Nuheart for Large Dogs is specially formulated to provide reliable monthly protection against heartworm disease in dogs weighing 51-100 lbs. This easy-to-administer oral tablet contains 272 µg of ivermectin, which works to eliminate heartworm larvae before they develop into adult worms.

The small tablet size makes dosing simple, while the palatable meat flavor helps ensure easy acceptance, even for picky eaters. Designed as a cost-effective alternative to Heartgard, it offers dependable protection without compromising on quality.

With consistent monthly use, Nuheart helps support your dog’s long-term health by preventing heartworm infection before it can progress.

How it helps

Nuheart contains ivermectin, an antiparasitic ingredient that works by eliminating the early (larval) stages of heartworms before they mature into adult worms. By interrupting the life cycle within the first 30 days of infection, it helps prevent the development of heartworm disease. Regular monthly dosing ensures continuous protection and reduces the risk of long-term complications associated with heartworm infections.
