Samantha has her second ear infection in as many months. In November it was her right ear, this time her left. Its, this time, a yeast only infection, last time both yeast and bacteria. She is an otherwise healthy eight year old. Vet says its allergy related and if it recurs again, (soon???) he wants to put her on preventative medication. One he mentioned would be a once a month injection, the other daily oral medication. Any input would be helpful, I loath to put her on medication, but certainly want to do everything possible to avoid future ear infections. Anyone have any experience with either of these medications? I don't know what the injection medication is, the oral is an anti inflame, anti itch medication.
