Review title: This doesn't work at all!
Product review: I have used frontline for years, and I think that this is a knockoff of the more expensive stuff in the stores. one of my dogs has a severe allergy to fleas and self mutilates in a matter of hours when he has them, requiring steroids. Since 2 years ago I have faithfully used this product and always am impressed by how well it works when purchased for 50-60 dollars from my local store. I tried this out online, and the package seemed cheaply made, and the dogs (BOTH) didn't respond to it at all! I will go back to the 50 dollar version at my local store!
