I honestly can't remember which one we use... Frontline or Advantage.... because the cats are on the other one so I can't remember which is which and I'm not at home to look. BUT we are now also using Comfortix. It's a pill that you give once a month and can be given along with whichever flea/heartworm pill you give. You just give it 2 weeks after the other pill. We have had no problems since and believe me, the fleas are CRAZY in our area this summer. We have stopped using the topical one you put on their neck.... just the heartworm/flea pill plus the Comfortix. Good luck!
But sorry, I've never used a dip so I can't comment on that question.
