I've never seen a product that worked with near 100% effectiveness and then 6 months later have ZERO effectiveness.
Exactly! As I said, this wasn't a slight change in effectivenss. It went from perfect to useless in a two month period. Heck, it seemed like it was making the dog more attractive to the fleas!
In any case, I think there is more to this than meets the eye. And if there isn't, the company should have a good explanation for that sort of variation. They should be able to give a reasonable explanation as to why the product could fail so completely in such a short period. And if they said, oops, we made a bad batch but everything is okay now, I'd respect that and stick with them because up until now, for seven blissful flea free years it has been a superb, amazing product.
