I work for ProbiotiSmart and have learned alot from working here and having pets, which I am happy to share with others! I have a 2 year old schoondle, Winston, that has a cronic ear infection. My vet says that is just something that we will have to deal with constantly as every time we treat it, the infection will always come back. The vet told me that one thing that is super important is to clean out the hair in Winston's ears so that there is less surface area for infections to attach to as well as it will help keep his ears dryer. I have to pull the hair out of Winston's ear's two every weeks as it grows faster than one would expect. I just use a tweezer and make sure to not go into the canal. (I don't know how you would do it any other way) Then, I follow up with an ear cleaner. I love the PSCPets.com Ear Cleaner, as it helps make the removal of the excess "gunk" easy with a cotton ball. Then, I use the Vetericyn VF Otic Rinse as that is designed to help fight infections. So far so good, as I can tell since the ears smell good and not as stinky!
