subject: Feeling Flea-Free With Frontline Plus for Dogs [print this page] Frontline Plus for dogs comes in a handy over the counter three pack. This is great because it can keep one dog flea free for an entire summer. You'd only have to purchase four packages to keep them flea free for an entire year. The downside, if you were just trying to get through the summer with two dogs you'd have to buy at least two boxes, unlike some of the competitors who offer four doses in a single box.
