I do apply every month. But if you go to their website (I did to check to see if bathing would lessen it's affectiveness) they say that it can work up to 3 months...depending on the dog. Syd has very dry skin (we are working on solving that) and since Frontline works through the oil glands in the skin...that may be why it doesn't last for her.
