The flea and tick shampoo makes the fleas fall off your dog in the bath water by the dozens. Its prettty gross. The only downside is that without an actual topical medicine, the bugs will come back pretty quickly. :(
I would honestly recommend any brand for medicated flea anything than sergeants. I would rather recommend store brand items than this brand. There have been many issues with this brand's flea and tick topical and their washes.
