Screen and detect heartworm infection even in patients with low heartworm burden


Heartworm disease has been found in dogs in all 50 of the United States. While heartworm is both treatable and preventable, it is a serious and deadly disease that may show no clinical signs in its early stage. Screen annually to find even low worm-burden patients sooner and more often, and begin treatment when you can do the most good.
