frontline doesnt do it for my guys and gals at all nor frontline plus
i buy the advantage kits on ebay..works great! no fleas and my neighbors are the flea causing problems...they have big dogs, dirt and tall weeds and they never put flea meds on them..and they stay in the house some too...eww smells like dirty wet dog there! but any how i use this because of the neighbors yard and dogs and it works excellent
good luck |
