Tapeworms are a common intestinal parasite in Australian dogs - and unlike other worms, they often cause no obvious symptoms, so your dog might be harbouring them without you knowing. This guide covers how to recognise a tapeworm infection, how treatment works, and how to keep your dog (and your family) protected. For a full guide to intestinal worms in dogs, see worms in dogs.
What do tapeworms look like?
Tapeworms are flat, white, segmented worms that live in the small intestine. They look exactly as the name suggests - like a length of tape - though you're more likely to spot individual segments than an intact worm. These segments are shed into the faeces and look like small grains of rice or sesame seeds. You may spot them under your dog's tail, on their bedding, or in their faeces.
There are four tapeworm species that can affect Australian dogs, each with a different intermediate host.
- Dipylidium caninum (the flea tapeworm) - the most common tapeworm.
- Taenia species are contracted through raw meat or prey animals.
- Zipper worm (Spirometra erinacei) is predominantly a tapeworm of cats, however dogs that hunt, scavenge, or drink from waterways are most at risk.
- Echinococcus granulosus (the Hydatid tapeworm) is less common but the most serious species from a public health perspective, especially in rural areas.
What are the signs of tapeworms in dogs?
Most tapeworm infections are picked up when owners spot the rice-grain-like segments around their dog's bottom or in the faeces. Many dogs show no other symptoms at all - tapeworms feed on intestinal contents rather than the host itself, so they cause minimal damage in light infections.
In heavier infections, particularly in puppies and senior dogs, signs can include:
- Scooting or dragging the bottom along the ground
- Biting or chewing around the tail area
- Weight loss alongside a ravenous appetite
- Diarrhoea, vomiting, or abdominal discomfort (in severe cases)
If you spot segments or any of these signs, take your dog to the vet and bring a faecal sample along if you can.
How do dogs get tapeworms?
Tapeworms can't be picked up directly from eggs in the environment - they require an intermediate host as part of their life cycle. Your dog has to eat the intermediate host to become infected.
The most common route is via fleas. The flea tapeworm (Dipylidium) uses fleas as its intermediate host: flea larvae consume tapeworm eggs from faeces, and dogs get infected when they swallow an infected flea while grooming.
Taenia and Hydatid tapeworms spread through raw meat or the organs of prey animals such as sheep, rabbits, and hares.
The zipper worm (Spirometra) uses a more complex route involving water-based crustaceans and then frogs, lizards, or snakes - dogs can pick it up by drinking from contaminated waterways or eating infected prey animals.
How are tapeworms treated in dogs?
The active ingredient used to treat tapeworms is praziquantel, which dissolves the worms within the digestive tract. This means you usually won't see your dog passing worms after treatment -which can feel anticlimactic, but is a good sign.
It's worth knowing that the zipper worm (Spirometra) requires four times the standard dose of praziquantel, so your vet will want to confirm the species before prescribing. For severe or recurring infections, a longer treatment course may be recommended.

How do I prevent tapeworms in my dog?
Tapeworm prevention for dogs works best when you combine regular treatment with a few practical management steps:
- Use a wormer containing praziquantel regularly - not all 'all-in-one' products or 'allwormers' include tapeworm coverage, so check the active ingredients. For guidance on frequency, see how often to worm your dog.
- Control fleas year-round - flea tapeworm is the most common type, and a successful treatment course can quickly be undone if fleas remain in the household. All pets in the home should be on a flea preventative. For more, see our flea, tick and worming guide for dogs.
- Prevent your dog from hunting, scavenging, or eating raw meat or offal
- Provide clean, fresh water and avoid letting dogs drink from waterways or puddles in bush areas (zipper worm risk)
- Clean up faeces regularly and dispose of it in a bag in the bin
Can humans get tapeworms from dogs?
Yes - and it's a good reason to take prevention seriously. Humans can be infected by accidentally ingesting tapeworm eggs from a contaminated environment, most commonly through contact with soil or surfaces around dog faeces, or from handling an infected dog's coat. Children are most at risk.
The species of greatest concern in Australia is the Hydatid tapeworm (Echinococcus granulosus), which is common in rural and farming communities. In humans, the larval stage forms slow-growing cysts in organs such as the liver and lungs. These cysts can go undetected for years, and treatment typically requires surgery or prolonged medication.
To protect your family: worm your dog regularly, clean up faeces promptly, and wash hands thoroughly after handling your dog or picking up faeces.
