Negative Positive
Title: Did not work
Review: I have never had problems with fleas on my 7 lb yorkie. We switched over from Revolution to Advantage because of the great price and free shipping here on Amazon. Poor dog got fleas after starting Advantage and even putting the medicine on again after less than a month, the fleas are still alive and healthy! Maybe this is a bad batch from Amazon but I'm throwing the last 4 months away and going back to Revolution.
