Dogs can become infected by ingesting infected slugs or snails or by coming in to contact with the saliva or stool of infected dogs. Depending on the severity of the infection, treatment may last as long as 2 months. Repeated doses of the dewormer may be indicated. You will know the infection is resolved after a fecal exam comes back as "negative" or containing no parasites or parasite eggs.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! If your dog has lung worms I would contact your Vet for the deworming protocol as it is usually a 2 week course. But the intent of the medication is to clear the infection. Have a good day!
