Lungworms in Dogs




Lungworms are treatable with anti-parasitic (anthelminthic) medications. Commonly used medications include:


  • Fenbendazole
  • Albendazole
  • Oxfendazole
  • Ivermectin
  • Moxidectin
  • Praziquantel
  • Levamisole


These medications should eradicate the worms over time and will help clear the animal of the infection. In severe cases, where secondary infections and lung damage have occurred, other medications such as corticosteroids or antibiotics may be necessary to help your pet recover.


Living and Management


An infection with lungworms does not typically last long. The dog often eliminates the worms by coughing them up or excreting them through the feces. Then, as long as the prescribed medication is given and the dog does not develop a secondary lung disease such as pneumonia, the prognosis is good.


In severe cases, repeat X-rays or fecal examinations may be needed to follow up.




To prevent exposure to rodents, birds, or other animals which may carry the lungworm larvae, dogs should not be allowed to roam outdoors.
