Frontline Gold

Frontline Gold is a topical monthly flea and tick preventative for dogs and cats. One dose of its triple-action formula kills fleas, flea eggs, larvae, chewing lice, and ticks for a full month. Frontline Gold has a new ingredient, pyriproxyfen, which helps kill the next generation of flea eggs and larvae before they have a chance to develop into adult fleas. Frontline Gold starts killing fleas in just 30 minutes.
