Toxocara canis is a parasite that can be found in the feces of infected dogs, and it's essential to treat and care for both dogs and humans infected with this parasite.

The primary treatment for dogs is administering anthelmintic medications, such as fenbendazole, to eliminate the parasite from their system.

In severe cases, dogs may require supportive care, including hospitalization and fluid therapy, to manage symptoms like vomiting and diarrhea.

For humans, prevention is key, and this can be achieved by avoiding contact with contaminated feces and practicing good hygiene.

Causes and Prevention

Toxocara canis is a parasite that can be prevented through good hygiene and responsible dog ownership.

The parasite is commonly found in dogs that have not been properly dewormed, especially puppies.

Keep your yard clean by picking up your dog's feces regularly, as this can prevent the parasite from spreading to other animals.

Regular deworming of your dog can also prevent the parasite from taking hold.

Distribution In Dogs

Dogs of all ages can be infected with roundworms, but puppies are more susceptible due to their underdeveloped immune systems.

Almost all dogs will have roundworms at some point in their lives, with most infections occurring in puppyhood.

Roundworms are extremely common parasites in dogs, and nearly 100% of puppies and lactating bitches are infected with adult roundworms.

The prevalence of roundworm infection varies by region, with 70% of pups in Sydney, Australia infected, and 14.5% throughout the USA.

In the USA, the prevalence of roundworm infection is higher in the southeastern states, with 17.7% of dogs infected, compared to 11% in the western states.

Dogs that are not treated regularly are more likely to have roundworms, which can be passed on to their puppies.

Here's a breakdown of the prevalence of roundworm infection in different groups of dogs:

Roundworm Prevention

Your vet can provide a quality dewormer that will safely and effectively get rid of the worms. This is a great option if your dog is already infected with roundworms.

Monthly heartworm medication can also include ingredients to prevent and control roundworms on a continuing basis. This is a convenient way to keep your dog protected.

It's essential to consult with your vet for expert information on roundworms and any concerns you may have. They can help you determine the best course of action for your dog's specific needs.

By following these prevention methods, you can help keep your dog safe from roundworms and ensure their overall health and well-being.

Can Humans Get Roundworms from Dogs?

It's a good idea to pick up after your dog right away in yards and outdoor areas to reduce the risk of roundworm transmission to humans.

The eggs of canine roundworms can be ingested by humans if they accidentally eat contaminated dirt, and this can cause significant health problems.

In humans, the eggs can turn into larvae that become encysted in various organs of the body, which can sometimes cause serious disease.

It's essential to keep children from playing on ground known to be contaminated with dog feces, and to wash their hands frequently if they're playing outdoors where dogs may have been.

Dog stools in yards, parks, playgrounds, and other outdoor areas should be picked up and removed right away to prevent the risk of transmission to humans.

Symptoms and Diagnosis

Your veterinarian can check for the presence of roundworm eggs in a fecal sample from your puppy or dog on a prepared slide under a microscope.

A fecal exam is typically part of a puppy's first vet visit, and it's a crucial step in diagnosing a roundworm infestation.

If a roundworm infestation is light, the fecal sample may not include any eggs. This is because roundworms are extremely common in puppies, so experts recommend treating them routinely every few weeks.

Assuming the presence of roundworms in young puppies is a good idea, as they are very common and can be difficult to detect through a fecal exam.

Treatment and Care

Chemotherapy is the standard treatment for patients with liver, lung, or eye involvement due to toxocariasis. This treatment approach is effective in most cases.

For patients with lung involvement, hospitalization may be necessary to manage acute symptoms such as dyspnea and chest tightness. This ensures timely and proper treatment.

Treatment typically includes medications like mebendazole, thiabendazole, corticosteroids, and specific organ treatment. The prognosis of toxocariasis is generally favorable.

In some cases, ocular involvement may require ocular surgery. Hospitalization may also be needed for patients with liver or ocular involvement for diagnostic and/or therapeutic procedures.

Medical Care

Chemotherapy is often the treatment of choice for patients with liver, lung, or eye involvement due to toxocariasis.

For patients with ocular involvement, surgery may be necessary in some cases.

Hospitalization is sometimes required for patients with liver or ocular involvement, especially if diagnostic or therapeutic procedures like biopsy or laser surgery are needed.

In cases of lung involvement, hospitalization may be necessary to manage acute symptoms like dyspnea and chest tightness.

Antihelmintic therapy, such as mebendazole and thiabendazole, is a key part of treatment, often combined with corticosteroids and specific organ treatment.

The prognosis for toxocariasis is generally favorable, especially with prompt and effective treatment.
