In this American Heartworm Society video, Dr. Clarke Atkins, DACVIM, discusses the controversy of "slowkill" for canine heartworm disease. If your canine patient was just diagnosed with heartworm, find out if it is indicated or contraindicated to use slowkill protocols. Not only is slow kill slow, expensive, and potentially dangerous, but it can result in pulmonary emboli and secondary vascular damage. For more information, go to www.heartwormsociety.org.
