How Do Fleas Transmit Tapeworms?

Fleas play a crucial role in how a specific species of tapeworm is transmitted between pets.

  1. The Tapeworm

    • The tapeworm species that is transmitted by fleas is the Dipylidium caninum, or D. canium for short. This species can live in dogs' or cats' small intestines.

    Tapeworm Segments

    • An adult tapeworm is made up of multiple egg-filled segments that occasionally break off and pass out of the animal's intestines when it defecates.

    Flea Larva

    • After the segments dry out and open, flea larva feed on the tapeworm eggs, and the eggs begin to develop into tapeworms inside the flea.

    Grooming

    • Sometimes when your dog or cat is grooming, he licks up and swallows fleas. When this happens, the tapeworm is able to get into your pet's small intestine and finish maturing.

    Prevention/Solution

    • In order to get rid of tapeworms completely, you must have your pet on flea prevention medication as well as a dewormer designed to kill tapeworms.
