I recently got my Springer about 6-7 weeks ago and he is one yr. old. We took him to the vet for his checkup and told her that he got ticks each and every time he went out. We asked about Frontline and she said it was a great product but suggested Advantix because she thought it worked better. We did take her advice and he has been using it now for about three weeks. I have not seen a tick on him in over two weeks. I know these products sometimes do not keep the ticks from getting on the dog, but it keeps them from " diggin' " in. I have heard good things about Frontline from some friends but my experiece with Advantix would make it hard for me not to recommend it.
