How do you get rid of macracanthorhynchus ingens in dogs?

Answer 1

The short answer is, you don't have to do anything but wait for the infestation to pass.

Macracanthorhynchus ingens , naturally a parasite of raccoons, is occasionally found in dogs. The usual observation is of a large (8-12 cm), white, wrinkled worm passed in the feces. No clinical signs have been definitively associated with the infection. The life cycle requires a millipede as an intermediate host, but other animals may serve as paratenic hosts. The eggs look similar to those of Oncicola canis but are larger (~50 × 100 µm). Diagnosis of patent infections is unlikely because experimentally induced infections did not persist after 1-12 days of patency.
