Flea treatment for sensitive skinned dog?

[ASecretLemonadeDrinker]

When we got our dog they told us in passing she was sensitive to frontline and they used something else. It is written down in the paperwork but I have to dig it out... anyone know what is a good flea treatment for sensitive skin? Thanks

My dog has sensitive skin and we something called Advantix or something along those lines is that it?

How about Program? I use it in conjunction with frontline but it can be used alone (it's a pill)

Advocate, Stronghold?
