Frontline-Merck & Co., Inc. And Sanofi-aventis-Merial Product NO LONGER WORKS for fleas. Nationwide

I have puchased Frontline on three seperate occasions this fall alone and none of them have worked on my cats or dogs for fleas. I spoke with my dog groomer who said she has had many of her clients complaining of the same problem. I also spoke with my Veterinarian who is now documenting all the cases of her cleints and vet technitions who have used the product and it has not worked. Of course Frontline will not admit to it. So I am hoping the more complaints we post on line the sooner something will be done.
