Tapeworms are long, segmented worms found in the intestinal tracts of dogs and cats. Diagnosis is made when tiny, rice sized, white segments are seen in the feces or on the hair around the anus of affected animals. Because the segments seen are actually the egg casings, tapeworms are not easily detected during a routine fecal or intestinal parasite exam. Treatment includes oral medication and/or an injection. Flea control is very important in preventing re-infestation because the primary mode of infection is by the ingestion of fleas. Your pet chews at the flea, often times ingesting the flea as well as the tapeworm egg being carried by the flea.
