Crenosoma vulpis or lungworm is common in the United States. Symptoms include coughing and respiratory distress. Lungworm can lead to death. Diagnosis can be determined in post-mortum or necropsy exam. Larvae are excreted in the feces and become infective after one week. Frequent removal of feces and clean living conditions will break the cycle.

Lungworm is treated with a standard dewormer such as Ivomec.
