"After having to deal with fleas from two dogs and using the Frontline Plus product, flea shampoo and carpet/upholstery flea stuff and not having it work, I decided to try this as I remember our other dog never seemed to be bothered by fleas and I used K-9 Advantix on her. Needless to say, it has worked great. My dogs itch occasionally, but nothing like they were. I would highly recommend this product to anyone who is having flea trouble."
