Tapeworm (Taenia pisiformis)

Taenia pisiformis is one of several parasitic tapeworms that infect dogs, which are the definitive, or primary, host with rabbits most often serving as the intermediate host. Adult tapeworms live attached to the intestinal walls of their canine host. The life cycle stage that is found in the intermediate host is the cysticercus, or bladder worm, a larval form that lives encysted in muscle tissue.
