Our dog had an allergic reaction to Frontline Plus. He broke out in welts and sores.
The vet prescribed prednisone and tonight he is panting like crazy, in addition to drinking and urinating frequently. The vet mentioned that panting might be a side effect but I am worried he is panting so fast.
Is there any concern with it progressing to a heart attack or other worse issue? The prednizone did seem to help the skin, but the panting is frightening.
