What can I do to prevent tapeworm? - Advanced Animal Care
As far as tapeworms go, they often come from a dog ingesting a flea. Not all fleas carry them, but some fleas do carry tapeworm eggs. Once your dog ingests that flea, that allows the egg to hatch inside your dog, and the adult tapeworm comes out. So to prevent that, you need to be sure that your dog and any other pets exposed to in the home are on effective flea prevention. That's a year-round type of thing. And if your dog's a farm or outside dog, maybe some kind of a mole hunter in the backyard, those types of rodents and things can carry fleas as well. So they possibly want to have a prophylactic deworming as far as either keeping them on heartworm prevention that deworms against the tapeworms or even deworming them each year.
