Advantage II Dog 4-Pack for Dogs between 11 and 20 lbs
Advantage II is a monthly flea preventative for dogs and cats that offers comprehensive flea protection by killing adult fleas, larvae, and eggs. Plus, it kills fleas through contact, which means fleas don't have to bite your pet to die. Advantage II also treats, prevents, and controls lice on dogs. Note: Advantage II does not kill ticks, so if you want tick protection as well, we recommend Frontline.
