Infection with adult pulmonary trematodes causes lung cysts in both dogs and cats. The adult flukes are reddish-brown and oval and measure about 14 by 7 mm. 6 Eggs are golden brown and measure 75 to 118 by 42 to 67 mm. 1 The eggs are passed through the lung cyst wall, where they are coughed up, swallowed, and passed in the feces. The life cycle includes several snail species as the first intermediate host and crayfish or crabs as the second. Patients become infected via ingestion of raw crayfish or a paratenic host infected with the metacercariae. 6 The trematode penetrates the intestinal wall, and within the peritoneal cavity, the flukes can pass through the diaphragm where they enter the lungs and establish an infection.

Cercariae develop into metacercariae after penetrating the skin of tadpoles. 2 Frogs, snakes, and mice become infected by ingesting the tadpoles. Dogs and cats then become infected after ingesting the intermediate host.

How do dogs get tapeworms?
There is a cycle through which dogs get tapeworms: 1 First, the dog will ingest a host that is harboring tapeworm eggs, most often an adult flea. There are a few ways a dog might ingest a flea, such as self-grooming, or grooming a canine or feline housemate. Other animals that are potential transmitters of eggs include birds, rabbits, or rodents, which even a well-fed dog might scavenge for. 2 Once digested, the tapeworm eggs settle into your dog’s small intestine. There it will develop into an adult. 3 The adult tapeworm is made up of lots of small segments, each about the size of a grain of rice, called proglottids. Adult tapeworms usually measure anywhere from four to 28 inches in length. 4 As the tapeworm matures inside the dog’s gut, these segments break off and end up in the dog’s stool. Since these segments contain tapeworm eggs, the cycle will begin again, with a new host and most likely a new recipient.
