I gave my dog a bath and applied front line about 8 hours later when I figured he was dry however I still see fleas and after some research read that you need to wait 48 hours after a bath to apply so that the oils on his skin can return because that's how the frontline is distrubuted. Since it seems I may have not applied it effectively, can I put another application of frontline on him or must I wait a month? I'm seeing about 4 - 6 very small fleas on him at a time. I remove them but they come back. In addition to frontline, I've used Bio carpet flea powder and sprayed my back yard with spray to kill fleas. Is this something that is just going to take time? I haven't noticed fleas on myself, and when I do find them on my dog they are the real small kind.
