Vetmedin is a prescribed FDA Approved veterinary inodilator that aids in dilating veins and arteries. It also works to increase cardiac output, which lightens the workload of your dog's heart. Vetmedin may also help your dog with congestive heart failure so she can feel better and improve her quality of life. Given every 12 hours, the unique dual action of Vetmedin dilates the blood vessels carrying blood to and from the heart—reducing the preload and afterload on the heart—while simultaneously improving contractility of the heart muscle. Pimobendan, Vetmedin’s active ingredient, reduces stress on the heart while increasing cardiac output, without raising oxygen or energy consumption. Vetmedin helps dogs engage in the daily activities they enjoy. These chewable tablets have a wag-worthy beef flavor and are available in four convenient dosing sizes (2.5 mg, 5 mg, and 10 mg).
