What are intestinal worms in dogs?

Intestinal worms are parasites that live inside your dog’s digestive system. 

These worms can cause a range of health problems, from mild discomfort to serious illness, depending on the type and severity of the infestation. 

Protecting your dog from intestinal worms is a crucial part of pet care.

The most common intestinal worms in dogs

In Australia, the most common gastrointestinal worms found in dogs are roundworm, whipworm, tapeworm and hookworm. 

Roundworm

A common worm in puppies. It can cause bloating, ill thrift, diarrhea, weight loss, and vomiting. 

Hookworm

These tiny worms attach to the intestinal lining and feed on blood, leading to significant blood loss, diarrhea and lethargy. They are more common in Queensland than Victoria, however, it is still possible for dogs in Melbourne to contract hookworms.

Whipworm

Found in the large intestine, whipworms can cause chronic diarrhoea and weight loss.

Tapeworm

Often transmitted through fleas, tapeworms can cause weight loss and itching around the anus.

How do dogs get intestinal worms?

Dogs can contract intestinal worms in several ways, including:

• Ingesting contaminated soil, faeces, or water.

• Eating infected animals like rodents.

• Flea infestations, which can transmit tapeworms.

• Puppies can acquire worms from their mother during pregnancy or nursing.

• Larvae penetrate through their skin. 

What are the symptoms of intestinal worms in dogs?

Common signs of intestinal worm infestations include:

• Diarrhoea (sometimes with blood)

• Vomiting

• Weight loss

• A dull coat

• Scooting or dragging their bottom on the ground

• Bloated abdomen, particularly in puppies

You won't be able to tell your dog has worms just by looking. 

The most reliable way to confirm the presence of worms is through a microscopic examination of the faeces to detect worm eggs. 

This is why prevention and regular vet check-ups are so important.

How to prevent intestinal worms?

Prevention is key to keeping your dog healthy and free from intestinal worms. 

Here’s how you can help:

• Use veterinarian-recommended worming treatments regularly. Some of the products sold by supermarkets are not very effective. 

• Practice good hygiene, including cleaning up after your dog promptly.

• Ensure your dog’s flea control is up to date.

• Avoid letting your dog eat unknown objects or other animal poo.

How often should you get your dog dewormed?

A common misconception we often hear is that pet owners believe the deworming tablet given during the annual health check-up at the vet provides coverage for the entire year.

We follow the advice produced by The Tropical Council for Companion Animal Parasites

The council members recommend:

• Puppies: Deworm every 2 weeks until 8 weeks old

• Adult dogs: Deworm every month, or as recommended by your veterinarian.

We may adjust this schedule based on your dog’s lifestyle and risk factors.

An alternative option to regular deworming is frequent faecal egg counts. If you would prefer this option, our veterinarians can help facilitate this testing.

This option may also help reduce the development of drug resistance.

Can humans catch intestinal worms from dogs?

Yes, some intestinal worms, such as roundworms and hookworms, can be transmitted to humans. This is called zoonosis.

If people get infected, the parasites can cause very serious health concerns.

Children are particularly at risk, as they are more likely to play in areas where eggs or larvae may be present. Regular deworming and good hygiene are essential to protect your family.

Will it infect my cat?

Certain intestinal worms, like tapeworms, can also infect cats. If you have multiple pets, it’s important to treat all of them to prevent cross-infestation.

Treatment for intestinal worms in dogs

If your dog has been diagnosed with intestinal worms, we will recommend an appropriate deworming treatment. 

These treatments are safe, effective, and tailored to the specific type of worm. 

Follow-up care may include:

• Repeat doses of deworming medication to address any residual worms.

• Routine faecal examinations to ensure your dog is worm-free.

• Adjustments to your dog’s prevention schedule to reduce future risk.

Protect your dog’s health with regular deworming and preventative care.
