Advantage II is a monthly topical flea treatment for dogs weighing 21 to 55 lbs. It combines imidacloprid, which kills adult fleas, with pyriproxyfen, an insect growth regulator that stops eggs and larvae from developing. It also treats chewing lice. Unlike oral chewables such as NexGard or Bravecto, it needs no prescription and works on contact, so fleas die without biting. It does not kill ticks, which is the main reason owners switch to a tick product.

Owners rate it highly and many report fleas gone within a day and no reinfestation with monthly use. Complaints center on application-site irritation, the greasy residue and the lack of tick coverage.
