The adults mate and produce eggs. Pups can also be infected directly from the larvae in the bitches muscles. A dog can eat this rodent and larvae will then begin migration in the adult dog. They soon go dormant. In a bitch the dormant larvae become reinfective during the third trimester of pregnancy.
Some larvae migrate to the small intestines and others migrate to the unborn pups.
In the intermediate hosts and accidental hosts, the larvae will continue to migrate and that can cause problems to the host.
