My dog has had an ear infection for the past 12 weeks and nothing seems to help. First it was a yeast infection, then it was a rod bacteria infection, now it is an enterococcus infection, or so they say. She has been on 3 different medications, including baytril and postatex and 2 different antibiotics, has had a deep ear cleaning which required sedation and has had several ear swab/cultures. Has anyone else had this problem and, if so, how did you finally treat it. I am starting to doubt my vet's advice as she is now talking about doing surgery (to widen the ear canals - NOT an option for me), blood work, thyroid panels, etc. Can anyone help ?????
