How to tell if a puppy has worms

The clinical picture of pulmonary helminthiasis

The appearance of worms in the lungs of a dog is very rare and is caused by a special type of parasite. krenosomas. Helminths are transmitted through intermediate hosts. terrestrial molluscs, mice, birds, reptiles. Infection occurs if the dog eats any of the representatives of these groups containing krenosis larvae. Since the likelihood that a pet will feed on shellfish, birds, mice or reptiles is extremely low, crenosomiasis is practically not found in dogs.

But in case of infection, the disease manifests itself as signs of lesions of the bronchopulmonary system:

  • sneezing;
  • runny nose;
  • prolonged cough, worse at night.

Blockage of small bronchi with worms can lead to the development of focal pneumonia. A sick dog is exhausted, rapidly losing weight, the quality of its coat deteriorates.

Intestinal worms are among the most common

Based on the places of concentration, all helminths are divided into the following groups:

In puppies, intestinal parasites or toxacar are most often found. Having swallowed the egg of this helminth, the animal becomes its owner. A larva emerges from the egg in the intestine, which enters the circulatory system and migrates through its vessels to the lungs. From there, it is thrown into the mouth with a cough, and swallowed, it again enters the intestines. After that, the parasite attaches to the mucous membrane of the organ and remains in it, growing into a sexually mature individual.

The most difficult infection with this type of helminths is carried by small puppies. They can refuse food, which leads to stunted growth and development. Therefore, having found such worms in a puppy, you urgently need to contact a veterinarian and start treatment.

The choice of anthelmintic drugs

Anthelmintics are divided according to the principle of action into 2 types:

  • preventing worms from feeding;
  • paralyzing their neuromuscular system.

Having found worms in a dog, treatment should be started immediately. If it is not possible to immediately contact a veterinarian, you can independently give the animal the drugs recommended for the prevention of helminthic invasions. Without professional diagnostics, it is better to use universal broad Spectra products, among which the most effective are:

  • “Milbemax”. affects the larvae and sexually mature helminths of all types;
  • “Drontal plus”. destroys only intestinal worms, but is not effective against larvae.

Since parasites quickly get used to drugs, especially if used incorrectly, it is recommended to use different drugs each time, alternating them not by name, but by the principle of action.

Signs of worms (helminths) in a dog

It is quite difficult to understand whether a dog has worms: they may, in principle, not manifest themselves in any way for a long time. Some symptoms of helminthiasis are often confused with other diseases altogether. And this often interferes with the diagnosis and treatment of worms in pets.

Thus, it is best to visit a veterinarian several times a year to prevent worms in dogs. However, the ability to determine the presence of helminthiasis in your four-legged friend is also independently, you just need to remember about the main signs.

The most obvious symptoms of infection are as follows:

  • the dog began to eat very little, or stopped altogether;
  • the opposite option is also possible: the pet eats everything (even inedible items), but still significantly loses weight;
  • frequent digestive upset: vomiting, diarrhea, or constipation;
  • general lethargy, decreased physical activity;
  • dull look, not smoothed coat;
  • in the dog’s feces there is blood, worms, their eggs;
  • very severe itching: you can understand this when the pet starts to “crawl” the booty on the floor;
  • the belly is swollen, and the ribs protrude;
  • the development of the animal is inhibited in general.

It can be not only helminthiasis, as often the symptoms are similar in some diseases. Unfortunately, dogs cannot speak, and we can only observe their general condition, and therefore how to understand that a dog has worms is a difficult question.

How to treat

How to remove worms and what means can be used for this? Treatment should be started immediately after the diagnosis has been clarified. Before worming a dog, you must carefully read the instructions and strictly adhere to the recommended dosage. Decreasing the indicated dose will lead to incomplete cure, and an increase can cause serious poisoning.

If it is necessary to drive out parasites in puppies up to 3-4 months old, it is better to choose funds in the form of suspensions. A single dose is calculated depending on the weight.

For puppies from worms, the following drugs are used:

  • Drontal Junior. The remedy is recommended from two weeks of age. Completely eliminates nematodes, but less effective in relation to other types of helminths.
  • Prazicide. The drug can be used to treat dogs from three weeks of age. It is produced in the form of suspensions with different concentrations of the active substance. Prazicide is active against round and tapeworms.
  • Prazitel. A suspension is prescribed from two weeks of age with nematodosis, cestodosis, trematodosis and mixed type helminthic invasion.

How to tell if a puppy has worms

Taking a four-legged baby into the house, you will have to not only feed and raise him, but also monitor his health. And often it is this moment that makes you refuse to have a pet in the family. But if you are ready to take risks, and still decide to buy a puppy, then he will give you a lot of pleasant moments. However, you will have to monitor his health, as walking down the street he can be attacked by parasites. And some of the most common and dangerous are worms. The fight with them should be carried out constantly, throughout the life of your four-footed pet. Read about how to make it as effective as possible and how to worm puppies in this article.

Symptoms of worms in puppies

It is unlikely that you will find at least one dog that would not have suffered helminthiasis. And if parasites are less dangerous for an adult animal, then they can do quite a lot of harm to the health of babies.

The main signs of worms in a puppy are, first of all, developmental delay and a wobbly gait. And pet owners should understand that the manifestation of such symptoms is a sure sign of infection with helminthiasis. And you urgently need to contact the veterinarian.

You can also find out that the puppy has worms by symptoms such as:

  • Digestive problems leading to poor bowel movements
  • Frequent infectious diseases
  • Weight loss with increasing appetite
  • Pallor of mucous membranes
  • The appearance of mucus and parasites in the stool
  • Development of dermatitis
  • Bloating.

But being the owner of a four-footed baby is not worth the manifestation of obvious symptoms of infection.

Veterinarians recommend first worming a puppy at the age of 1.5 months. And then repeat this procedure regularly, preferably once every 3 months.

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

Pulmonary worms in dogs

Helminths in the body of a person or animal behave as they want: they look for the most pleasant place to live and firmly settle there. Some worms target the lungs and the food system.

The main symptoms in this case are coughing, vomiting, sudden weight loss, and the development of pneumonia. Even with these signs, you cannot diagnose yourself: it may turn out to be a completely different disease.

These worms are often referred to as esophageal. they are not heartworms in dogs. Upon closer examination, it turns out that they are red and love to curl up in a spiral. Helminths affect arteries, and when they get to the esophagus and other organs, they begin to gather in balls, in which some researchers count up to 25 individuals up to 10 cm in size.

How to tell if a dog has worms: important details that will warn you about the disease

If you are one of the owners who carry out the prevention of worms in their pet from time to time, this article will be useful to you. We assure you that if you worm your pet more than six months ago, make sure and understand that the dog will have no problem with worms. Timely prevention will protect your pet’s health, this is not a trick or manipulation, but a proven fact.

Particular attention should be paid to dog owners who do not actually walk on the street. they go to the toilet on the tray and almost always sit on their hands. Your pets are under the same threat as the dogs running around the common areas. over, you can also be source of infection for a quadruple.!

Ways and methods of infection

Modern veterinary medicine and the zoological industry have reached unprecedented heights, but neither one can convince animal owners to take prevention seriously. We are talking about vaccinations, prevention of helminths and blood-sucking parasites. The vast majority of owners chase fleas to dogs, because they can be seen. Worms are often forgotten, but this happens only because the owner overlooks the obvious signs of invasion.

Note! Worm infestation can be judged by the appearance of the dog: faded coat, poor skin and claws.

It is impossible to protect yourself from worms 100%. Take it for the fact that the dog has worms, and you do. Do not panic or try to deceive nature, the goal of prevention is to prevent the proliferation of parasites. The life cycle of most worms can be broken down into periods of 3-5 months. That is, the parasites live for 3 months in a measured way, and after that, the peak invasion occurs. It is for this reason that I recommend that dogs be treated once every 3 months. Some types of worms multiply constantly, without peaks and troughs, there are worms that cannot be overcome with conventional drugs. you need to know these nuances.

Helminths are a large family divided into species. Nature is arranged in such a way that the most common worms are easy to eliminate, and the rare ones, which are difficult to get infected, are not always cured by traditional methods. Absolutely any environment is inseminated with parasite eggs, but this does not mean that infection will occur immediately after contact. Almost all but the most common types of worms have to go through certain stages of maturation in order to parasitize on dogs or humans. Especially dangerous worms that develop using multiple hosts.

Note! Some parasite eggs can be airborne.

Infection with worms does not pose a threat as long as the parasites have not multiplied to an impressive number. The more worms, the more painful the condition of the dog. This happens because helminths feed on blood, lymph, tissues and nutrients in the intestines. Even when infected with primitive roundworms, the animal quickly develops vitamin deficiency and weight loss.

Another negative factor of infection with worms is intoxication. In the process of their vital activity, the worms secrete waste products, and when the invasion reaches a critical level, some of the parasites die. Waste worms and their decaying remains are a constant source of toxins that “hit” the liver, kidneys and health of the pet in general.

Note! Long-term invasion without owner intervention can lead to intestinal blockage.

An adult dog can fight parasites for a long time, but if the worms actively multiply in the body of a young dog, everything can end tragically. The intestinal wall of a puppy is thinner and not as strong as that of an adult dog. When infected with worms that multiply rapidly, the intestines can simply rupture. In addition, young animals are hard to tolerate intoxication, they refuse to eat, stunted and quickly weaken.

Important! Dogs and humans have a lot of common types of worms, that is, a pet can infect you, and you can infect him.

Common signs

Even an inexperienced owner can identify common symptoms of infection. The problem is that the development of the clinical picture and the degree of its threat to the life of the pet is very different depending on the type of parasite. It is a mistake to believe that worms live only in the intestines of a dog. There are varieties that parasitize the respiratory system, brain, heart, kidneys, liver, pancreas, muscles, eyes, etc.

The highest risk of infection falls on the most common types of worms and they belong to the intestinal. The main localization of parasites is in the small intestine, and if there are too many worms, then the large intestine.

Do not forget that the toxins released by worms destroy the intestinal microflora. Even these general data make it clear that the condition of an infected dog is significantly worsening. Symptoms include:

  • Weakness, apathy, rapid fatigue, chills at a comfortable ambient temperature.
  • Vomiting, nausea, diarrhea, false diarrhea, constipation.
  • Blood in the stool.
  • White fragments of worms with clots of mucus in the stool.
  • Itching in the genital area, attempts by the dog to scratch the anus on the ground or floors.
  • Slightly but constantly increased or decreased body temperature.
  • Thick discharge from eyes and nose, color is usually light.
  • Lack of shine and elasticity of the coat.
  • Hair loss, severe itching, unnatural gray hair, severe loss of whisker pigmentation.
  • Putrid or foul breath odor.
  • White, blue, yellowish, or inflamed mucous membranes.
  • Sneezing and coughing with no symptoms of respiratory infections.
  • Distortion of normal appetite. the dog eats a lot or little, while losing weight.
  • Low hemoglobin, metallic saliva odor, low extremity temperature (iron deficiency anemia).
  • Seizures or severe tremor is a sign of severe intoxication.

Note! Infestation in a puppy can be identified by a swollen belly or a so-called pear-shaped figure.

As you can imagine, the presence of symptoms and the degree of their intensity depends on the number of parasites and the state of health of the dog. A young, active pet will stay healthy for longer than a puppy or an older dog. The lifestyle is also important, with frequent walking outside the city, the pet has more chances to pick up parasites at the same time, the dogs themselves find and eat herbs containing substances poisonous for worms. Quadrupeds are at greatest risk, picking up food leftovers from the ground or walking on their own. It should be understood that infection with worms in this case is only part of the possible consequences. Poisoning, injuries received in fights and under the wheels of cars are much more serious than infection with worms.

The above symptoms are very extensive, they can indicate both an infestation by worms and the development of another ailment. If your dog starts to lose weight, it is advisable not to experiment and see a doctor. The presence of worms is confirmed only by analyzes, and they do not always give the correct result the first time. If your dog is sick, and you stubbornly poison the worms, you are much more likely to harm than help.

Important! Do not allow your pet to be treated by eye, ask your veterinarian for tests and confirm your diagnosis. At the same time, the recommendation for prophylaxis will be reasonable if the dog has not been worms for more than 3-4 months.

Varieties of worms in dogs

Helminths can be similar to each other. One of the most effective ways to identify the type of worms that are parasitic in the dog’s body is to know the environmental and situational factors that are most favorable for each type of worm.

tell, puppy, worms

Canine toxocara (roundworm) can be transmitted to puppies even at the stage of intrauterine development, since eggs and larvae are able to penetrate the placenta. Also, infection is possible through breast milk. Adult animals become infected by eating meat of intermediate hosts. sheep, pigs, birds, rodents, which contain helminth larvae.

Cucumber tapeworm infects dogs if an infected flea containing worm eggs is accidentally ingested.

Dog whipworm eggs develop in moist soil, so animals run the risk of infection by running in wet grass.

The broad tapeworm, like the cucumber tapeworm, belongs to tapeworms. But unlike it, it reaches enormous sizes (up to 15 m) and is the longest worm that can live inside a dog. Infection occurs when eating infected fish.

In filarias, insects (mosquitoes, biting midges, horseflies, midges) act as intermediate hosts, so the dog can become infected after their bites. This superfamily also includes heartworms, as well as other dirofilariae, which most often live under the skin. The greatest danger is observed in the regions of distribution of such insects, which are vectors.

Echinococcus can be contracted in a dog by eating the meat of an infected animal (livestock).

Various types of trematodes are also found in dogs, in particular, liver flukes (cat fluke, Chinese fluke) Alaria alata, Japanese schistosome, etc. A dog can become infected with them by eating raw fish, tadpoles, drinking contaminated water.

The main types of worms that occur in dogs

Symptoms and Signs

Many of the symptoms of infection are general and non-specific. Thus, difficulties arise in diagnosing worms. First of all, you need to look for worms in the feces. Sometimes, even in the absence of symptoms, they can be detected in this way and at the same time, usually by accident.

Basically, the symptoms of helminthiasis are manifested in the form of gastrointestinal disorders. However, some types of parasites are able to migrate through the body, affecting other organs. As a rule, there is no symptomatology with a weak invasion. A large number of intestinal worms can irritate the mucous membrane, which is manifested by symptoms such as nausea, vomiting, diarrhea (sometimes mixed with mucus and / or blood), poor appetite and weight loss.

It is sometimes possible to suspect helminthiasis behind respiratory symptoms. cough, discharge from the eyes and nose. Certain roundworms and flukes clog the blood vessels, the heart, or the lungs (heartworms). This can cause coughing, heavy or rapid breathing, and lack of energy. Due to a bleeding disorder, some dogs start bleeding uncontrollably even after minor injuries. Sometimes such invasions are fatal.

You can pay attention to the physique of the dog. After all, worms, especially tapeworms, absorb nutrients from the animal’s body, which leads to dramatic weight loss.

Any of these signs require an immediate visit to your veterinarian. Although treatment can be expensive, it increases the chances of a good outcome.


If symptoms are present, a fecal specimen should be collected and taken to a veterinary clinic for fecal worm eggs to be tested. Independent detection of parasites is also possible, but at a certain stage of the life cycle, there are no adults in the feces, but their eggs are present, which cannot be seen with the naked eye.

To collect the sample, feces are taken with a disposable spoon and placed in a clean screw-on container with a tight-fitting lid. It can be kept refrigerated before it goes to the clinic for testing, but the sooner it gets to the lab, the better. Your veterinarian may ask you to collect stool samples from your dog once a day for 3 consecutive days in one collection. This may be necessary to avoid a “false negative” result. In the pooled sample, the risk of obtaining inaccurate data is reduced.

Sometimes the best diagnosis is to document the risk factors for the dog. The owner should write down the environment in which the animal lived, about its habits. You also need to determine the severity and duration of the symptoms of the disease, and then provide this information to the veterinarian.


Treatment of diseases with parasitic worms in dogs is carried out with anthelmintic drugs. The specific drug, as well as its dosage, is prescribed by the veterinarian and depends on many factors, from the age of the animal to the degree of invasion. They contain active substances such as pyrantel, piperazine, praziquantel, fenbendazole.

How to tell if your dog has worms?

There are many different types of helminths that can inhabit a dog’s body. But the greatest concern among them is some species of round and tapeworms, as they are the most common. It is impossible to determine which parasite a dog has based on symptoms alone. However, knowing the general signs, you can provide timely treatment for your pet.

How to identify the type of worms in a dog?

While many worms are difficult to distinguish among themselves, each of them has some distinctive characteristics that make it possible to identify the type of worm:

  • toxocara (dog roundworm) resemble boiled noodles, their body can reach 18 cm in length, smooth and round;
  • tapeworms (including various tapeworms) have a flat body, consisting of segments (length varies from 50 cm to 250 cm). in feces and vomit, not a whole worm is usually found, but part of it that carries out the eggs. These emerging segments (proglottids) resemble fly larvae and can remain active for some time;
  • whipworms are much smaller than tapeworms, their length is 0.5-2 cm, the body is thin, like a thread, translucent;
  • trematodes, which include hepatic, pulmonary and blood flukes, are flat organisms that resemble plant leaves. And schistosomes (blood flukes) are elongated and oval. But trematodes or their parts never leave the dog’s body with feces, since they parasitize mostly inside organs or vessels, and not inside the intestines. Infection with them occurs much less frequently than with round and tapeworms;
  • filariae (including heart and subcutaneous worms). threadlike light worms, the length of which reaches 30 cm.

Preventive measures include:

  • Timely detection and treatment of helminthiasis.
  • Prevention with anthelmintic drugs, especially in the case of living in a region with a high incidence rate.
  • Cleansing dogs from fleas.
  • Restricting an animal’s access to a hostile environment.
  • Keeping the animal from communicating with other dogs that have not been dewormed.
  • Limiting contact with wild and predatory animals.
  • Exclusion from the diet of raw fish, dubious meat.

You need to visit your veterinarian regularly. Keeping the dog under his control will keep the dog healthy. Your veterinarian will be able to identify problems before they become serious.


It is possible to detect parasites of this type in puppies by the presence in the feces of their eggs or segments that have come off the adult. Common diseases caused by tapeworms include:

  • Echinococcosis. Common in small dogs fed uncooked meat. The causative agent of the disease is echinococcus, which is localized in the liver and lungs, where it closes in a shell and forms a large seminal bladder.
  • Diphyllobothriasis. This disease is caused by the largest worms called wide tapeworms (5-6 meters).
  • Teniosis. It affects not only the intestines, but also the eyes, brain, lungs, liver.

One of the intermediate forms of tapeworms is cysticercus. This worm larva can enter any organs of the puppy with the blood stream and cause cysticercosis, which is difficult to treat.

be careful

According to statistics, more than 1 billion people are infected with parasites. You may not even suspect that you have become a victim of parasites.

It is easy to determine the presence of parasites in the body by one symptom. bad breath. Ask loved ones if your breath smells in the morning (before you brush your teeth). If so, there is a 99% chance that you are infected with parasites.

Infection with parasites leads to neuroses, rapid fatigue, sudden mood swings, and later on, more serious diseases begin.

In men, parasites cause: prostatitis, impotence, adenoma, cystitis, sand, kidney and bladder stones.

In women: pain and inflammation of the ovaries. Fibroma, fibroids, fibrocystic mastopathy, inflammation of the adrenal glands, bladder and kidneys develop. As well as heart and cancer diseases.

We want to warn you right away that you do not need to run to the pharmacy and buy expensive medicines, which, according to pharmacists, will exterminate all parasites. Most drugs are extremely ineffective, and they also cause tremendous harm to the body.

What to do? First, we advise you to read the article. This article reveals a method by which you can cleanse your body of parasites without harm to the body. Read the article

  • Toksokars. The female worms of this class can grow up to 15 cm. Sexually mature parasites are localized in the upper parts of the small intestine.
  • Uncinaria and hookworms. These helminths in puppies cause diseases of uncinariosis and ankylostomiasis. The worms are up to 15-16 mm in size and are similar in structure, both species have characteristic spines at the end. Parasitic worms in the small intestine.
  • Dirofilaria. Helminths look like long, whitish gray filaments up to 30 cm long. When infected with heartworm species, animals often die from vascular obstruction with tangles of worms. The skin form is easier.

Mass invasion by round worms in puppies is often complicated by rupture of the intestinal walls and the formation of foci of inflammation in the places where the larvae enter the tissue.

Traditional medicine

At home, you can get rid of worms only with the help of combination therapy. Folk recipes are used as an addition to pharmaceutical preparations. In combination with tablets and suspensions, you can give the puppy infusion of garlic or tansy to drink. Bitter wormwood and pumpkin seeds have a good anthelmintic effect. Decoctions are prepared from them and given to the animal on an empty stomach, a teaspoon per kg of weight. Worms should be poisoned for at least a week.

What do worms look like?

Determining which type of worm parasitizes a puppy is not easy. Adults rarely enter feces alive. Usually, in the analysis of feces, laboratory assistants find eggs or cysts of worms. The appearance and structure of helminths largely depends on localization. The largest individuals live in the intestines. Small and medium-sized ones live in dense tissues of internal organs. All types of parasites in puppies are divided into three groups.

Round worms

They are the causative agents of nematodes. They resemble a needle or spindle in shape. In the photo of worms of this type, the narrowing of the body in the tail and head is clearly visible. Round worms reproduce sexually.

Common types of nematodes include:

At what age do puppies develop helminths?

Parasitic infection can occur during any of the growth periods of a dog. Many babies become infected after 1 month of age when they start going out for walks. They are usually inquisitive and pick up various waste from the ground, which can be stained with feces with worm larvae.

But there are cases of detecting worms in newborn puppies, which were born just a couple of weeks ago. Here, the source of infection is usually the mother of the pet or other adult dogs and cats that bring the eggs of the parasites indoors on their fur.

A dog cannot infect a person with its worms, but it is often a carrier of parasitic larvae dangerous to humans.

How to remove worms from a puppy

Therapy of parasitic diseases in young pets should be carried out under the supervision of a veterinarian. Pharmacy preparations have a number of side effects, which are more often manifested in babies. When using drugs, you should carefully read the instructions and give the animal worm remedies strictly in the indicated dosages.

For the treatment of invasions, tablets, suspensions, drops and injections are used. For the treatment of worms, it is more convenient to use suspensions and tablets. Drops are used mainly with simultaneous infection with internal and external parasites. Injections should be given only in case of severe helminthiasis. The solutions are injected into the muscle, nape, or vein. The procedure must be performed by a specialist.


Worms of this type often affect small breed dogs and puppies. Parasites do not grow to large sizes, but when they multiply, they can cause a number of pathological symptoms. Flukes live in the intestines, lungs, liver, bile ducts, and pancreas. In small dogs, two types of trematodes are mainly parasitized: these are opisthorchis and alaria. They damage internal organs with their suckers, and their larvae can easily spread through the body with blood.
