Sushi has been itching his ears & back leg. Also licking his paws. The vet said it was allergies & gave him a shot. He also gave us pills to be used as needed. I have no clue what hes allergic to. I hate giving him meds all the time

. Does anyone else's babies have this problem? Do I have any alternative to giving him the meds. Any suggestions would help. Also I already use an oatmeal shampoo
