When Spencer was a pup he suffered from several bad ear infections. The vet recommended I begin using a drying solution. I did & he has not had a single ear infection since (he is now 10 1/2 years old). We currently use "Epi-Otic." It can be purchased from the vet, but it is not a prescription & I usually order it from KV Vet supply. I use it weekly on him - put some solution in each ear, massage them & then let him shake. Besides preventing ear infections, it also helps to keep his ears clean. Hope this helps.
