Roundworm Identifying Dog Worms: Common Types and Symptoms

Dogs can get infected with roundworms, which can be identified by their physical characteristics and symptoms.

Toxocara canis is one of the most common types of roundworms found in dogs. They are white, long, and thin.

Roundworms can grow up to 12 inches in length, making them easy to spot in a dog's stool or vomit. Their presence can cause a range of symptoms, including diarrhea, vomiting, and weight loss.

Dogs can become infected with roundworms through contact with contaminated feces or by eating infected animals.

There are several types of worms commonly found in dogs, including roundworms, hookworms, tapeworms, and whipworms. These worms are all gastrointestinal parasites, meaning they live in the intestinal tracts of dogs.

Roundworms are one of the most common intestinal parasites in dogs, especially puppies. Dogs can be infected with roundworms by eating small mammals that are already infected with larva, ingesting eggs directly from the environment, or from their mothers when they are nursing.

Here are the main types of dog worms:

Some types of tapeworms, like Dipylidium caninum, can be acquired from eating fleas, while others, like Taenia species, use other mammals as intermediate hosts in their life cycle.

Roundworms are one of the most common intestinal parasites in dogs, especially puppies. They can be found in the intestines of puppies as early as 1 week after birth.

Toxocara canis is the most important species of roundworm, and its larvae can migrate in people, making it a zoonotic infection. Infections with Toxocara canis usually occur by transfer into the developing fetus through the placenta.

Young pups may also be infected while nursing, and if they eat the eggs that have been in the environment for at least 4 weeks, the eggs hatch, releasing larvae that penetrate the intestinal wall. The larvae migrate through the liver, reach the lungs via the bloodstream, and mature to egg-producing adults in the small intestine.

Many dogs with roundworms show no signs of the infection, but if they do, the common signs are a bloated belly, poor weight gain, diarrhea, and/or vomiting with worms visible in the vomit. These symptoms can be associated with coughing and pneumonia in the early stages.

Infection in dogs and cats is diagnosed by detection of the roundworm eggs in feces using a microscope. Treatment for roundworm infections in dogs includes certain preventive programs for heartworm infection that also control intestinal roundworm infections.

Transmission of infection from mother to newborn can be greatly reduced by a program of antiparasitic drugs given during pregnancy and after the birth of a litter. Pups should be treated as early as possible, ideally 2 weeks after birth and repeated at 2- to 3-week intervals to 2 months of age, then monthly to 6 months of age.

Tapeworms are segmented worms found in the intestines of dogs. They rarely cause serious disease.

Several types of tapeworms can infect dogs, depending on their lifestyle and environment. Urban dogs are more likely to get Dipylidium caninum, a common tapeworm of dogs and cats, from eating fleas.

Suburban, rural, and hunting dogs have more access to small mammals and raw meat, increasing their risk of exposure to other tapeworm species like Taenia and Echinococcus granulosus.

Signs of tapeworm infection can be subtle, ranging from a failure to digest food normally to colic and mild diarrhea. In rare cases, more severe symptoms like telescoping of the intestine and seizures can occur.

Flea control is a critical step in preventing tapeworm infections, even for indoor dogs. This is because Dipylidium caninum can cycle through fleas, allowing them to infect dogs.

Preventing dogs from eating dead or prey animals can also limit their exposure to other tapeworm species. An accurate diagnosis is essential for determining the best course of treatment and prevention.

Whipworms are another intestinal parasite of dogs that can cause a lot of inflammation in the large intestine or colon.

The eggs of whipworms are shed directly into the environment and can be ingested by other dogs, leading to symptoms like diarrhea, straining to poop, weight loss, decreased appetite, and/or anemia.

Whipworms have no intermediate hosts, which means they don't need another animal to complete their life cycle before infecting dogs.

It's essential to clean up thoroughly after your dog (or other dogs) poop and to make sure dogs are not housed in moist environments where the eggs can survive.

To diagnose roundworms in dogs, your vet will use a combination of physical exams and diagnostic tests. A physical exam can reveal signs of a parasite infection, such as a distended belly or abnormal heart and lung sounds.

A fecal exam is often recommended for dogs showing signs consistent with intestinal parasites. You'll need to bring a fresh poop sample to your vet, who will process it to look for eggs that are shed in the stool. Different parasite eggs look distinct, making diagnosis easy if eggs are present.

Some dogs may not show symptoms until the infection is severe, but common signs include diarrhea, gas and bloating, vomiting, and weight loss. Heartworms, on the other hand, mainly live in blood vessels in the heart and lungs, and may not cause obvious symptoms until the infection is severe, at which point signs may include coughing, shortness of breath, or even death.

Here are some common signs of roundworms in dogs:

A blood test is the main way to test for heartworm disease in dogs, and may be performed as part of a routine annual check-up. If the test comes back positive, additional tests are performed to confirm the diagnosis.

Your veterinarian will use a combination of physical exams and diagnostic tests to determine if your dog has worms. A thorough physical exam is the first tool your vet will use to look for signs of a parasite infection.

During the physical exam, your vet will examine your pup from head to toe, listen to their heart and lungs, and feel for any abnormalities on their body. They may notice a distended belly, gas-filled intestines, tapeworm segments around the anus, or abnormal heart and lung sounds.

A fecal exam is often recommended for dogs showing signs consistent with intestinal parasites. To perform this test, you'll need to bring a fresh poop sample to your vet. There are different tests that can be performed to check for parasites, and the most common one is called a fecal flotation.

In a fecal flotation test, the poop sample is processed to look for eggs that are shed in the poop. Different parasite eggs look very distinct, so if the eggs are present, the diagnosis is easy. However, due to different life cycles of these worms, eggs are not always present in a single poop sample, even if the dog has parasites.

Blood tests are the main way to test for heartworm disease in dogs. An in-house antigen SNAP test is usually part of a routine annual check up, and may be performed more frequently if warranted. This is a basic screening test, and if it comes back positive, additional tests are performed to confirm the diagnosis.

Here are some common diagnostic tests used to identify worms in dogs:

Keep in mind that multiple tests may be necessary to confirm a diagnosis, and it's possible to have a false negative result. If your dog's symptoms persist, it may be worthwhile to submit additional samples.

Some worms in dogs can be contagious to humans. Hookworms, tapeworms, and roundworms can all be transmitted to people.

Infestation is not always serious, but it can cause problems, especially for small children and people with compromised immune systems.

Some people are more susceptible to worm infestations than others. This includes small children and people with compromised immune systems.

Hookworms can be particularly problematic for people with weakened immune systems. They can cause anemia and other serious health issues.

If your dog is diagnosed with roundworms, the good news is that they can be easily treated with the right dewormer. Most dewormers are medications that can be given by mouth, and there are specific drugs that target different parasites.

To get rid of worms in dogs, you'll need to consult your veterinarian about the medication that will be most effective for your dog. They may prescribe a combination of treatments or a deworming medication that targets all types of worms.

Some common drugs approved for treatment of intestinal parasites in dogs include Fenbendazole, Milbemycin, Moxidectin, and Praziquantel.

To prevent worms in dogs, good hygiene is crucial. Picking up after your dog and preventing them from consuming or sniffing the poop of other dogs will reduce the risk of your dog contracting worms.

You can also use heartworm preventatives and flea and tick preventatives that include active ingredients that can help prevent common intestinal parasites.

Here are some common dewormers used to treat hookworms, roundworms, whipworms, and tapeworms:

Remember to always follow your veterinarian's instructions when administering oral dewormers, as they are strong medications.
