Tapeworm infections are usually diagnosed by finding segmentsâwhich appear as small white worms that may look like grains of rice or seedsâon the rear end of your dog, in your dogâs feces, or where your dog lives and sleeps.

They are usually identified by the animals they come from -- for example, Taenia saginata from beef, Taenia solium from pork, and Diphyllobothrium latum from fish. Tapeworms have a three-stage lifecycle: egg, an immature stage called a larva, and an adult stage at which the worm can produce more eggs. Because larvae can get into the muscles of their hosts, infection can occur when you eat raw or undercooked meat from an infected animal.
