Tapeworms are intestinal worms that are made of up segments. The most common type of tapeworm has an intermediate host of a flea which when eaten by the dog or cat, usually during self-grooming, causes the worm to develop in the patient. The most common description by clients is rice-like segments found on the stool or around the pet's anal area. These segments can move when first passed but die quickly. The tapeworm is easily treated but  flea control  is necessary. These are the segments usually seen.  Other types of tapeworms have intermediate hosts of rabbits or rodents and are often seen in outdoor cats.
