Review title: Not effective anymore!
Product review: I have been using Frontline for a long time with my animals. Unfortunately, the fleas have become immune to Frontline. I started finding fleas on my dog this summer. I supplemented with flea shampoos AND giving Frontline more frequently (every 3 weeks instead of every 4). I also fogged and sprayed the house. (More $$$) This didn't help- my poor dog still had fleas. He scratched and scratched and gave himself a swollen ear. After $500 of surgery and meds for the ear- I am switching to Revolution Flea Control (and that seems to be working!!).Several vets I have talked to, and several dog owners, tell me that the fleas seem to have become immune to whatever Frontline uses. One vet tells me that he is sending back all his unused Frontline supply and will not carry it anymore.
