I gave my dogs a flea bath, combed out the fleas and dirt, put Advantage on them, and there are still fleas on them (and me occasionally) ARgh!! I had it for a yr, does it expire?? It hasn't helped much!! I'm losing blood w/ my dogs!!

Your package will have an expiration date on it. It may have sat on a store shelf for years before you bought it.
