    The morphology is compatible with D. caninum proglotids. Despite its name, not only Fido carries this cestode but Felis the cat also carries the worm. Perhaps the feline species being closer to the owner, has more aptitude to share the parasite with the owner. The packet of eggs is the clue of the case.
