Advantage Multi Topical Solution for Dogs

Topical heartworm preventatives are another common way of administering protection to your pooch. For the best dog heartworm prevention that can be applied topically, our vets recommend Advantage Multi for Dogs.

This monthly solution protects against heartworms, fleas, roundworms, hookworms, whipworms, and sarcoptic mange. The active ingredient, imidacloprid, kills fleas through direct, physical contact, so they don't have to bite your dog to die.

In a controlled study funded by the manufacturer, the combination of imidacloprid and moxidectin found in Advantage Multi Topical Solution was shown to be capable of preventing heartworm infection and disease for the entire month it was used. Our vets like that these ingredients work against microfilaria, or baby/larval heartworms, as well.
