Dipylidium caninum is the scientific term for Tapeworm. Other common names are: double-pored dog Tapeworm and cucumber Tapeworm.

Tapeworms live in the intestine and shed segments as them mature. The segments usually appear as small "sesame seeds" or "grains of rice" on the pet's bedding or hair around the tail and anus. A newly emerged segment (gravid Proglottid) will move much like a small worm until it desiccates (dries up). The segment is then eaten by the flea, the flea is in turn ingested by the pet (i.e. during grooming), and the pet is re-infested with more Tapeworms. Lice can also serve as an intermediate host for Tapeworms.

Special medications (dewormers) are needed for Tapeworms, and they are by veterinary prescription only. Over the counter dewormers will not work for Tapeworms. Eradicating the fleas, however, will control the Tapeworms.
