![]() ![]() Once a mature tape segment passes out in faeces, it breaks open, releasing its eggs. While the adult tapeworm (which can be over 40cm in length) lives in the small intestine of the dog, fox or cat, it requires fleas and lice to complete its life cycle. Hydatid tapeworm ( Echinococcus granulosus).Taenia ovis, the cause of sheep measles.The most common tapeworms infecting dogs and cats in Australia are: Often these individual segments are seen around the anus of the dog or cat, looking like rice grains attached to the fur. In the neck region, new segments are continually being formed, while the mature segments at the end – which can contain large numbers of eggs – are cast off and pass out in droppings. The head usually has suckers to allow the worm to attach to the intestinal wall. Structurally, tapeworms are flat with a head and neck, followed by numerous segments, each with its own reproductive organs. And for humans, the hydatid tapeworm can be fatal (click here for more information on human hydatidosis). It’s the involvement of livestock in the life cycle of some tapeworms that has the greatest impact – not on the dog, but on the end product at the abattoir. The key difference is that every dog and cat tapeworm species requires an intermediate host to complete its life cycle.ĭepending on the tapeworm species, these intermediate hosts can include fleas, frogs, kangaroos and domestic animals such as sheep and pigs. Tapeworms are different in structure and behaviour to other intestinal worms of dogs and cats.
