CARESHARE I just treated my dog for fleas with advantage shampoo. How soon can I give her the Trifexxus preventative? She was due for it when I found a flea on her but wasn't sure if I should give her both at the same time.

I would suggest to ideally wait 7 days before giving any other treatment to be on the safe side. The two might be given together as they have different active molecules but I would recommend always to give them at different times (one week apart).
