I have a 2 yr old pek. I put Frontline Plus on him and ever since he has been biting and itching until he bleeds. I took him to the vetand they gave him antib. & prednisone and it worked for a while but now it is back. He doesn't have fleas that I can find and I don't know what it could be. help!
Maybe your pet is having a reaction to the frontline?? I have not seen a generalized reaction, only a local reaction to frontline. Maybe your pet needs to be on prednisone for a longer period of time. Talk to your vet about it. Good luck, vetcare
