While the holistic methods sound good I personally am afraid to "test" them on my yorkie because I have seen no real science behind them and if they were not to work I would have only myself to blame. I am going on my vet's advice here and I am willing to admit he knows more about these issues than a layman like myself. I use Frontline on Sophie because we have a large deer population where we live and I fear lyme disease. I used Frontline on our first yorkie "Baby" and she lived to be 16 years old with no side effects and Sophie has never had a flea, tick or any other issue either using Frontline.
