I gave Jack his first application of Frontline over a month ago. I did not put the entire application on him since he was small and only about 8-9 weeks old (thanks in part to my mother's worry) so I did about half instead. He got his second (full) application about 2 weeks ago. He still has fleas! And he's passed them on to Asher (who has also gotten 2 applications of Frontline). I've only noticed them on Jack, I've not found fleas around the house anywhere. I don't know what to do to get rid of them! I thought the Frontline would do the job. I realize the first application probably didn't do any good since I didn't put the whole amount on at once, but shouldn't the second application have killed the fleas? What else can I do?
