Frontline Plus sucks! We tried it month after month and once Sophie got fleas we could not get rid of them until I switched her to Sentinal. Which also has its downfalls. It does not kill fleas but will not allow them to lay eggs. At least we are not having outbreaks anymore. We might have one every once in awhile but I can deal with that. Just give her a Capstar and you are good to go. I know you are mainly concerned about a allergic response but the product sucks for fleas anyway, so you might as well not waste your time. I just don't want you to have to go through the fun experience I have had with my little girl.
