My Chachi is allergic to fleas also. Are you sure some fleas didnt get on her but the flea preventative killed them and she is having a flare up from that. When Chachis flared up thats what happened. The vet found dead fleas on him. Anyway he put him on prednisone which helped him. He also gave him a medicated shampoo. I say take her to the vet. |
