Thank you---I have just ordered some Oil of Oregano. Another person suggested Grapefruit Seed Extract so I'm going to try that and if it doesn't seem to correct the problem the Oil of Oregano should arrive. My dogs ears are really bad, itchy, smelly and gooey. He goes to an open field a few times a day and is always rolling around so I'm sure reinfecting himself. Seems though it's always his left ear and the stuff from the vet is totally useless. It works for a few days and then I can start to smell it again. It was so nice of you to share this information.
