Most dog owners first notice tapeworm as small, flat, rice-like segments stuck to the fur under the tail or moving on a fresh poo. That is usually the flea tapeworm, which is more of a nuisance than a danger to the dog. But in rural Australia there is a tapeworm that matters far more to people than to dogs: the hydatid tapeworm, Echinococcus granulosus. Dogs pick it up from raw sheep, cattle or kangaroo offal, and its eggs can cause serious cysts in human organs. Knowing which tapeworm your dog is exposed to shapes how you prevent it.
Key takeaways
- Tapeworms are flat, segmented worms that live in the small intestine.
- The flea tapeworm (Dipylidium caninum) is spread when dogs swallow fleas while grooming.
- Taenia tapeworms come from eating raw meat, offal or prey such as rabbits.
- The hydatid tapeworm comes from raw offal and is a serious public-health risk in Australia.
- Many general worming products do not cover tapeworm, so check the label for tapeworm activity.
The main tapeworms in Australian dogs
Flea tapeworm (Dipylidium caninum)
Flea larvae eat tapeworm eggs in the environment, and the dog becomes infected by swallowing an adult flea. Segments look like grains of rice or cucumber seeds and can wriggle when fresh. Controlling fleas is essential, or the tapeworm will keep returning. Our guide to the flea life cycle explains why.
Taenia species
Dogs acquire these by eating raw or undercooked meat and offal, or by hunting rabbits, rodents and other animals. Segments are larger than flea tapeworm segments.
Hydatid tapeworm (Echinococcus granulosus)
The adult worm is tiny and dogs usually show no signs. Dogs become infected by eating offal (especially liver and lungs) containing hydatid cysts from sheep, cattle, goats, pigs, kangaroos and wallabies. Eggs passed in the dog's faeces stick to fur and contaminate the environment. If a person swallows them, cysts can grow slowly in the liver, lungs or other organs over years and may need surgery. Rural and farm dogs, working dogs and dogs fed raw game meat are at highest risk.
Spirometra
Sometimes called the zipper tapeworm, it is picked up from eating frogs, reptiles or other wildlife and is seen in parts of Australia, particularly in cats and dogs that hunt.
Signs of tapeworm
- Rice-like segments on the fur around the bottom, on bedding or in faeces
- Scooting or licking under the tail
- Mild weight loss in heavy infections
- Occasional vomiting or digestive upset
- No signs at all, which is common, especially with hydatid tapeworm
Scooting is often caused by full anal glands rather than worms, so a vet check is useful if it persists.
When to see a vet
Tapeworm itself is rarely an emergency.
Emergency now: a dog that is collapsed, vomiting repeatedly, has a swollen painful belly or bloody diarrhoea. These signs suggest something more serious than tapeworm.
Same day: a puppy with worms and diarrhoea, poor appetite or lethargy.
Book a visit: segments seen in a bright dog, scooting that persists, or if your dog has eaten raw offal or carcasses and you want advice on hydatid prevention.
What to do
- Collect a segment or fresh faecal sample in a sealed container for your vet. A photo also helps.
- Start or review flea control for every dog and cat in the household.
- Pick up poo promptly and bin it, wearing gloves.
- Wash your hands after handling your dog, especially before eating, and supervise children.
- Stop feeding raw offal and keep dogs out of carcass and slaughter areas.
How vets diagnose and treat tapeworm
Diagnosis is often based on seeing segments. Tapeworm eggs are not reliably found on routine faecal tests, and hydatid infection in dogs is usually not detectable without specialised testing. Treatment uses a product with an ingredient active against tapeworms (praziquantel is the most common), given according to the label and your vet's advice. Flea tapeworm will come back unless fleas are controlled at the same time.
Prevention
- Use consistent flea control on all pets.
- Choose a worming program that includes tapeworm cover. See our guide to dewormers for dogs.
- Never feed raw offal from sheep, cattle, goats, pigs or macropods. If offal is fed at all, cook it thoroughly first. Home freezers are not cold enough to reliably kill hydatid cysts.
- For rural, farm and working dogs, state health and agriculture departments generally advise tapeworm treatment every six weeks. Ask your vet how this applies to your dog.
- Keep dogs away from carcasses and slaughter areas, and bury or burn offal so dogs cannot reach it.
Tapeworm and people
Children can occasionally become infected with flea tapeworm by accidentally swallowing a flea. Hydatid disease is more serious and can cause cysts in the liver or lungs. If you have concerns, particularly in a rural household with working dogs, speak to your GP.
FAQ
Can I catch tapeworm from my dog?
It is possible but uncommon. The main human risk in Australia is hydatid disease from dogs that eat raw offal.
Why does my dog keep getting tapeworm?
Usually because fleas are still present, or the dog keeps eating prey or raw meat.
Will I see hydatid tapeworm in my dog's poo?
No. The adult worm is only a few millimetres long and dogs rarely show signs.
Does my all-wormer cover tapeworm?
Check the label. Some products cover tapeworm and others do not.
Talk with a vet
If you have spotted segments or want help setting up a worming plan for a rural or working dog, a Dial A Vet consult can help. A collapsed dog or one with severe vomiting or bloody diarrhoea needs an in-person emergency vet straight away.
