Advantage Flea Treatment for Dogs Advantage is the fastest way to a flea free home. An easy-to-use spot-on, Advantage is applied monthly. Its super ingredient stops fleas biting within 3 to 5 minutes and kills both adult fleas and larvae within 20 minutes. Since Advantage works on contact so fleas don’t need to bite, dogs suffer fewer painful flea bites, reducing outbreaks of Flea Allergy Dermatitis. Advantage is the only flea product you need as it breaks the flea lifecycle. Unlike other treatments, Advantage kills fleas in your dog’s surroundings – your home. It even provides protection for your dog when it comes into contact with other pets that have fleas. Safe for puppies of any age, Advantage provides month long protection, controls lice and is water-resistant so it won’t wash off. It’s the quickest way to the happiness of a flea-free home. Available in pack of 4.
