Tapeworm in Dogs and Cats: Signs, Treatment and UK Costs
Tapeworm is one of the most common internal parasites in UK dogs and cats. Unlike roundworm, tapeworm infections are acquired through specific intermediate hosts — fleas or small mammals — so the route of prevention and treatment is slightly different. This guide explains the most common tapeworm species in UK pets, what to look for and how to treat effectively.
Key takeaways
- Dipylidium tapeworm is transmitted by fleas — effective tapeworm control requires simultaneous flea treatment, as re-infection is rapid without it.
- Praziquantel-based wormers (Drontal, Milpro) are effective and widely available; using a written prescription to buy online reduces costs.
- Dogs that hunt or travel to Europe should be wormed for Echinococcus regularly — this parasite poses a serious public health risk.
Types of Tapeworm in UK Dogs and Cats
The most common tapeworm affecting UK dogs and cats is Dipylidium caninum, transmitted via fleas. Pets become infected by ingesting an infected flea during grooming. The second most common is Taenia species — Taenia pisiformis in dogs and Taenia taeniaeformis in cats — transmitted by hunting or consuming raw meat from infected prey (rabbits, rodents, birds). Multiceps and Echinococcus species are less common but of note — Echinococcus granulosus and E. multilocularis (hydatid tapeworm) are important in rural dogs with access to livestock or wild animal carcasses.
Echinococcus multilocularis has become of increasing concern in the UK following the end of mandatory tapeworm treatment for dogs returning from Europe. Dogs can carry this species without showing signs, and in humans the larval stage causes serious, potentially fatal liver disease (alveolar echinococcosis). The RCVS and BVA have highlighted concerns about this since rules changed at Brexit.
Signs of Tapeworm
Tapeworm infections are often detected by owners noticing motile segments — white or cream-coloured, rice-grain-sized segments — around the dog or cat's anus, in the fur around the hindquarters or in the faeces. These segments are individual proglottids, each containing tapeworm eggs, that break off from the end of the adult worm. They may be seen moving shortly after passing — they contain muscle fibres and can inch across the surface.
Systemic signs of tapeworm are often mild in adults but can include scooting along the floor (due to perianal irritation), licking the anal area excessively, occasional vomiting if segments are vomited, and mild weight loss or poor coat condition with heavy infections. In animals with heavy tapeworm burdens — particularly kittens and puppies — growth retardation and intestinal discomfort may be more apparent. Routine faecal testing as part of a wellness plan can detect tapeworm eggs even when no segments are visible.
Treatment
Praziquantel is the active ingredient effective against tapeworm. It is available in tablets, spot-on preparations and combination wormers. Products include Droncit tablets (praziquantel only), Drontal (praziquantel + pyrantel for dogs and cats), Milpro, Cazitel and combination spot-ons such as Broadline for cats and Advocate plus separate tapeworm treatment for dogs.
Treatment costs approximately £5–£15 per treatment depending on the product and animal size. Because Dipylidium caninum is transmitted by fleas, treating tapeworm without simultaneously treating fleas will result in rapid re-infection — flea control and tapeworm treatment must be done together. Cats that hunt should be treated for tapeworm every one to three months. Milpro or Drontal Plus combination products are convenient and cost-effective for regular use. Using your vet's written prescription to purchase products from a licensed online pharmacy typically offers significant savings.
Echinococcus Risk and Prevention
Echinococcus multilocularis is a significant public health concern. Dogs that travel to continental Europe and return to the UK can harbour this tapeworm. The risk is highest in dogs that hunt, eat raw meat from foxes or rodents, or spend time in rural areas where the definitive host (foxes) and intermediate hosts (voles, rodents) are abundant.
Prevention includes regular worming with praziquantel (effective against Echinococcus), avoiding feeding raw offal or carcasses to dogs, preventing dogs from hunting and consuming wildlife, and seeking advice from your vet if your dog has recently travelled to a high-risk area of Europe. The RCVS recommends that dogs returning from Europe be treated with praziquantel by a vet within 24–120 hours of re-entry to the UK, as at the time of the relevant requirement under PETS travel rules.

Common questions
Dipylidium caninum can infect humans if an infected flea is accidentally swallowed — this is rare and most commonly occurs in young children. Echinococcus species are more serious — the larval stage can cause cysts in human organs (hydatid disease). Regular worming and good hygiene minimise these risks significantly.
If your indoor cat has no fleas and does not hunt, tapeworm risk is low. However, flea infestations can affect indoor cats, creating Dipylidium risk. Most vets recommend at least twice-yearly tapeworm treatment for all cats and monthly for those that hunt. A reliable flea control programme is the most important preventive measure.
Praziquantel works rapidly — most tapeworm is killed and digested within 24 hours of treatment. Owners sometimes see increased numbers of segments passed in the faeces in the day or two after treatment as the dead worm breaks down. No visible segments should be present after 48–72 hours.
