Lungworm infection questions
How is lungworm transmitted?
Lungworm is transmitted through the ingestion of infected slugs, snails, or frogs. It is not passed directly from one pet to another; an intermediate host is required.
Can lungworm affect humans?
No, the lungworm species that affect dogs and cats are not considered zoonotic and are not transmitted to humans.
What is the recovery time for lungworm?
Recovery usually takes a few weeks with proper veterinary treatment.
How can I protect my pet from lungworm?
Regular deworming and preventing your pet from eating slugs, snails, and frogs help reduce the risk.
What should I do if I suspect lungworm?
Consult your veterinarian promptly for diagnosis and treatment.

Lungworm Infection in Pets
Overview
Lungworm infection is a parasitic disease impacting the respiratory system of pets, particularly dogs and cats. It's caused by nematode parasites such as Angiostrongylus vasorum in dogs and Aelurostrongylus abstrusus in cats. These parasites reside in the lungs and can lead to severe health issues if left untreated.
Causes
Lungworm infection primarily occurs when pets ingest larvae from infected slugs, snails, or contaminated water and food. Once ingested, the larvae migrate to the lungs, where they mature and reproduce.
