How should I apply Frontline Plus, Feline Advantage Multi, or Revolution to my pet?
Topical flea medicines need to be applied high on the back between the shoulder blades where the pet will not be able to reach it to lick it off. For the medication to be fully effective, it is important to separate the hair coat and apply the medication directly to the skin. In larger dogs, you should be able to apply it to multiple spots down the back. If you have just bathed your pet, you may apply the preventative after s/he is completely dry. Do not bathe for at least 2-3 days after applying the preventative.
