Review title: Doesn't work!
Product review: I don't know if the fleas have become resistant to the ingredients or the product just doesn't work anymore, but I applied Frontline to my dog and he had fleas crawling on him a week after application. I took him to the groomer for a flea bath and she told me that alot of people were saying that Frontline wasn't working on their pets. She recommended Advantix.
