I thought I was crazy until I researched it and found out A LOT of people are having the same problem!!! I have used frontline plus for years and years, and I have always LOVED it, but something is wrong with it this year. I called Frontline and they were horrible and rude! I looked around online and it seems like there are a lot of people out there that have the same problem. Something is different, and it is NOT working!! I am going to report it to the BBB and anyone else that will listen, I reccomend everyone do the same. They shouldn't be able to get away with insisting nothing is wrong.
