Is It Possible To Get Infected With Worms From A Dog

What worms parasitize in a cat

Unfortunately, the number of worms parasitizing in the cat’s body can be stretched into a large list.

Is It Possible To Get Infected With Worms From A Dog

Here are their main types:

  • Nematodes or roundworms. This type of parasite is localized in the intestine of the cat. The most dangerous species are feline toxocaras, hookworms and roundworms. Toxocaras cause toxocorosis, which is usually asymptomatic, but massive infestations of this parasite can lead to the death of the animal. Ankylostoma enters the cat’s body through the soil, during walks and games of the animal on the street.
  • Cestodes or tapeworms. Representatives of this class of worms have a flat ribbon-like body, which is reflected in their name. They are introduced into the intestinal mucosa by the head, which is capable of separating from the body and ejaculating a large number of eggs. This class of helminths includes a broad tapeworm, cucumber tapeworm and other types of tapeworms.
  • Trematodes or flatworms (flukes). This type of worm is capable of parasitizing not only in the intestines, but also in other organs of the cat. This class of worms includes the feline fluke, which can seriously damage the liver of an animal.

However, the listed types of helminths are not transmitted to humans from cats. This can be explained by the fact that many parasites need an intermediate host, since without it their life cycle is disrupted and they cannot develop into an adult. For this reason, helminths are not transmitted directly from cats to humans. A person, of course, can become infected with these parasites, but not from a cat.

Infection with worms in a cat is also dangerous for another reason. During the development of a parasitic infection, animals become aggressive and uncontrollable. They can rush at their owners, scratch and bite. Therefore, at the first signs of inappropriate behavior of the cat, you should immediately take the animal to the veterinarian.

What diseases in humans are caused by feline parasites

Helminths, parasitizing in the body of a cat, cause the following diseases in humans:

  • Ascariasis;
  • Toxocariasis;
  • Giardiasis;
  • Toxoplasmosis;
  • Echinococcosis.


A cat can become infected with roundworms without even leaving the house. Since a person himself brings helminth eggs from the street on shoes, and cats meet their owner and rub against his legs. Thus, ascaris eggs fall on the legs and hair of animals, and then are swallowed by them. Ascaris-infected cat feces are the main source of infection.

Ascaris, once in the human body, cause serious pathological processes. In the larval stage, they are able to migrate throughout the body, causing general intoxication of the body. Only after entering the small intestine, adults are localized in it. An infected person has serious symptoms during the migration of larvae:

  • Stomach ache;
  • Nausea and vomiting;
  • Lack of appetite;
  • Upset stomach: constipation gives way to diarrhea;
  • Unexplained weight loss;
  • Intoxication of the body;
  • Allergic reactions;
  • Decreased immunity.


Infection of a cat with Toxocara cati parasites occurs when the cat walks outside, since Toxocara eggs are in the soil and mix with dust. The eggs fall on the cat’s legs and hair, and then, licking itself, the animal swallows them. A cat, which is always at home, can also become infected with helminths, since street dust enters the dwelling through open windows or is brought into the house with shoes.

The second way a cat gets infected is by eating raw meat and fish infected with toxocara. After all, the larvae of parasites are often found in raw meat, with which the owners feed their pets. Cats eating infected rodents (mice and rats) can also become infected in this way.

Once in the human body, toxocars affect the central nervous system, cause allergic reactions and impairment of the optic nerves. In an infected person, symptoms are observed only at the second stage of the development of the disease, when the migration of larvae begins. During this period, the following symptoms appear:

  • Subfebrile temperature (up to 37.5);
  • General malaise, weakness and fatigue;
  • Stomach ache;
  • Nausea and vomiting;
  • Diarrhea;
  • Rash on the skin;
  • Enlarged liver;
  • Swollen lymph nodes.


Giardia is not a worm, bacteria or virus. It is the simplest unicellular microorganism, one of the most common parasites in cats, dogs, rodents and humans.

Cats become infected with Giardia through contaminated water and food. The cat, washing after using the toilet, swallows cysts (larvae) of lamblia. When enough lamblia accumulates, it develops symptoms of a parasitic infection.

From an infected cat, lamblia gets to a person, and he has the following symptoms:

  • Pain in the epigastric region, in the navel;
  • Nausea;
  • Flatulence;
  • Constipation and diarrhea;
  • Yellow feces with mucus.


Toxoplasmosis is a common disease in domestic cats. A cat can swallow the parasite while walking, eating contaminated food, licking paws after using the toilet. Toxoplasmas are very common in the environment. They are found almost everywhere. A person can become infected from a cat by removing its feces tray, and then not always, but only in cases where the feces have been in the tray for more than a day. As the cysts have to mature.

The symptoms of toxoplasmosis in humans are characterized by their diversity, therefore, diseases can only be identified using serological blood tests. With strong immunity, the disease is completely asymptomatic. Infection of a pregnant woman with toxoplasma is a serious danger, since the parasite affects the fetus, causing serious violations of its organs and systems, as well as people with reduced immunity (HIV infection).


Domestic cats are infected with echinococcosis by the fecal-oral route. Cats are the main host for echinococcus. The parasite gets to them from small rodents (mice, shrews). Maturation of adults occurs in the intestines of the cat, but the stage of maturation of the larvae occurs in intermediate hosts (small and cattle, horses, pigs, humans). Cases when a cat becomes an intermediate owner are quite rare, but they are still there. This occurs when a cat swallows eggs of an echinococcus. If the eggs of this parasite enter the human body, then it also becomes an intermediate host. And in this case, there is a long happy life of the parasite for 20 years.

Echinococcus causes serious damage to the liver, heart, brain or any other organ in which its larvae have settled in a person. The course of echinococcosis is so difficult that it can lead to the death of the patient. The symptoms of the disease depend on which organ was affected by the parasite.

How not to catch worms from a cat

A rare modern family does without a pet. Dogs and cats have long been an integral part of existence for many people. However, do not forget that pets are carriers and carriers of many parasitic infections. And in this sense, they cause irreparable harm to their owners.

Cats are especially dangerous, since they are carriers of a dangerous infection. toxoplasmosis, which affects children and pregnant women. Naturally, any sane person has a question, is it possible to get infected with worms from a cat? Indeed, most often pets live in families where children grow up. Are they a serious threat to their health? Next, we will try to answer these and other questions.

How can you get worms from a cat?

Helminths are transmitted from cats to humans in the following ways:

  • By direct contact with a pet;
  • If the rules of personal hygiene are not followed;
  • Through cat feces;
  • Through cat saliva.

The presence of a cat in the house, of course, increases the chances of infection with helminths of family members. Since the ways of transmission of a parasitic infection are very simple. Despite the fact that the cat is a very clean animal, the constant licking of its fur only increases the likelihood of infection with parasites, since the eggs of helminths are distributed throughout the scalp. In this case, the cat’s tongue is the most dangerous spread of infection. To do this, you just need to pet the cat and not wash your hands. and infection with worms is guaranteed.

The cat litter is a colossal accumulation of eggs. Since females of worms emit hundreds of thousands of eggs every day, they, along with feces, erupt into the external environment. Even regular and thorough cleaning of the litter box does not completely avoid infection. In addition, helminth eggs accumulate in large numbers in the cat’s litter box, and smooth, microscopic helminth eggs easily spread everywhere. Therefore, it is necessary to clean the litter box only with gloves, since the larvae of roundworms can even pass through the skin. The tray itself and the area around it should be regularly treated with a disinfectant.

Avoiding infection is simple, but at the same time difficult. Even washing hands does not always save us from infection, because a beloved pet licks our hands, rubs against our clothes, touches us with its paws and nose, sleeps in the owner’s bed.

For this purpose, it is much more reliable to carry out preventive measures. It is a very erroneous opinion that a cat that does not go outside and the landing does not have helminths.

Ways of infection of cats

Cats have their own ways of infection with helminths:

  • From small rodents (mice and rats), which they eat;
  • Through fleas and flies;
  • When eating raw meat and fish contaminated with helminth eggs;
  • When walking on the street, a cat can pick up helminth eggs, since they are found everywhere: in the grass, in the soil, in the water;
  • Contact with other cats
  • Small kittens become infected through breast milk if an adult cat is infected, however, it is more difficult for kittens to transfer helminthic infection than for adult cats;
  • If the cat drinks water from a puddle;
  • When licking your own fur;
  • Through your feces.

What parasites can be infected from a cat

However, all of the above does not mean at all that a cat living at home cannot become source of infection for humans. The domestic cat is a carrier of the simplest parasites that cause serious diseases in the human body:

  • Giardia, causing giardiasis;
  • Toxoplasma causing toxoplasmosis.

But this list can be continued by representatives of round and tapeworms, which are transmitted to humans from cats:

  • Ascaris (round worm);
  • Toxocars (round worm);
  • Pinworms (roundworm);
  • Echinococcus (tapeworm).

It will seem surprising that this list includes pinworms, which are extremely “humanitarian” parasites. The thing is that pinworms have an amazing rate of maturation of eggs, which are easily dispersed in the environment and settle on toys, underwear, clothes, on household items and on the soft fur of your beloved pet. Consequently, a person becomes infected with pinworms not from cats, but because they are all around us.

Leading a free lifestyle, cats can bring eggs of any parasite into the house, and a person can swallow them. Only now it is worth remembering that the human body is not suitable for all parasites as the main host.

How not to get infected with worms from a cat

In order not to become infected with helminths from a cat, a number of simple rules should be followed:

  • First of all, always wash your hands after every contact with a domestic cat and especially after touching stray animals;
  • Be sure to wash your hands before eating and after using the toilet;
  • From an early age, children should be taught to personal hygiene;
  • The cat should not be allowed to sleep in the same bed with children and adults;
  • Don’t kiss the cat;
  • It is necessary to clean the litter box in a timely manner and do it with rubber gloves, since nematodes can penetrate the skin;
  • It is advisable not to let the domestic cat out into the street, since it will not be able to avoid contact with other animals, contaminated soil, water and earth;
  • You should not teach a domestic cat to raw meat and fish, it is necessary to subject them to high-quality heat treatment, you should not lightly weld the meat, in this case the parasites will not die;
  • It is highly recommended to carry out regular deworming of pets with special anthelmintic drugs;
  • Regularly carry out preventive examinations of the cat by a veterinarian;
  • Disinfect cat bowls and litter box with disinfectant;
  • Children should not be allowed to touch stray animals, since they are the source of the parasitic infection.

Ways of spreading worms

The possibility of infection depends on the conditions in which the animal is kept in the house. Compliance with sanitary and hygienic standards is important here. The dog must definitely walk outside. There she often contacts her relatives. But so the dog can become source of infection and become infected with parasites.

The defeat of the intestinal worms of the dog leads to severe itching. In an effort to get rid of the source of discomfort, the dog will scratch all areas of concern. Many parasite eggs collect on the paws and claws of the animal. Then they spread to the coat and other parts of the body. From here they can be transferred to healthy animals or humans.

Close contact with an infected pet will certainly lead to human illness.

Dog helminths

It is important to know which worms are transmitted to animal owners. To do this, you need to have an idea of ​​the most common types of parasites. Under certain conditions, a dog can easily get sick:

  • Echinococcosis;
  • Teniosis;
  • Dipylidiosis;
  • Diphyllobothriasis;
  • Uncinariosis.

Teniosis is a type of parasitic disease that causes pork tapeworm. The digestive system of an animal is affected, and occasionally a human. The dog can be the middle link in the transmission of the disease to humans.

Dipylidiosis is an infection with a tapeworm called cucumber tapeworm. If the pet has fleas, the parasites can quickly spread from the surface of the coat to the internal organs.

Diphyllobothriasis infects mainly residents of regions where temperate and cold climates prevail. The main source of infection is fish. If you feed a dog such a fish, it will become a carrier of the disease.

An animal can get sick with uncinariosis when swallowing nematode larvae. Another route of infection is through the integument of the skin. Another way is the consumption of unprocessed meat by animals. Among all the listed diseases, the greatest danger to humans is echinococcosis.

In practice, echinococcosis is very rare, since the source of infection can only be the meat of a sheep affected by worms.

Can worms be transmitted from dog to person?

Worms are a species of parasitic organisms living in the body of humans or animals. Many pet owners are interested in whether a person can become infected with worms from a dog.

Unfortunately, the transmission of helminths is possible. Not all worms take root in the human body, but most of them are a potential danger to humans.

Why is infection dangerous?

Pet owners often wonder if dog worms are dangerous to humans. Once in the systems of the human body, they often cause intestinal bleeding. Often, body weight decreases, diarrhea appears, and the anus becomes inflamed. It so happens that helminths that infect dogs find it difficult to adapt to the characteristics of the human intestine. This leads to the migration of larvae. Destruction of a person’s skin or even eyes can occur. For children, it is fraught with blindness.

Precautionary measures

As already mentioned, compliance with hygiene standards is an important safety factor for human health. There are several important rules that pet owners must follow:

  • After communicating with a pet, you need to wash your hands very carefully, because the eggs of worms can get on the mucous membrane and surface of the body.
  • A dog living with people should have its own specially designated place. It is unacceptable to let the pet sleep in the owner’s bed.
  • One should try to avoid contact with the mucous membrane of a four-legged friend. The dog should not, for example, lick the owner’s hands.
  • The animal cannot be fed with raw meat and fish.
  • Wet cleaning of the premises with the use of disinfectants is required at least once a week. Particular attention should be paid to places where the animal spends most of its time.
  • Preventive deworming with the help of special preparations is carried out at least once every six months. If worms are already detected, all family members are treated.

Taking care of your pet’s health is a guarantee of human safety. A dog should be source of only positive emotions for a loving owner.


Nematodes cause an increase in body temperature.

Helminths of the first group are very similar to the human species. The only thing that distinguishes them is their behavior after penetration into the human body.

The most common “uninvited guests” are the Toxocara canis larvae. The risk group for infection with these parasites includes, first of all, children who easily swallow this type of larvae. And also an increased risk of infection threatens veterinarians, dog nursery workers, hunters in contact with dogs, summer residents and gardeners.

Once in the body, Toxocara canis passes through the intestinal wall into the bloodstream, settling in the liver, lungs, brain, eyeballs, kidneys or pancreas. In this case, Toxocar larvae provoke tissue necrosis, allergic reactions, partial or complete blindness, the development of bronchial asthma.

The main symptoms of the presence of toxocar in the body are:

  • Increased body temperature;
  • Various types of skin rashes;
  • Memory impairment;
  • Optic neuritis;
  • Muscle pain;
  • Unreasonable cough;
  • Decreased appetite.

Pork tapeworm

The ultimate goal of the pork tapeworm is precisely the person, since only inside the human body the parasite can multiply.

The reproduction process provokes damage to the walls of the small intestine or teniasis.

Symptoms of teniasis:

  • Severe diarrhea;
  • Significant weight loss;
  • Migraine;
  • Poor or intermittent sleep;
  • Nausea and vomiting;
  • Abdominal cramping.

Pork tapeworm provokes severe diarrhea.


Hookworms, falling on the skin, provoke redness and itching.

Once in the soil, they are able to penetrate the human skin, thereby causing concomitant skin diseases. This is worth remembering for all barefoot lovers, as well as parents whose children regularly play in gardens and parks.

With skin infection, the following are observed:

  • Redness and itching;
  • Small bleeding sores;
  • Allergic reactions.


Echinococcus reproduces in the small intestine.

This is due to their ability to provoke the emergence and development of cysts in the tissues of the lungs and liver. In this case, neoplasms can reach the size of a tennis ball. But the main danger lies in the asymptomatic course of this disease and in the ease of human infection.

Echinococcus also parasitizes in the small intestine of not only dogs or cats, but also wild animals, such as wolves and foxes. Getting rid of this type of parasite during conservative treatment is not possible, therefore, surgical intervention acts as a cure.


Tapeworms can exist in both humans and dogs.

According to medical statistics, almost 30% of adults are carriers of helminthic parasites.

Among organisms of the tapered species, the most frequent participants in transmission from animal to host are:

  • The tapeworm is wide;
  • Pork tapeworm;
  • Echinococcus;
  • Cucumber tapeworm.

Wide tapeworm

Wide tapeworm penetrates the dog through infected meat.

This is one of the largest representatives of its class, in the common people called the bull chain.

It got its name from its habitat. the small intestine and muscle tissue of cattle.

This parasite enters the dog’s body by eating the last meat of an infected cow or calf. Dogs are not scientifically infected with bovine or pork chain individuals, but at the same time they are carriers of this type of helminths, the so-called “intermediate hosts”, capable of transmitting or provoking helminthic invasion.

What worms can you get from a dog

There are parasites that can be transmitted to humans from dogs.

Consider which worms are transmitted from dog to person.

Can a person get infected from a dog with worms?

We know that a dog is man’s best friend since childhood, however, communicating with our smaller brothers, in addition to pleasure and benefit, carries a number of dangers that all lovers and owners of dogs must have an idea of.

Can a person get infected from a dog with worms

And this despite the fact that more than 400 types of helminthic parasites can live in the human body. The dog’s body temperature different from the temperature of the human body, the different acidic environment of the stomach are all factors that reduce the percentage of survival among worms when they enter the human body from the animal’s body.

Most of the helminths get to humans through the ingestion of contaminated food or through the lungs. The most vulnerable group are children, who have a much simpler attitude to the concept of hygiene and have not yet fully formed immune systems. There are 2 main types of helminths that can be transmitted from a pet to its owner: tapeworms and nematodes.

Children are most vulnerable to infection with worms.

Can a person get infected with worms from a dog: how to avoid helminthiasis

Most dog owners do not treat their pets for worms, believing that pets cannot become source of spread of parasitic worms. Unfortunately, every dog ​​is more or less susceptible to helminth infection.

It does not matter at all whether the pet visits the street or not, whether it is in contact with its relatives. Almost all four-legged pets have parasites in their bodies.

Some worms are transmitted from animals to humans, others will never parasitize in humans. Is it possible to get infected with worms from a dog. a question that worries every pet owner.

Dangers of infection

It must be remembered that helminths pose a serious threat to human health, and in most cases a person can become infected with worms from a dog through close contact with a pet.

Helminth larvae can damage mucous organs, cause bleeding, acute inflammatory processes, and cause irreversible changes in tissues.

In young children, worms cause low immunity, as a result of which the child is more likely to suffer from infectious diseases.

In addition, infection with helminthiases from a dog to a person can lead to metabolic disorders, indigestion. Living in a child’s body, the worms feed on nutrients from food, cause allergic reactions, severe poisoning, blockage or intestinal obstruction. When a lot of helminths accumulate, there is a risk of intestinal rupture.

Worms are especially dangerous for pregnant women. Helminthiases provoke miscarriages and premature birth, disrupt the process of fetal formation.

Therefore, a woman who is pregnant should avoid contact with pets or regularly deworm dogs to prevent the possibility of becoming infected with parasites.

Helminths transmitted to humans

There is an opinion that the worms that live in the body of a dog cannot be transmitted to humans. This belief is fundamentally wrong, not all helminths that infect dogs are able to live in the human body, but some types of worms have adapted to life in the human body.

Science knows more than 400 species of various helminths that live in the organs of a dog. Most parasites cannot exist in the human body for one reason: the body temperature of animals is much higher than that of humans. For a full development cycle, worms require favorable conditions, so the human body does not suit them.

Canine parasites that have entered the human body tend to quickly leave an unfavorable habitat, as a rule, through feces. But despite the fact that the worms are removed from the body, they still negatively affect the work of all human organs.

Worms are not always transmitted from dog to person, but helminths that can take root in the human body are very dangerous, because worm infestation causes irreparable damage to health, and in some cases can lead to death. The most common dog-to-human worms are:

  • Cenurosis is a disease caused by a tapeworm. Infection of a person with this disease leads to damage to the spinal cord and brain. A person can acquire the parasite by drinking water or food containing feces from a sick dog. The defeat of the spinal cord causes paralysis of the lower extremities, the brain. vomiting, frequent and severe headache, loss of consciousness, convulsions.
  • Dipylidiosis is a disease caused by a tape parasite called cucumber tapeworm. The worm grows and develops in the small part of the human intestine, while provoking pain in the stomach, constant nausea, increased salivation, itching in the anus. Infection with tapeworms is possible only when a flea patient with dipylidiosis is swallowed, which is the intermediate host of the helminth. If the dog is not treated for ectoparasites, its owner is at increased risk of acquiring the disease.
  • Toxocariasis is a dangerous disease that affects almost any organ of the human body. With the blood flow, the larvae of the round worms are carried throughout the body, getting into the liver, intestines, lungs, and kidneys. Worms can be infected from a dog through contact with an animal, as well as if the rules of personal hygiene are not followed, after communicating with a pet. The signs of toxocariasis are different and depend on the organ in which the helminths are located. In most cases, small children who closely communicate with four-legged pets are infected with helminthic infestation. Toxocariasis is very dangerous for the child’s health, as it can lead the baby to partial or complete loss of vision.
  • Teniosis is a disease caused by pork tapeworm. Worm infestation is transmitted through the consumption of pig meat that has undergone insufficient heat treatment. Most warm-blooded animals, as well as humans, are susceptible to teniosis. The transmission of the disease from dog to person occurs through close contact with a four-legged friend (using one dish for eating, kissing). In the human body, tapeworm prefers to dwell in the small intestine, causing indigestion, allergic reactions, anemia, vomiting, pain in the peritoneal region, severe weight loss.
  • Hookworm infection is a helminthic invasion caused by nematodes (roundworms). Both dogs and humans are susceptible to the disease. The parasite larvae can enter the human body through the skin, and then, through the bloodstream, spread to any organs and tissues of the victim.
  • Echinococcosis. The cause of the disease is tiny tapeworms. Localized on any organ (more often in the lungs and liver), echinococci form cysts containing many worms. Dogs become infected with parasites by eating dirty grass, and then through their saliva they can transmit the worms to their owners. Symptoms of echinococcosis in a person may be completely absent for some time, but most often the patient feels pain in the abdomen, general weakness, vomiting and nausea.
  • Dirofilariasis. the disease is caused by cardiogelminths. Dogs become infected through the bites of blood-sucking insects (most often mosquitoes). In the blood and saliva of a sick animal, there are parasite larvae (microfilariae), therefore, in contact with a pet, a person may suffer from this disease. Signs of dirofilariasis are: headaches, nausea, weakness, pain at the site of the helminth.

Often, children suffer from helminthic invasions, since the child’s body is not yet strong enough to fight diseases. Most often, children become infected with pinworms that inhabit the bodies of pets.

Most infections occur during a child’s visit to a sandbox, where stray dogs and cats love to be.

In addition, the ways of transmission of worms during contact with pets are not excluded, especially if the child is not trained in basic hygiene rules. It is noteworthy that pinworms are able to live only in the body of children, worms cannot exist in the body of an adult.

Preventive measures

When communicating with four-legged pets, each owner must follow the rules of sanitation and hygiene, and also teach his children to these rules. You need to adhere to the following recommendations:

  • After communicating or playing with dogs, wash your hands thoroughly with soap and water, especially before eating food, as the eggs of worms can be transmitted to humans.
  • Due to the fact that many helminths are able to penetrate the dog’s body with the help of intermediate hosts (fleas, mosquitoes, ticks), animals need to be regularly treated for ectoparasites. You can use special collars, insect drops or collars.
  • You should not allow the dog to lick the owner’s face, but if such moments are difficult to avoid, you must immediately wash your face with soap.
  • Any pet should have its own place in the apartment and sleep only there. Many dogs prefer to bask in the bed of their owners, which will inevitably lead a person to infection with helminthic infestation.
  • Every 3 months it is necessary to drive out the worms from the dog, using special preparations for deworming to destroy parasitic worms.
  • Perform a weekly wet cleaning of the entire apartment, using various disinfectants for this. The place where the pet lives is especially carefully treated.
  • You cannot feed the dog with fish and meat that have not undergone heat treatment. Worm infestations are often transmitted through raw products.

Dogs have long entered the human family not as pets, but as faithful and close friends. Most owners of four-legged pets treat their dogs like family members: they take to sleep with them, they let the dog lick plates, and now and then kiss the animal on the nose.

Few people think that with such close communication with a dog, unpleasant consequences can occur. worms. Despite good care and quality nutrition, every animal is susceptible to infection with helminths, and this should always be remembered.

Types of parasites

Not all parasites need a human body for a full-fledged habitat, for some it is not at all suitable. But in the case of dogs, the risks are great, especially when you consider that animals, even without being infected with worms, can be carriers of larvae. On a dog, the eggs “come” into the house, and upon contact with the owner, they migrate to a suitable environment.

There are a number of helminths that, getting to a person, do not take root in his body and die, since the internal environment does not correspond to their needs. For other worms, man is the most suitable “host”, providing their colony with everything necessary. But some parasites can exist only in the human body, and animals do not suit them at all.

There are many intestinal and extraintestinal worms, including tapeworms and roundworms.


This tapeworm is the causative agent of echinococcosis. Adults of echinococcus live in the intestines of canines, both wild and domestic, much less often detected in felines.

The parasite is very dangerous to the human body. When infected with worms, special cysts appear in the tissues of the liver and lungs, which acquire impressive sizes within a short period of time. The disease is accompanied by severe symptoms:

  • Aching or cramping pains in the peritoneal region;
  • The onset of nausea and vomiting;
  • Lethargy, weakness, decreased performance.

In addition, in some cases, the disease does not manifest itself for a long period, which makes it difficult to diagnose it in the early stages of development.

There are several species of these parasitic organisms belonging to the strongyloid suborder. Adults inhabit the intestines of vertebrates. But in order for helminths to develop and reproduce, they require special conditions. For example, ancylostoma duodenale ancylostoma can live only in humans; people infected with worms are also the source of infection. Dogs can develop other types of parasites.

The eggs of the worms appear in the external environment together with the feces of animals, and, if the environment is favorable, they are transformed into larvae. They can penetrate the skin, move through the bloodstream, causing the development of a dermatological disease.


Nematodes, which include 40 species of parasitic worms that can parasitize both in humans and animals, causing the disease dirofilariasis. Infection with parasites occurs when the skin is damaged during bites by blood-sucking insects or when a mosquito, flea or tick infected with a larva from a dog enters the mouth.

The main symptom of the disease is swelling, significant thickening of the site of skin damage. It can then arise, then pass, and also manifest itself in various parts of the body. A person can feel how the helminths move in the seal, often this process is accompanied by severe pain in the area of ​​finding the dirofilaria. In addition, the disease causes general weakness, lethargy, headache, nausea.


Helminth, which belongs to the group of nematodes, which more often affects the body of dogs and other carnivores, is very rarely detected in humans. Penetrating into the body through the skin, provokes the development of uncinariosis. a disease accompanied by dermatological disorders. dermatitis, urticaria.

The main route of transmission is contact-household, helminthic invasion is diagnosed infrequently, this form of helminthiasis can be cured on your own.

Pork chain

This parasite is also called pork tapeworm or armed tapeworm. a tapeworm from the order of cestodes, parasitizing in mammals. Almost any animal, this also applies to pets, can act as an intermediate host in the chain of the life cycle of this parasite. The final link in this process is the colonization of the tapeworm in the human small intestine.

Parasitizing the mucous membrane of the organ, the worm provokes the development of teniasis. This disease primarily causes dysfunction of the digestive system. With teniasis, the following signs of helminthic invasion are observed:

  • Liquid feces with mucous impurity;
  • Decrease in body weight;
  • Vomiting attacks;
  • Insomnia;
  • Headaches;
  • Throbbing abdominal pain.

A blood test reveals a decrease in hemoglobin in the blood.

In addition to tapeworms, a round helminth, a nematode, can also become the causative agent of helminthiasis. This category includes various types of parasites that enter the body through the skin or the mouth. Round worms include toxocar, hookworm, etc.

Cucumber chain

This helminthiasis belongs to the group of cestodoses. tapeworms, parasitizing in the intestinal tissues of various animals, including cats and dogs. The chain grows to a very impressive size. 50-60 cm.It becomes the cause of helminthic invasion. dipylidiosis.

Most often, the disease develops without obvious symptoms. Sometimes it is accompanied by digestive disorders:

  • Soreness in the abdomen;
  • Itching in the anus;
  • General weakness;
  • Increased salivation.

In some cases, animals have vomiting, nausea, sleep disturbances, and there is also a likelihood of allergic manifestations.

The disease dipylidiosis is uncommon. For infection, it is required that an infected flea with an egg of the parasite or the salivary fluid of a sick animal penetrate through the oral cavity into the gastrointestinal tract. often, the disease is diagnosed in children. The parasite that causes it resides in the organ of the final host. With the help of competent therapy, you can completely cure the disease.


These worms from the group of nematodes, which outwardly resemble ascaris, are the cause of a serious helminthic invasion. toxocariasis. In humans, the following forms of the disease can be detected: larval toxocariasis (visceral, ocular type) and imaginal (in the intestine). During migration through organs, toxocara larvae damage the intestinal walls, penetrate into the bloodstream. Thanks to this, parasites are spread throughout the body.

The larvae are covered with a specific film that forms a protective capsule. In such a “cocoon” the parasite can exist for a long time, almost to death, and never matured to an adult. But even without turning into a full-fledged worm, the toxocara larva causes serious harm to the human body, often causing death.

The severity of the disease and symptoms depend primarily on the organ in which the larvae are located. The most severe toxocariasis occurs with damage to the tissues of the eye, liver, lungs. Children are the most vulnerable to this form of helminthiasis, they have a more acute clinical picture, and recovery takes a long time.

Why do dogs infect people with worms

Conventionally, the reasons for the transmission of parasites from animals to humans can be divided into 2 large groups:

  • Worms of infection;
  • Accommodations.

An important aspect is the conditions in which a person lives. a potential carrier, as well as features of his health and physiological nuances. It is worth focusing on the fact that not all parasitic creatures can take root in the human body. But most of the worms that infect dogs are still dangerous to humans, since the structure of the systems and organs of these species does not have significant differences.

It is not for nothing that adults do not stop reminding children of sanitary and hygienic standards. after all, this is the main precaution against being infected with parasites. helminthiasis. Unfortunately, people themselves often neglect them, but in vain. For protection to be effective, it is worth remembering the main points.

Pork tapeworm (Taenia solium)

A parasite of the type of tapeworms. The disease is teniasis (it develops asymptomatically for several years, later the manifestation of vomiting, nausea, diarrhea, insomnia). Man is the ultimate master.

Despite the name, pigs, dogs and other animals can be intermediate hosts. Infection occurs through feces, due to non-observance of basic hygiene rules.

Helminth of this type is very dangerous and multiplies in the gastrointestinal tract, from where it can spread to all body systems, up to the brain. Live in the human body for decades.

Hookworm (Ancylostoma)

They belong to the genus of nematodes. The disease is ankylostomosis (the disease goes away without symptoms, but subsequently manifests itself as itchy skin, inflammation and dermatitis).

The parasites are localized in the small intestine of the dog and are transmitted intrauterinely to the puppy through the placenta and milk, then the larvae come out with feces.

Echinococcus (Echinococcus)

A genus of tapeworms of the order Cyclophyllids. The disease is echinococcosis (it develops asymptomatically for several decades), but the most acute signals and manifestations: nausea, vomiting, general malaise, severe aching abdominal pain.

Echinococcus larvae parasitize the calla lilies of the dog. Infection occurs through close contact or through objects: toys, food, bed. For this type of parasite, man is an intermediate host.

The development is due to the fact that echinococci spread a kind of “cysts” in parenchymal organs, such as the lungs and liver, due to favorable conditions for their existence, then spread to other organs.

Canine Toxocara (Toxocara canis)

Representative of roundworms, genus Toxocara. The disease is toxocariasis (expressed by loss of vision, damage to the central nervous system, pneumonia, cough and vomiting). Formed in the animal’s body in the stomach and small intestine, spread through feces.

Basically, a person becomes infected by contact with soil, where already mature individuals parasitize. Once in the human body, they multiply in the brain, liver, lungs, eyes, forming coated growths, which leads to dire consequences for humans.

How to prevent infection

Preventing infection is not easy. If you decide to have a dog, it takes constant monitoring and a lot of effort.

  • Basic hygiene rules: be sure to wash your hands after walking outside and contact with any animal, trim your nails in time.
  • Wash toys, clothes, bedding, carpets, and anything your dog may come into contact with at least 2 times a week, and wet clean the entire house.
  • Walk your dog only on a leash and exclude contact with stray dogs.
  • Do not kiss the animal “on the lips”, limit close contact with him.
  • Treat the pet’s toilet daily if it is in the house.
  • If you still suspect a dog has worms, use an antihelminthic drug for dogs (Milbemax, Febtal)

Given this necessary knowledge and rules, you will significantly reduce the risk of infection with worms from animals. It is important to remember that most species get to humans through the mouth, so hands and nails are one of the dirtiest places on the human body that must be constantly processed.

Be aware that a dog is not only the most popular and beloved pet, but also source of infection with dangerous worms. Watch your pets, take care of them and you can protect yourself and your loved ones. be healthy!

What common worms do people and dogs get?

Scientists have already investigated a number of common human and animal helminths. They are called common because the parasite in the process of its development needs to change the host, one of them is a person.

Some of the most dangerous parasites are:

Is it possible to get worms from a dog through saliva or hugs

Unfortunately, infection with helminths (worms) from animals is a very common fact in our time. Human infection occurs due to daily contact with a pet.

Can you get worms from a dog? Yes, you can. The eggs of the worms are in the feces, from where they spread to the animal’s fur and then, through hugs, kisses and even a joint sleep with the pet, they pass to the person.

What to do in such a situation? To get started, we recommend reading this article. This article describes in detail the methods of dealing with parasites. We also recommend contacting a specialist. Read the article

Human infection with worms from a dog

The lack of basic hygienic standards leads to the fact that a person becomes infected with dangerous parasites from animals. Due to poor ecology and stress, human immunity is significantly reduced, which leads to rapid infection with helminths from dogs.
