Species affected: Dogs, primarily (though the number of affected cats is increasing)
Background: A parasitic disease spread by mosquitoes. Heart failure can develop when mature worms (5-9" in length) obstruct the heart.
Symptoms: A characteristic deep, moist cough, lethargy and weakness.
Diagnostics: Cardiac workup, radiology, echocardiography and EKG, blood tests.
Special Notes: Prevention includes decreasing contact with mosquitoes, herbal repellents and chemical filaricides.
Principles for Supplementation: Support myocardial function, anti-inflammatory and antioxidant action to help heal the myocardium and support the liver while more toxic compounds are used to eliminate the parasite.
