Over the past few months Thor has had constant fleas! I've been using Frontline and Frontline plus since he was a puppy and never really had this big of a problem. He has been having fleas all month long!!!! What is up with this? OUr other dog is having the same problem and it's driving me and them nuts! Itchyin' away, and I am STILL FINDING FLEAS!!!!

PLease enllighten me! What in the world is going on?????

Thanks!
