I have three doberman which all use Advantage, but the youngest always breaks out from it with red dots under her coat. After about a week these bumps dry up and then she has dry flaky skin. I have tried Revolution and Frontline and she still breaks out. They all stay in the house and I don't want her to get fleas. Is she just sensitive or is she allergic to the ingredients. I don't know what to use to keep the ticks and fleas off of her. The other two tolerate this just fine.
You may want to try Program or Sentinal. These are both oral flea preventatives. Talk to your vet about it. vetcare
