs contained are supposed to create an environment that worms are reluctant to colonize. It can therefore also be given preventively. It is said that worms are most active, especially during a full moon. Accordingly, a dose of the formula can be started, for example, one day before the full moon.

How to Tell If your Dog's Lymph Nodes are Swollen

The FourGuard Herbal Parasite Formula supports the dog’s body preventively and in the event of acute worms.

  • no chemical additives
  • only natural raw materials
  • no preservatives
  • 100% organic herbs

But Natural Wonder Pets, the manufacturer, informs: If the worm infestation is severe or persistent, please consult your vet first. That’s right, because a stubborn worm infestation is usually treated better and faster by the veterinarian with chemical drugs. A fecal examination can diagnose a worm infestation.

How Often Should a Dog be Dewormed?

If you want to protect your dog, you should always take consistent action against worms. The deworming preparations available from the veterinarian are suitable for this. Only regular wormer cures can minimize the risk of infection for dog and owner.

However, it is not always necessary to resort to chemicals, because natural products can also protect against worm infestation or be given as a supplement. Many dog ​​owners use this as a preventive measure. In the case of a stubborn worm infestation, going to the vet is probably the right choice.

Worming has no long-term effect and should therefore be done regularly. It is usually recommended four times a year, i.e. every three months. Regular worming is also important for puppies. Some owners even do it monthly to be on the safe side. Especially with monthly wormer cures, we would not recommend a permanent supply of chemicals.

The vet can help and devise a special plan for deworming. Protection against ectoparasites can also be administered together with the wormer. To do this, however, you should visit the vet and get extensive advice.

Would you like to spare your four-legged friend the chemical pill and only act in an emergency? If you suspect a worm infestation, simply contact your veterinarian and have the stool examined. Such a test is usually done quickly.

If the result is positive, you can fight the worms with the stubborn but effective chemical. If the test is negative, you have saved your dog an unnecessary chemical tablet. The intestinal flora and thus the health of your dog will thank you.
