Tapeworms

• The definitive host of the cucumber tapeworm is a
  dog or a cat (occasionally a human). Fleas and
  lice are the intermediate host. the dog or cat
  becomes contaminated when the eggs are passed in
  the feces, and the flea or louse ingests the
  eggs.  The dog or cat (or human) is infected when
  they ingest a flea or louse.  Hence the
  importance of controlling fleas on your pet!
