Hi—I used frontline plus on my 35 lb 10 month old golden mix on 10/1, but I just found a flea on her! Is it ok to put another dose on her?

Yes, you can safely apply every 2 weeks if needed. However, frontline does not repel so the fleas that are in the environment will still have to get on Molly in order to be affected by the frontline, so there is chance the flea just ingested the medicine and you found the flea prior to it killing the flea
