Schematic illustration of Dipylidium caninum
The larval flea ingests the egg. The cysticercoid develops in the flea, reaching infectivity in the adult flea about 1 day after the flea has found a host. When the dog ingests an infected flea while grooming, the cysticercoid is digested out, the protoscolex attaches to the small intestinal wall and the worms begin to form proglottids. Gravid proglottids, containing the eggs, detach from the end of the worm and pass out in the feces. The prepatent period is about 2 weeks.
