If the dog has worms what are the symptoms

Treatment of helminthic infestations in dogs

Helminths in dogs are very dangerous and require immediate treatment of the four-legged pet. If you suspect a worm infection, you should contact your veterinarian.

Only a doctor can accurately determine the type of parasite and prescribe an effective treatment that can remove worms in a dog. Self-administration of antihelminthic drugs can lead to severe poisoning and death of a pet.

Veterinarians advise using the following drugs for helminths:

  • Kaniquantel is an effective anthelmintic drug that provides gentle treatment. Produced by German manufacturers. It differs from many products in the absence of side effects and an acceptable price. Has a wide range of actions.
  • Prazitel. has a destructive effect on any worms. Approved for puppy therapy.
  • Drontal plus. has a powerful destructive effect on tape parasites, but is not effective in combating helminth larvae.
  • Milbemax. fights round and tape parasites.

All means that destroy worms are produced in several versions: tablets, suspensions, pastes, drops. The drug Bars for worms for dogs, produced in the form of drops on the withers, is in special demand. The medicine is easy to apply and protects the animal from worms for a long time.

It is not safe to treat a dog at home using folk remedies. Most medicinal plants used to get rid of worms cannot completely rid the animal of parasites. In addition, self-medication of pets threatens to turn into serious poisoning, therefore, the therapy of helminthic invasions should be carried out only by a professional.

Before using any medication aimed at combating worms, you must first remove fleas from the animal. If you neglect this rule, the effectiveness of therapy is sharply reduced. In order to cure a dog of ectoparasites, various shampoos, drops, sprays and collars are used.

The tablets used for the destruction of worms are given strictly according to the weight of the animal. Pre-fasting is usually not required. The drug is finely crushed, mixed with a treat (food, minced meat) and given to a four-legged friend. After 10-14 days, the treatment for helminths is repeated (to destroy the larvae hatched from the eggs). The deworming procedure is carried out once every 3 months.

Symptoms of worms in a dog

Any owner of a four-legged friend should know the signs of helminthic invasion that has developed in a pet. The symptoms of worms in dogs are as follows:

  • Dramatic weight loss. Parasitic worms suck out all the nutrients from the dog, as a result of which the animal’s body becomes depleted.
  • Frequent rumbling in the abdomen, an increase in the volume of the abdominal cavity. Worms in dogs, such as roundworms, cause similar symptoms.
  • Frequent vomiting. It occurs mainly when dogs are affected by tapeworms.
  • Prolonged diarrhea. Indicates infestation with whipworms or nematodes.
  • Blood and mucus in feces. Happens when dogs are affected by hookworm.
  • Skin rash, dullness and hair loss. It is considered a characteristic feature of round helminths.
  • The presence of white moving segments in the feces of the animal, similar to rice or cucumber grains. In this case, it is not difficult to determine that the dog has worms (cestodes).
  • Painful sensations and itching in the perineum. The animal is constantly trying to ride the pope, lick the anus. This behavior indicates the characteristic signs of worms in the dog.
  • Pallor of the mucous membranes of the eyes and mouth. A dog’s loss of nutrients leads to anemia.

In dogs of small breeds, helminthic invasions are more severe than in large relatives. Most decorative pets do not tolerate antihelminthic drugs well, therefore, pets need to be treated only under the strict supervision of a veterinarian.

Heart parasites are difficult to identify. You can find out that a dog has worms if symptoms such as:

  • increased breathing, attacks of shortness of breath;
  • enlargement of the abdominal cavity;
  • excruciating cough;
  • strong weakening of the body;
  • sudden hair loss.

The heartworm is dangerous because all the symptoms of its presence appear only when the disease has become widespread and it is no longer possible to save the dog.

Worms in dogs. causes, symptoms, treatment and prevention

Any pet, regardless of whether it is on the street or leads an exclusively domestic lifestyle, in most cases is already infected with helminths. These parasitic worms are present almost everywhere: in puddles, ditches, on the grass, in the ground, in fish and meat products.

Many dog ​​owners, unknowingly, are carriers of parasites. Upon returning home from the street, most people do not seek to wash their street shoes, but, as a rule, leave them in the hallway. Dogs. lovers of gnawing, sniffing or licking the master’s shoes, and along with the dirt, helminth eggs enter the body of the pets.

How to tell if your dog has worms

Worms in dogs are a very common problem that needs to be addressed as quickly as possible. Parasitizing in the body of an animal, helminths not only suck out all useful substances from the dog’s body, but also cause severe intoxication, often ending in the death of the dog.

Deworming is the most effective way to combat parasites, protecting not only the animal, but also its owners from worms. Not a single veterinarian will allow an animal to participate in exhibitions, mating, and will not undertake to vaccinate a four-legged friend if the dog is not treated for worms before vaccination.

Ways of infection of dogs with worms

All dogs, regardless of age and breed, are susceptible to helminthiasis. Sometimes it is difficult to understand that a dog has worms. In some cases, the invasion may remain asymptomatic for a long time. Small puppies and adolescent dogs are harder than adult relatives to endure helminthic diseases. The presence of worms in the body can be triggered by different ways of penetration of parasites:

  • Hematogenous. Some parasites are transmitted to dogs through insect bites. Helminth larvae enter the bloodstream of the animal and then spread throughout the body.
  • Oral. The eggs of parasitic worms enter the dog’s body through direct contact of the pet with sources of infection (feces of sick animals, food, soil, standing water).
  • Intrauterine. A pregnant bitch is capable of transmitting helminths to her offspring. The most common disease transmitted from mother to fetus is toxocariasis.

Types of worms in dogs

Experts know many types of worms that parasitize inside the body of pets.

Some worms in dogs live and multiply in the digestive tract, provoking diseases of the internal organs and causing severe exhaustion or chronic diarrhea in the animal. Some types of helminths prefer to dwell in the organs of the cardiovascular system and lungs, leading to disruption of the heart, the development of pneumonia, and a painful cough. Most worms that infect the body of pets pose a real danger to human life, so it is important to know what worms look like in dogs.

There are 3 groups of parasitic worms:

  • Nematodes or round helminths.
  • Cestodes or tape parasites.
  • Trematodes known as flatworms.

In nature, there are more than 80 varieties of roundworms, but not all parasites can live in a pet’s body.

Nematodes have a round (spherical) body shape, for which they got their name.

The most common helminthic infestations caused by round worms are:

  • Dirofilariasis. The causative agent of the disease is a white worm, females of which reach a length of 15 cm, and males. no more than 5 cm. Mosquitoes serve as intermediate hosts of the helminth. The larvae (microfilariae) of the parasite enter the dog’s body through the bite of a blood-sucking insect, then rush to the main muscle, the heart, with blood flow. Living and actively multiplying in an organ, worms lead to disruption of its work. Gradually, all the cavities of the main muscle can be filled with helminths, which is why the animal always dies. Dirofilariasis refers to a very severe invasion, since in the early stages of the development of the disease, all signs are similar to heart failure, and an incorrect diagnosis can cost the dog’s life.
  • Toxocariasis. The disease is caused by 20 cm helminths with a light yellow body color. After entering the dog’s body, the larvae of the worm enter the bloodstream and are carried to the vital organs of the animal (first to the liver, then to the heart and lungs).
  • Ascariasis (toxascariasis). The parasitic worms have a body length of about 8 cm and are light yellow. Roundworms prefer the intestines, gallbladder, liver and esophagus of the dog for their habitat. Infection with ascariasis occurs mainly in places of mass congestion of dogs (walking areas). The lack of treatment for the invasion will soon lead to the death of the animal.
READ  Is It Possible To Get Infected With Worms From A Dog

Cestodes are considered the largest parasitic worms. Among the people, tapeworms are called tapeworms, since in appearance their body looks like a chain consisting of links.

Some adult worms are more than 10 meters long. The parasite is equipped with a scolex (oral apparatus) and hooks, thanks to which it literally pierces the organs of its victim. The body of the tapeworm consists of many segments (segments). In each of the segments, the maturation of the eggs of the parasite occurs.

Together with feces, the segments leave the dog’s body, enter the external environment, and dry out under the influence of oxygen, leaving behind a large number of eggs.

Dogs become infected by the invasion only through intermediate hosts (river fish, amphibians, blood-sucking parasites, rodents). Eating an infected animal, insect or fish, the dog swallows the parasite larva along with food.

Once in the gastrointestinal tract, the larva is securely fixed on the intestinal walls, actively feeds, grows and after a short period of time reaches maturity.

Tape worms in dogs are dangerous because when they are massively accumulated in the intestine, they form a kind of tangles, leading to a complete blockage, and then rupture of the organ.

Cestodes cause the following diseases:

How do you know if your dog has worms? 5 symptoms

  • Diphyllobothriasis. The disease is caused by long tapeworms, their body length can be more than 10 m.Dogs become infected by eating raw fish, in the body of which the helminth larva develops.
  • Dipylidiosis (cucumber tapeworm). The causative agent of the disease is a tape parasite with a body length of 1.5 m. Every day, the worm rejects its segments containing eggs. The intermediate host of the helminth is a blood-sucking insect (in most cases, fleas). A dog has worms when a flea is accidentally swallowed.
  • Echinococcosis. The culprit of the disease is a tiny tapeworm, with a body length of no more than 0.5 cm. The mouth apparatus of the helminth is equipped with many hooks that cause severe trauma to the intestinal walls. Echinococcosis affects not only dogs, but also other animals, including agricultural.

Trematodes differ from other helminths in a small flat body, with the help of which they stick to vital organs (lungs, intestines, pancreas, liver). Flukes feed on lymph, blood and mucus.

Infection of dogs occurs when eating raw fish, frogs, as well as during contact with the feces of sick animals. Trematodes cause the following diseases:

  • Paragonimiasis. Flukes have an egg-shaped body, the length of which is no more than 1.3 cm.The intermediate hosts of the helminth are crustaceans.
  • Alariosis. The length of the parasite is no more than 4 mm, intermediate hosts are amphibians.
  • Opisthorchiasis. The parasite is small (about 4 cm). Worm larvae can be found in raw fish, swim in fresh water.


The basic rule for the prevention of helminthiasis is the regular prevention of worms in dogs. Animals are treated for worms before each vaccination, viscous, participation in the exhibition. In addition, procedures such as neutering and castration should also only be carried out after the dog has been treated for parasitic worms. The following rules will help to significantly reduce the possible disease with helminthiasis:

  • feed the dog only with products that have undergone heat treatment;
  • regularly fight fleas;
  • do not visit places of large concentrations of dogs;
  • every time, walking with a pet, put on a muzzle on the dog (to prevent contact with the feces of sick animals, drinking from puddles);
  • avoid communication of a pet with homeless relatives.

Worm infestations are dangerous not only for animals, but also for people living in the same apartment with a dog. Only timely deworming of a four-legged pet, carried out on a quarterly basis, can prevent the development of diseases. For any signs of helminthic invasion, it is necessary to show the pet to a veterinarian who will select the most effective and safe drug for the animal.

Oral tablets

Here are the most popular dog worm pills:

  • Milbemax. Affects all types of nematodes and cystodes. Active against sexually mature individuals and larvae.
  • Drontal. Preparation for adult intestinal worms.
  • Vermox.
  • Envire. Complex preparation, which includes pyrantel, praziquantel, febantel. The combination of these substances allows you to simultaneously block the vital activity of roundworms, cause muscle spasm.
  • Kanikvantel plus is used for combined helminthiasis.
  • Azinox plus. It is used against nematodes.
  • Febtal combo. Works on several types of worms.

The most popular remedy for helminths is tablets.

Nematodes (or roundworms)

In nature, there are more than 80 species of these worms.

In the body of dogs, the parasites are mainly the following:

  • Toksakars are long and light-colored worms that enter the dog’s body in the form of eggs and develop in it to adults. Are the causative agents of toxocariasis disease.
  • Toxacarides are small worms that develop in the intestines.
  • Hookworms. their individuals are 2 centimeters long, feed on the blood of an animal.
  • Dirofilaria. enter the body through an insect bite. Live in the heart and lungs of an animal, lead to the development of dirofilariasis.

worms, symptoms

Roundworms or nematodes are the most numerous and most common type of helminth.

Symptoms of worm infestation

It is possible to suspect infection of a dog with helminths by the manifestation of the following characteristic signs:

  • Alternating constipation and diarrhea.
  • Weight loss with increased appetite.
  • Difficulty swallowing.
  • Licking the anus and “rolling” the animal on the floor to eliminate itching.
  • Presence of skin rashes.
  • Admixture of blood, mucus in feces.
  • Deterioration in the appearance and general condition of the dog (lethargy, lethargy, dull and shedding hair, dandruff).
  • Cough, shortness of breath.
  • In small puppies, additionally, bloating, protruding ribs, and loss of appetite begin. Helminthiasis can cause rickets and a general delay in physical development. The puppy stops growing.

Important. In the early stages of infection, helminthiasis is often asymptomatic. The visual absence of parasites in the feces is not evidence of their absence.

Ways of infection with helminths

It is almost impossible to completely insure a dog against helminths entering its body. But you can reduce the risk of infection with helminthiasis if you provide for some pathways for the eggs to enter the body and limit this possibility.

Important. Animals with weakened immunity are most susceptible to the development of helminthiasis. The probability of infection does not depend on the age of the animal.

Worms penetrate the internal organs of the dog as follows:

  • Through contaminated foods. Eating food contaminated with eggs or licking objects outside is the most likely route of infection. Helminth larvae can be kept in water from puddles, open reservoirs. Eggs are attached to a person’s shoes, grass around the house.
  • Insect parasites are carriers of worms. It is no coincidence that, having found fleas in a dog, veterinarians advise to immediately deworm the animal. Fleas place the eggs of the flatworms on the dog’s fur, and when licked, they enter the intestines. Dirofilariasis a dog becomes infected through a mosquito bite.
  • Adult helminths are transmitted from mother to puppies while they are still in the womb or during the period of breastfeeding. Therefore, before mating, the female is recommended to carry out treatment for worms.

Helminth eggs persist in the environment for a long time, so most often the dog becomes infected through water from puddles or food picked up from the ground.

Types of worms in dogs

Worms are deadly parasites that invade and spread throughout a dog’s body. Parasites live off the nutrients that enter the animal’s body, and at the same time release toxins into the blood and tissues of the dog. A large number of parasites can lead to intestinal blockages, which leads to the death of the dog. Reproduction of parasites in the liver, lungs, heart disrupt the work of organs and can lead to their rupture.

Helminths develop in the dog’s body, feed on tissues, release toxins that poison the animal’s body.

Diagnostics and treatment of helminthiasis

Before starting treatment for helminthiasis, it is necessary to consult with a veterinarian and find out which parasite has settled in the dog’s body. It is not worth solving the problem on your own, as you can aggravate the situation and not rid the dog of parasites.

READ  When a pregnant dog has milk

To determine the type of helminth, feces are analyzed. Thus, the type of intestinal parasites is determined. The presence of heartworms in the body is determined by a blood test.

Before prescribing treatment, the veterinarian will examine the pet’s feces and blood and determine which helminth has settled in his body.

After the diagnosis, treatment with drugs for worms is prescribed. Anthelmintic drugs have different effects on parasites: they interfere with their nutrition, cause paralysis. Only a specialist can determine which particular type of medicine will affect a particular type of helminths.

Modern industry produces several types of anthelminthics.

Rules for deworming dogs

For the successful destruction of worms, you should strictly follow the instructions that come with the drug. The main rule is compliance with the recommended dosage. Feeding pills to the dog is a challenge. They can be hidden in a delicacy: minced meat, butter, cheese, sweetness.

You can arrange a game in the form of catching a pill. With the help of a companion, you can throw the dog’s head back and place the pill in the throat. Then the throat is stroked so that the pill goes into the stomach.

You should also adhere to the following rules:

A tablet for worms can be hidden in a dog’s favorite treat or use a special syringe.

  • On the day of processing, dairy products are excluded from the dog’s diet.
  • The remedy is given to the dog on an empty stomach, in the morning.
  • Before using the antihelminthic drug, the pet is given an immunostimulant, for example, Hemobalance.
  • A few days before the antihelminthic treatment, the animal’s hair is treated from fleas and ticks.
  • If the dog vomits after drug administration, re-treatment is possible only after 2 weeks.
  • The release of saliva during deworming, an increase in pupils in a dog is a sign of intoxication, the dog needs to be given an absorbent.
  • After deworming, the dog should have a bowel movement no later than 8 hours later. If this does not happen, the pet needs to be given a laxative.
  • After 10 days, the anthelmintic treatment must be repeated.
  • Antihelminthic drugs are quite toxic, so during their use, the dog needs to be given medications to protect the liver.

Important. During the worming period, the dog should constantly have fresh water in the bowl, since the drugs cause severe thirst, and dehydration is possible.

Treatment of the animal

Treatment is prescribed only based on the diagnosis. There are broad Spectra drugs, but they have more side effects and contraindications. It is recommended to give the medicine to the animal in the morning, adding it to food or separately. Modern drugs do not require laxatives or adsorbents to remove dead parasites. But in some cases, when side effects appear, the pet needs to be given activated charcoal or Enterosgel.

Before starting treatment, it is necessary to treat the dog from external parasites, as they are often carriers of worms.

Cestodes (tapeworms)

Cestodes are the largest parasitic worms. Their length can reach 10 m. They are also called tapeworms for their specific appearance. Their body resembles a chain with many links or individual fragments. Any fragment can become source of infection, as it contains many eggs.

Cestodes are tapeworms, they are long and flat. Their oral apparatus is equipped with suckers with sharp hooks that bite into the walls of internal organs. Infection occurs only through intermediate hosts: fish, meat, blood-sucking insects. Once in the dog’s body, cestodes grow rapidly. When large, they can lead to intestinal blockage or rupture.

Tape parasites cause several diseases in dogs.

  • Diphyllobothriasis is caused by the broad tapeworm parasite. The length of some individuals reaches 9-10 m. It lives in the intestines, sucks blood, causing anemia. Enters the dog’s body through raw fish.
  • Dipylidiosis is caused by cucumber tapeworm. The parasite grows up to one and a half meters. Many eggs are excreted in the feces of an infected animal every day. They enter the dog’s body through blood-sucking insects.
  • Echinococcosis causes a small helminth. echinococcus. Its length is only 0.5 cm. The parasite settles in the intestine, severely damaging its walls. This quickly leads to the death of the dog. Infection occurs through raw meat and offal. Can be transmitted to humans.
  • Cenurosis is a rarer disease that causes brain damage. The larvae are transmitted through contaminated water, soil, grass. They can be found on the animal’s fur, in the mouth. The larvae settle in muscle tissues, lungs, abdominal cavity, penetrate into the brain.

Infection routes

Many are convinced that proper pet care protects them from infection with worms. And the owners of lap dogs, who do not go out, believe that they cannot have parasites. But in fact, any pet can get infected. After all, eggs of worms are everywhere. They are on the ground, in plants, in water, and even in the air. The larvae enter the animal’s body through raw meat or fish, from human shoes.

These parasites are very tenacious, adapting to any conditions. Eggs outside the host’s body can be on objects, on the ground for up to 6 months. They can be carried by cattle, fish, fleas, mosquitoes.

The main ways of infection with worms are as follows:

  • oral. through the mouth of an animal;
  • transmissible. with a bite of blood-sucking insects;
  • intrauterine. to puppies from a sick bitch.

A pet can become infected by swimming in a pond, playing in the grass with a stick or ball, communicating with infected animals.

What worms can you get from a dog

A person can easily become infected with worms from a pet. After all, the larvae of worms are often found on the dog, its bedding, paws. She can carry them to furniture. They enter the human body from unwashed hands.

Not all helminthiases settle in humans. But there are some parasites. Dogs can become infected with toxocariasis, echinococcosis and some other pathologies.

Types of helminths

All worms that infect a dog’s body are divided into three groups: nematodes, cestodes and trematodes. Most worms are intestinal parasites. They settle in the digestive tract, feeding on the food entering there. But they can infect other organs: kidneys, liver, lungs, heart. In many cases, such pathologies, without treatment, lead to the death of the dog.


If the parasites have settled in the lungs, they quickly lead to the development of respiratory failure and death of the dog. Therefore, you need to know the symptoms of pulmonary worms:

  • nasal discharge, sneezing;
  • cough;
  • labored breathing;
  • anemia and wasting;
  • hair starts to fall out.


The most difficult is helminthiasis, in which parasites settle in the blood vessels that go to the heart. This leads to their blockage and death of the animal. It is important to know how to detect the disease in time. The following signs are noticeable:

  • shortness of breath, shortness of breath;
  • dry cough;
  • slowdown of the pulse, arrhythmia;
  • swelling;
  • weakness;
  • convulsions;
  • emaciation.

In many cases, treatment for heartworms starts too late to save the dog.


Some nematodes and flukes take up residence in the liver and bile ducts. In this case, the following symptoms arise:

Caniquantel plus

Caniquantel Plus is a complex broad Spectra drug with a fairly serious composition. Active ingredients: praziquantel and fenbendazole.

  • Trematodes (flukes).
  • Cestodes (flatworms).
  • Nematodes (roundworms).

Contraindications: pregnancy (at any time), weakened or exhausted condition, up to 3 weeks of age.

Method of use: tablets are introduced into the morning feeding, accumulated in their natural form or drunk in the form of an aqueous suspension. Immediately after taking the drug, the formation of foamy saliva can be observed, which disappears within a few minutes.

The dosage of Kanikvantel is uniform. 1 tablet per 10 kg. body weight. Many veterinarians recommend choosing other drugs for the prevention of worms in puppies, since the dose of Caniquantel is difficult to accurately separate.

Features of use: for prophylactic use, the drug is taken once every 2-3 months. When treating advanced invasions, the drug is taken 2-3 times at intervals of 5-7 days. During the entire treatment, the dog’s excrement must be removed and disposed of.

Side effects: occur extremely rarely, with individual sensitivity or dose overstatement by more than 4 times. Studies have not revealed a breed tendency to sensitivity to drug components.

Worms that affect the organs of the dog (except the intestines)

The most hidden and dangerous parasites do not live in the intestines. Do not underestimate intestinal parasites, flatworms can live for 5-10 years and grow to incredible sizes, but they can be detected early. Parasites in organs can be noticed only when they cause tangible harm.

All worms that parasitize a dog’s organs develop in the body of the intermediate host. To protect your pet from unwanted neighbors, you need to:

  • Boil fish and seafood before feeding.
  • Protect your dog from midges, flies, mosquitoes, mosquitoes.
  • Do not let your pet come into contact with stray animals.

Again, the only surefire control is regular prophylaxis and taking precautions.

The most common fluke parasites can live in a dog’s body for 5–6 years and parasitize unnoticed. The problem is that at the time of detection of worms, they will cause irreparable harm to the body.

Alben and Alben C

Alben is a broad Spectra anthelmintic drug. When working with the drug, you need to pay special attention to dosages, since side effects appear sharply and rapidly.

The drug is available in two commercial forms:

  • Alben. active ingredient albendazole.
  • Alben C. active ingredients: azinox and albendazole.
  • Nematodes. all stages of development.
  • Cestodes. all stages of development. Trematodes. adults only.

Note! Alben is intended for the prevention of parasites in rural animals, therefore its use for dogs is not approved by many veterinarians. Practice shows that owners rarely manage to accurately calculate the dose for small animals.

  • Nematodes. all stages of development.
  • Cestodes. all stages of development.

Contraindications to the use of Alben C: age less than 3 weeks, weight less than 2.5 kg, pregnancy and lactation period. The drug is used only under the supervision of a doctor if the animal is exhausted, over, or recovers from an infectious disease.

Method of use: in the morning on an empty stomach on the root of the tongue, with a little food or water. The occurrence of frothy salivation after the application of an aqueous suspension is considered an expected side effect that goes away without intervention.

  • For dogs weighing more than 2.5 kg, the dose is calculated from the ratio of 1 tablet per 5 kg of body weight.
  • If the dog weighs less than 2.5 kg, 1 tablet is crushed and dissolved in 10 ml of water. The resulting suspension is dosed according to the principle of 1 ml per 1 kg of body weight.

Features of use: when using an aqueous suspension, it must be thoroughly shaken immediately before drinking, since the crushed tablet quickly precipitates. For the purpose of prevention, dogs are treated once every 2-3 months. In the treatment of advanced helminthiasis, Alben C is used only under the supervision of a doctor.

Side effects: with strict adherence to dosages, no negative symptoms are observed. In case of an overdose, the dog quickly develops a clinical picture of intoxication. The condition is relieved by adsorbents and plenty of drinking.

Azinox Plus

Azinox Plus is a complex drug for worms in dogs. Active ingredients: praziquantel and tetramisole hydrochloride.

  • Nematodes at all stages of development.
  • Cestodes at all stages of development.

Contraindications: weakened and pregnant animals. Puppies and nursing dogs can be given Azinox Plus no earlier than 10 days after giving birth, provided that the litter is developing normally and the mother is recovering at an adequate rate.

The dosage of Azinox Plus is calculated based on the proportion of 1 tablet per 10 kg of body weight. Due to the complexity of dosing, in the prevention of worms in puppies, the drug is used with extreme caution.

Features of use: for the prevention of worms in urban conditions, Azinox Plus is used every 2 months. If the dog lives in a village or on a farm, the treatment is carried out every 30-45 days, depending on the activity of the parasites and their carriers.

Side effects: are extremely rare and only in case of significant overdose. Azinox Plus is considered one of the safest drugs for dogs.

In a lactating dog

Worms in a nursing dog are dangerous for both the mother and the offspring. Penetrating (in the form of eggs and larvae) into the mammary glands, the parasites migrate to the puppies, which affects their health almost immediately. In addition, the thin, delicate tissues of the puppy’s intestines often cannot withstand stress. The intestinal wall breaks, the puppy begins peritonitis and sepsis, then death occurs.

What to do if the veterinarian has established a helminthic invasion in a nursing mother.

  • Despite the high chance that the puppies are already infected, they are taken away from the mother for prophylaxis.
  • Babies are fed milk replacer for 4-7 days (depending on the choice of drug), since the milk will contain toxins.
  • For puppies, before reaching the age of 1-2 months or gaining weight up to 1-2 kg, preventive measures to eliminate worms are strictly not recommended.


Troncil is a combined drug for the treatment of mixed types of invasions. Active ingredients: pyrantela embonate and febantel.

  • Round worms.
  • Flat worms.

Contraindications: age up to 6 weeks, weight up to 2 kg, pregnancy, lactation, exhaustion. The drug is contraindicated in sick and recovering animals.

  • Dogs weighing from 5 to 10 kg. 1 tablet.
  • Dogs weighing from 10 to 20 kg. 2 tablets.

Features of use: before using the drug, no diet or other preparation is required. With advanced invasions, repeated treatment is carried out after 7-10 days. For dogs weighing less than 2 kg, treatment is carried out only under the supervision of a veterinarian.

Side effects: manifested with increased sensitivity to the active ingredients of the drug. Symptoms are mild and go away spontaneously. Hypersensitivity is indicated by: drooling, nausea, vomiting, apathy.


Dironet is a complex remedy for worms in adult dogs. Dironet is one of the most popular drugs in regions with an increased risk of dirofilariasis infection. Virgin substances: pyrantela pamoate, praziquantel and ivermectin.

Note! For the treatment of puppies and miniature dogs, Dironet is available as a suspension.

  • Cestodes at all stages of development.
  • Nematodes at all stages of development.
  • Dirofilariasis at the stage of microfilariae.

Contraindications: individual sensitivity to active ingredients, age less than 3 weeks, pregnancy and rearing period. The drug is not recommended for dogs of the collie, sheltie, bobtail breed due to the tendency to individual intolerance.

Features of use: Dironet is recommended to be used once a quarter for the prevention of helminthiasis. With the prevention of dirofilariasis, the frequency of treatment can be increased. When treating advanced invasions, the treatment is repeated 2 times with a frequency of 7-14 days.

Side effects: rarely occur, against the background of individual intolerance. If an allergic reaction occurs, the drug is stopped, the condition is alleviated with antihistamines. In case of an overdose, there is apathy, nausea, vomiting, impaired nervous activity.

Worms in dogs

Modern methods of treatment

As a rule, the treatment of helminthiasis is carried out with the help of various antiglust preparations (tablets, suspensions, drops on the withers). So that after taking the medicine, the dead parasites completely leave the dog’s body, it can be given a mild laxative. Also, veterinarians often prescribe drugs that prevent blood clotting so that the destroyed helminths and their larvae do not clog the blood vessels. If the helminthiasis was severe enough, dogs are shown to drink a course of vitamins and minerals, including iron, to increase hemoglobin levels.

However, there are times when medicines alone are no longer enough: if there are too many helminths, they can cause intestinal obstruction or block the airways. In these cases, only urgent surgery can save the dog.

Symptoms of the appearance of worms in dogs

The appearance of worms in dogs can be calculated by a number of external signs. So, for example, if you notice that the dog began to lose weight, but at the same time eats for two, you should be wary. With a large number of parasites in the body, the dog may also show signs of anemia: pale gums and a whitish inner eyelid. At the same time, the coat becomes dull and as if powdered with dust, the dog may show signs of anxiety due to the fact that it experiences constant itching in the anus, and it is rather difficult to scratch it. Sometimes she tries to scratch herself on the floor, for which she “rides on the priest”. In worm-affected puppies, the belly usually looks very swollen. most often this can be seen in small mongrels.

When infected with ascaris in dogs, a wet cough is periodically observed. There may also be other manifestations specific to this particular parasite, of which there are a great many.
