Hymenolepis nana
Dipylidium caninum: proglottid (macro) and 6-hooked embryos in eggs (packets or single eggs)
Dipylidiun caninum
Once again, the dog or cat relieves it's anal itch and passes its double pores proglottids into its human dwellings. The proglottids disintegrate and release the brood of packets of eggs. Dipilidium caninum has been found not only in dog but also on cats.
The freshly passed proglottids are motile but soon shrink in size to that of a small rice grain and become motionless.

Adorable little proglottids!
My dog has fleas
As there are no measurements available for the ova and no great detail on the proglotidd, my diagnosis would be solely based on the appearance of the ova and the patient being a child. My diagnosis would be Hymenolepis nana. 6 hooklets can be seen in the oncosphere, and polar filaments can just about be seen.

when dealing with a D. caninum infection don' forget to treat your pets and possibly premises for fleas.
