Nematodes (roundworms)

Nematodes are the most extensive group of helminthiases. Various types of nematodes parasitize almost all organs and tissues of the animal.

A large number of nematodes can cause a lump of worms to form in the puppy's intestines, cause blockage and death of the pet. Pneumonia is also possible as a result of the migration of larvae through the lungs.

The diagnosis is based on the detection of parasite eggs in the stool. Whole parasites or segments of them are sometimes excreted in the feces.

Prevention of infection with worms is mandatory for female dogs before mating, since the larvae of some round worms can be transmitted to puppies even in the womb. It is especially difficult to cure babies from nematodes (toxocar and toxascaris). A dog infected with worms will produce less robust and active puppies than a healthy one.

Cestodes (tapeworms)

Cestodes are a type of helminth that most often parasitizes in the intestines of dogs. All cestodoses develop with the participation of one or more intermediate hosts.

It is usually not possible to determine that a dog is infected with cestodes by external signs. With a strong infection in the feces of the animal, segments of parasites of various lengths are noticeable. The coat of an infected animal is disheveled and dull, the dog is constantly thirsty and indifferent to food.

Worms in a dog. The disease is diagnosed when eggs and cestode segments are found in the dog's feces. Depending on the habitat of parasitic worms in the body of the dog, they are also subdivided into: intestinal; hepatic; pulmonary; heart.

Each of the above types of worms causes a certain worm disease in the dog, with characteristic symptoms and the ability to become chronic, leading to exhaustion of the dog. It must be borne in mind that nematodes and whipworms can easily infect humans.

Ways of infecting a dog with worms

Basically, helminths enter the animal's body in several ways. Infection of the puppy from the mother - occurs when the fetus passes through the birth canal. This is possible only if the mother herself suffers from helminthic invasion.

Contact with sick animals is considered the main source of transmission of worms. Therefore, it is undesirable to walk your pet without a collar and allow you to approach the yard dogs.

Infection occurs through external sources: water; the soil; dog feces; rivers; puddles. With close interaction of a pet with these sources, parasite damage can develop.

And also the carriers of some forms of worms are blood-sucking - fleas, ticks. For prevention, you should use special protective equipment, wash your dog regularly, visit a veterinarian.

What is the danger of worms in a dog

The danger is different. In some cases, these pests may not cause discomfort, or some kind of harm. On the other hand, they will be fatal.

Worms in a dog are different and each bring serious damage, or do no harm at all. To find out if your dog has worms, get tested. This is exactly how helminthiasis is determined. Regular examination and taking special medications makes it possible to avoid illness.

But in some cases it is not possible to regularly show the animal to a specialist. But you can give special drugs against pests, ask a specialist or in a ZOO store. Veterinarians recommend Drontal Plus. This is an excellent disease prevention. Give by prescription.

Many worms are dangerous because they cause mechanical harm to the internal organs. They attach to the intestines, heart, liver. They suck out useful substances. The internal organs are pierced. As a result, wounds appear that fester and get serious inflammation.

In addition, worms in dogs are dangerous toxins that they release. They feed, and then, in the usual way, all the food leaves the body of the worm, thus chemicals appear in the dog's tissues that lead to toxicity. Vomiting begins.

The danger also lies in their number. If a large number of worms are formed, thereby they clog the permeability of the intestines, esophagus. They can simply go out and block the airways. In all cases, a lethal outcome is possible if you do not provide assistance at a certain moment.

Signs of worms in dogs

In some cases, if a dog has a helminthic invasion for a long time, no symptoms occur. Therefore, for the timely detection of parasitic worms in a dog, you need to regularly take your dog for a routine examination to a veterinary clinic.

Worms in a dog. Typical signs of worms in dogs are:

  • disturbances in the work of the gastrointestinal tract: the dog has a changeable appetite (periodic lack of appetite, or increased appetite), against the background of a decrease in body weight;
  • the dog's taste preferences for food are perverted; begins to eat inedible items. Periodic disturbances of digestion and intestinal motility occur, which is manifested by frequent spasms, vomiting, diarrhea or constipation;
  • upon close examination of the feces, we find mucus, blood, eggs, larvae or the parasites themselves in it. We register severe itching in the anal area. The dog tries to get rid of itching by means of characteristic movements ("rides" on the back of the body);
  • upon external examination, the owners note that the dog has a swollen and hard belly against the background of protruding ribs. After eating, the dog has hiccups, food intake is difficult;
  • on examination, the dog is sluggish, inactive, symptoms of general anemia. The coat is dull and tousled, the dog has a tendency to develop dermatitis, eczema, dandruff;
  • the dog is characterized by growth retardation and development, the appearance of rickets.

If your dog shows at least one of the above signs, you need to visit a veterinary clinic with your pet. Sometimes your dog may look perfectly healthy on the outside, but this does not mean that your dog does not have worms.

Symptoms of a dog getting worms

How do you know if a dog has worms on its own? This question is of interest to many who have a pet and care about its health. Because some forms of parasites spread rapidly, affecting vital organs.

If dogs have pulmonary worms, symptoms such as: shortness of breath; frequent cough; sneezing; deterioration of health; violation of respiratory function.

Worms in the dog are characterized by symptoms. They, according to the degree of damage, types of parasites, their localization, can be pronounced, weak.

Even with the naked eye, traces of blood, adult parasites or worms, and characteristic mucus can be seen in the stool of a pet. Tapeworms in dogs are much more likely to cause constipation, as they are large and can block the intestinal lumen.

Often, the signs of helminths in dogs have a complex manifestation:

  • depletion of the body, lack of mood, impaired activity;
  • the appearance of malfunctions in the gastrointestinal tract;
  • weight loss, poor development, stunted growth; lack of appetite;
  • the external condition of the coat deteriorates markedly, becomes dull, and may fall out;
  • pallor of the mucous membranes; frequent constipation, diarrhea, vomiting

Round worms in a dog

Toxocara worms in dogs

Toxocara canis: a whitish worm up to 15 cm long, strongly pointed at the ends. Living parasites found in feces are coiled into a tight spring or flat spiral. If the parasites are small, owners often think the dog has swallowed the strings. Toxocara females are incredibly fertile - about 200,000 eggs per day!

Dogs become infected in utero, through breast milk, or through contact with an infected surface. Toxocar eggs remain active for up to a year, without fear of the sun and cold! After swallowing, the eggs quickly turn into larvae, literally gnawing through the intestinal wall. From there, they travel to the liver and then to the lungs.

These roundworms in dogs cause severe respiratory symptoms - cough, shortness of breath, etc. From the lungs, some of the larvae with blood flow into the tissues of organs and are inactivated.

Others are coughed up, swallowed, and end up in the intestines, where they develop into adults. Reproduction takes place in the intestinal tract - eggs are constantly released into the external environment. A similar species, toxascaris leonna, also lives in the intestines, but the larvae develop in the stomach without migrating. Therefore, they cause much less harm.

Hookworm worms in dogs

Ancylostoma caninum: small yellowish nematode up to 2 cm long, the head end of the worm is rounded. The oral apparatus is huge in comparison with the general size, consists of several rows of sharp teeth, shaped like a hook. The worm digs into the intestinal wall, swallows fragments of the mucous membrane and drinks blood, provoking anemia, spasms, and inflammatory processes.

Distributed everywhere. Infection through the skin is possible - the larvae migrate to the bronchi and lungs, molt several times, cough up and enter the intestines. While the worms are in the dog's lungs, obvious breathing problems (shortness of breath, wheezing, coughing, etc.) appear. Death is possible without treatment, especially when it comes to a puppy or a young dog.

Uncinaria worms in dogs

Uncinaria stenocephala: small worms up to 2 cm in length, extremely prolific and voracious. Distributed everywhere. The oral apparatus consists of a pair of sharp crescent-shaped plates.

It is difficult for owners to understand what these worms look like in dogs. adult live parasites are rarely excreted in the feces. But there are plenty of eggs in the feces - the diagnosis will be clear after the first analysis.

If you suspect, it is important to examine the pet as soon as possible - in an acute form, the disease can kill a dog in a month!

Like hookworms, uncinaria significantly traumatize the intestines, which leads to anemia and digestive disorders up to incessant bloody diarrhea. In humans, these worms are harmless (sometimes they penetrate the skin, causing itching and hives, but quickly die due to inappropriate temperature).

Dirofilaria worms in dogs

Dirofilaria: Typical whitish nematodes, tapered at the ends. Females are larger, up to 15 cm. Males are three times smaller. Microfilariae (larvae) are tiny, with a rounded front end. Infection occurs through a mosquito bite.

Dirofilaria - heart worms, in dogs, symptoms characteristic of cardiovascular ailments (tachycardia, fatigue, insufficiency, tearful cough, etc.) are often observed.

The larvae circulate in the bloodstream, causing harm to the entire body.

Localized in the heart, adults literally clog the internal space, which leads to death without treatment. For people, dirofilariae are not so dangerous - they live under the skin and cannot reproduce.

Ascaris - round worms in a dog

Ascaris is a round parasitic worm that lives in the small intestine of dogs. An adult grows up to 20 cm in length and feeds on the food masses of its host. The body of the parasite is covered with a flexible cuticle, which keeps it from the effects of intestinal juice and digestive enzymes.

The disease caused by ascaris in dogs is called toxocariasis (ascariasis). Most often puppies suffer from it. Living in the small intestine of a four-legged friend, the worms form dense lumps, causing obstruction of this organ. As a result, the intestinal walls rupture and the inevitable death of the pet.

Roundworms do not bring serious inconvenience to adult dogs, but only slowly destroy their organisms from the inside. The motto of the roundworm living in the body of an adult dog is: “Eat, but do not kill your master. Multiply and pass on your offspring to another."

Roundworms multiply rapidly. An adult female lays 200,000 eggs per day. All of them come out with feces, they can get on the dog's coat. Ascaris eggs develop in the soil and enter the body of a new host through food and objects on the ground.

Flat worms in a dog

Cucumber tapeworm in dogs

Dipilidium caninum: A typical tapeworm, consisting of separate segments. In a large dog, it can develop up to one and a half meters in length! Mature segments come out with feces, dry out and burst.

In order for the larvae to become dangerous to mammals, they must first enter the flea's body (blood-sucking insects accidentally swallow eggs). Ripe larvae enter the dog's stomach when it accidentally swallows a flea.

These tapeworms in dogs cause severe symptoms - intestinal inflammation, intoxication, diarrhea, loss of appetite, etc. Worms damage the intestines and can clog the lumen, leading to obstruction.

Echinococcus in dogs

Echinococcus: small parasites up to 0.5 cm. Larvae and eggs are microscopic - cannot be detected in feces with the naked eye. Cutting oral apparatus - up to 30 sharpest hooks! They are very damaging to the intestines, a young dog or puppy can die in a few weeks.

The cattle swallow the larvae, eating grass contaminated by herding and stray dogs. Worms circulate in the blood of cattle until they form a "capsule" - a small slowly growing ball with parasites inside. Dogs become infected by eating raw meat (lamb, beef, pork).

Wide tapeworm in dogs

Diphyllobothrium latum: huge tapeworms up to 10 meters in length, even small individuals consist of hundreds of "segments"! A dog becomes infected by eating raw fish. Like all tapeworms, this worm injures the intestines and releases toxic substances that poison the dog's body. Without treatment, anemia, exhaustion, and gastrointestinal disorders rapidly increase.

Fluke worms in dogs

Opisthorchida: small fluke less than a cm long, with two suckers - oral and peritoneal. Localized in the gallbladder, bile ducts, liver, pancreas. As is the case with heart worms in dogs, liver flukes cannot be seen in feces.

Dogs become infected by eating raw river fish. The fish swallows the larvae, feeding on molluscs. And the larvae enter the snails when the water is polluted with feces - such a vicious circle.

The suckers are extremely dangerous! They destroy the affected organ, impairing its function. Treatment is long, with specific drugs (conventional anthelmintics are ineffective).

Even an experienced parasitologist is unlikely to be able to tell everything about what kind of worms there are in dogs - too many types of worms attack pets. Therefore, it is more important for the owner to remember about prevention and contact the veterinarian in a timely manner if any symptoms of discomfort are noticeable. Remember that modern drugs for worms are not dangerous in recommended doses.

Prevention of worms in a dog

Before starting the tying of the cable and the bitch, both animals are given an anthelmintic. After the bitch gives birth, before giving the nipples to the puppies, treat them with an anti-mucous impregnation or simply wash them with soap and water and then you can regale the puppies.

When the puppies are 14 days old, you can start prophylactic worm control. Adult dogs should take anthelmintic medications several times a year. Below we will consider how much and how to take.

Watch out for pets. Try not to let any waste be picked up from the ground. Dogs should not eat the feces of other dogs. To exclude contact with stray dogs. There should always be clean water in the bowl, and also stuff only from clean dishes.

If you are feeding and are too lazy to clean the dog's bowl, then be aware that flies will lay eggs in the food left. If a dog eats a bite it likes, it will become infected with helminths.
